- This is a video showing you how to install a 3 in 1 Start Relay. These are a universal set of relays you can use in place of the factory relays installed on your compressor.
You would want to use these to save a few bucks. These are usually a lot cheaper than the manufacture's replacement parts.

This item saved me hundreds of dollars. It is very easy to install. After installation the compressor fired right up. Thanks a bunch!
Thanks to this video I was able to fix my 12 yr old Whirlpool ED5FVGXVS00 which had suddenly quit working one day. One observation though... When I connected the two black wires on the 3 in 1 for power I didn't think the hot and neutral sides mattered. It is not marked or mentioned in the instructions. Unknowingly I had crossed them. This had the side effect of making the condenser fan upstream to stop working. When I swapped the power connections to 3 in 1 everything worked fine.
Bought one from Grainger today for under $15, installed in less that 15 minutes to fix my Hisense Chest Freezer. Worked like a charm. Thanks for the video.
Saved my refrigerator today, installed a similar universal start relay/capacitor/overload I'd purchased in 2015. Back then, I purchased factory replacement locally (about $80) and used that, only lasted 6 years. Of course, Amazon has for under $15 for factory ones, but next day delivery, so I installed the universal ERP810 one I had at the house.
While this video is 7 years old, it’s still timely. My fridge stopped running so this 3 n’ 1 got it running in no time. I paid $12 on Amazon because Prime would have it delivered the next day. Thank you!!!!
The guy that made these videos passed away years ago, but his videos and help live on
Informative video. It's remarkable what I've been able to fix watching instructional videos on UA-cam. So, for all the people you've educated to solve their own problem, I'd like to say thank you. My hope is that you truly understand how valuable your guidance is and feel awesome knowing how many people you've help. Oh, and you're single handedly keeping refrigerators out of landfills... Thanks, Rockstar.
Now, my case. I installed a Supco RCO210 3 in 1 Hard Start Capacitor on a 20 year old Kenmore top freezer model. New part was > $50 so I wanted to try the cheapest fix possible. After bumbling around to figure out if the compressor was still electrically sound, I ordered the Supco relay.
There was another question below about how to size the Supco relay. Simple: I called Supco. These compressors are rated for a certain amperage; I found it on my compressor. After checking with Supco, they told me I needed the 210, not the 410 I had purchased. I was also concerned about lifespan. Supco told me I could leave it as a permanent replacement.
Nine months after installing the Supco 210 relay, this fridge failed again. Same symptoms so simply bought another Supco 210 relay. (As an aside, after the first failure I put a temp sensor from my Acurite weather station package in the fridge. An alert fires when it goes above 40F. Excellent way to prevent food/$$$ loss. I can monitor on my phone.)
Installed new relay but it did not solve the problem. Maybe it's the thermostat. Going there next.
Update #1: used a multimeter to test compressor and thermostat. Both returned expected values. I also jumped the leads which went to the thermostat. No joy (compressor and condenser fan did not start).
I then checked power to the compressor and condenser fan. Nothing. So now the question is, "why not?" Control board? And thoughts/guidance would be appreciated. Thanks.
Update #2: so working back up to the thermostat, I found it was not getting power either. The issue was a "cooked" Refrigerator Adaptive Defrost Control Board (model #2304099). I unscrewed it from its mounting, flipped it over and saw a burn mark on board. Apparently cooked by a recent power outage. Found it on Amazon for $40.
Super psyched that 1) there will be one less fridge in the landfill, 2) to learn how a fridge actually works (not much to it, really, even understanding basic power wiring was pretty straightforward, 3) it only cost me my time and $40 (all service teams -- if they even agreed to work on a 19 year old unit -- wanted ~$120 just to show up...). and 4) I fixed it.
Hopefully this helps someone else. And, once again, thanks Bill. You started me on a success repair. Very appreciative. Have an excellent day. Best, Mike
Mike!!! Thank you for your off-air/video Tesh. comment! I have watched Bill Newberry videos many times and Truly enjoy them! Your comment was First Rate!
Sadly he past away years ago
that was absolutely a fantastic video I'm going to try this tomorrow morning because I have fallen into a situation where I need a refrigerator fix for an apartment unit and that's what I'm looking at as I feel it's probably the starter cap is gone bad but to know how to check the compressor and to get aI'm going to fall this man's instructions and that was so freaking helpful I can't believe it I don't know how to thank you thank you so much
I have used them for over 30 years there great just match the right 3&1 to the compressor size 1/5 to 1/4 and so on good video
When i worked hvac we put these on and kept them on older outdoor a/c condenser units. (Units that were aged worn down tired but these seemed to get some customers through the hot summe season or 2) also better for compressor lug start ups.
You are great. Thx for the advice. My garage fridge is working great again. I tried the single parts, capacitor, etc.... They don't work. This 3 in 1 is amazing
great job Bill, 3n'1 not bad for emergency, I learned some today. Kep on!
I loved the video I am a 36year Refrigeration mechanic I have used these and only these solid state relay capacitors for more than 15 years, I have great success they work great, I went to a commercial fridge about 2 weeks ago it had had these electrics on it for 12 years the compressor was 19 years old, the original electrics lasted 7years, 2 weeks ago the solid state electrics did fail, the windings added up perfectly I put another solid state relay capacitor on it and away it went again. A company who I have fixed there rental commercial fridges say they have saved thousands every year since I started using these. Also I always have something in my van to get a compressor going . I have one set that does from 1/12 hp to 1/2hp and another set that does from 1/2hp to 5hp so I never get stuck.
So the wide-range RCO210 (1/12hp thru 1/2hp) works just as well as the narrower-range models?
@@markg6860 yes definitely I’ve seen many last for more than 10 years
thank you for sharing, very good, practical, easy to follow, good teacher.
Use em all the time at work matter of fact have one on my freezer. Great item. Never had a problem leaving them on a unit
I am trying to fix my chest freezer but it is confusing that there are 1/12 hp , 1/4 , 1/3 and etc. Which one should I give it a try?
hey bill, i'm from guyana, i normally use a solid state relay..." icg-2 series phase failure relay protector " and trust me, it works year goes, year come.....its a very strong relay, the 3 in 1 is also very good and strong
I had never seen, heard about or used this until today. To replace the original was going to cost over $100 from an appliance parts store locally. The original relay was burned to a crisp and I could not trust the capacitor! The rep there showed me the 3 in 1 but the price was $30. Still more than I wanted to pay. I bought it on Amazon for $10! Watched this video and viola, the refrigerator works again! I'm told this is what many techs use to repair fridges and that it may work 2 months or over a year! There's no way to really tell. I'm going to sell the fridge at a huge profit now, since I got it for free and thanks to the part and your video I don't have to scrap it for much less cash!
I'll give you 39 bucks
I love these 3 in 1 and leave them in place. They are a permanent fix. Never heard ever that they weren't a permanent fix. Go with it my man! Thx
Same here. The way I look at it, the compressor is short lived any way. Otherwise you wouldn't need the hard start.
I was curious, does the white wire always go to the left? My compressor has has the common prong at the bottom of the triangle, unlike the compressor in the video,,,
that stainless steel maytag behind you is the same unit that im having problem with now. the compressor would get real hot even with a new relay in place (parts store tested the cap good). i was going to install a hard start but changed my mind after watching your video. i'll save up instead and replace the compressor later. its a very nice fridge, i hate to just throw it away- im using the garage's fridge for now.
Is the fan running that's down by the compressor? Let me know.
Thanks Bill for another helpful video. I like the way you explain things.
Steven West not every compressor needs a run cap and the pins can also be for your condenser's fan.
Those Supco 3in1 are pretty strong. Its a bigger capacitor than OEM on most refrigerators. Some OEM replacement won't start a sluggish tired compressor ...but these will a lot of the times. You can leave on they're stronger than OEM
I sold tons of these at appliance parts. They fit most compressors especially the older ones where sometimes you cannot get the OEM part for it. These are great but they come in 2 sizes. 1.5th to 1/12th hp or a 1/4th to 1/3 rd hp. to keep em in stock we just kept mostly the 1/4th to 1/3rd because the price was no different. Nice video shows how tough these thangs are. It is good to have one in your tool kit. I keep a lamp cord on mine so i can tell if the compressor is shot and if it is maybe in defrost or has a short in the wiring to the compressor.
HI
I TEST IT AND GOT 3.6/14.4/22 .HOOKUP 3IN1 AND ALL WORK FINE...AFTER 4 WEEKS I CLEAN THE ALL FRIDG IN AND OUT AND WHEN I PLUG BACK THE POWER IT START ON OK THEN THE THE POWER BREAKER JUMP OFF
AFTER SOME TESTING I FOUND THAT THE MIDDEL LEG ON THE COMPRSOR IS SORTING= WITH TESTING ..I GET SHORT BETWIN THE MIDDEL LEG TO GROUND.
IF I PLUG THE POWER AND DON'T CONNECT THIS MIDDEL LEG....NO PROBLEM...ALL WORKS EXCEPT THE COMPRESOR...ANY IDEA WHAT TO DO NEXT
THIS IS SBS WHIERPOOL FRIDG.
CAN YOU ADVICE ANY
THANK YOU
How can you tell what your compressor’s hp rating is?
i have a 4.5cu” 2door mini fridge if that helps.
@@eds1942 I looked at the tag for the freezer on the back and saw it said 1.69 amps (ignored starting amps -- the capacitor helps with that I think). Then I went to this site www.inchcalculator.com/amps-to-horsepower-calculator/ to plug in the amps (leaving the assumptions about efficiency etc. as they were) - this gave me .22 HP (just a hair over 1/5) so I figured I could use the smaller of the 2 three-in-ones.
Luke S Thanks. My fridge has a different problem now though.
@@eds1942 its always something aint it? water and ice quit on grandmas big old frigidaire side by side.
Thanks Bill just ordered one for my soda Machine, hope it works.
Did you install it on your soda machine? If so, how’s it working?
Good job demonstrated with simplicity
Awesome! Another good video. You made the smoke come out!
I'm an appliance tech and I use these all the time. it's just a regular standard starter replacement. works like a charm
+Jack Lynch get yourself a 240 starter
+Jack Lynch yours will need a half horse power.
I put a 3 n 1 starter relay kit on my 6.6 Kenmore freezer cools good an runs fine , but won't kick off now. does this mean it's wired wrong or is the thermostat is bad
Does your fridge have a timer
no , just a turn knob thermostat on the side of freezer
Bill, Thanks for your easy to follow video on installing a Supco 3 n 1 Starter. My refrigerator is working like new. You are the greatest!
Thank so much for testing compressor and save money .
Supco is $22. My fridge relay (warranty recall) was $60. My freezer is $50. The supco replaces either, lasts longer, and yes can be left in place forever.
Make sure to check the three compressor terminals with an ohm meter to identify them if they are not labeled or on very old units.
My Whirlpool Side-by-Side refrigerator compressor stopped working after 7 years of operation. The relay on the compressor blew-out and I replaced it with a $7 hard start 3 in 1 capacitor rather than the $75 OEM compressor relay. That was 13 years ago and the hard start capacitor finally failed after refrigerator encountered some restricted airflow. It's now 20 years old and I'm hoping for another 10 years. Thanks for the video.
As a complete idiot who's never done an electrical thing in his life, this video helped me fix my fridge.
we all don't know it all brotha. all we can do is try are best
Same
would it work safer if you wired it into the overload.
Joel Hiltz - it comes with one, otherwise you would have 2 overloads
Just installed a 3 in 1. Took a chance, in that watching these videos on UA-cam makes you a little more adventurous in getting into a fix. Did make an assumption that the refer needed a start relay capacitor. Freezer was working but the other side appeared to be warmer than it should be. Opened the back plate and the fan wasn't working and the compressor was very hot. Got the original part out but the plastic parts of both items fused. Went to a local dealer and bought the 3 in 1 at his suggestion. $38.00. More costly than you said but if it works it is worth it. The part installed just as your video directed. It was easy. The only direction lacking was that one power wire is wire nutted to two orange wires and the other power wire is wired to one wire and it doesn't matter which power wire connects to either. The refer is making good sounds now and appears to be working properly. The operating sounds were not evident before the fix. Compressor fan was working now.
You mentioned that this fix is temporary. To me it is permanent. The next failure is a new refrigerator. I wish I discovered this video before the fix just for confidence sake. Glad I found it...thanks.
it wil last longer than the compressor etc will
I've had one of these 3 in 1 overload relays on my ages old chest freezer (early 80s) after the original part finally gave out and no OEM replacement could be found. It worked for over 10 years until yesterday morning when a thunderstorm kicked the power off twice. I know it's the relay that went because the compressor tries to run and the unit kicks on and then immediately clicks off again. I just ordered another 3 in 1 to replace the bad one. I've also had one of these 3 in 1 units on an upright freezer for about 5 years until the compressor itself died. I don't know why you would say the 3 in 1 relays are only meant to be temporary, they have served me well for many years.
hey Bill, nice video! I happened to leave one on for about 2 days on a refrigerator 1/3 hp and I had the correct 3 in 1 but for some reason it got hot and failed to keep compressor running. I believe something was wrong with compressor.
Thank you for your video, I was able to repair my appliance for $25 instead of replacing it!
How?
@@dds425 I bought that, and I only plugged it on my refrigerator. www.reliableparts.ca/product/inv_URCO410/474960. But I only used it to test if it can still work. After, I bought the real part, because the universal capacitor is not safe for long time usage.
Different refrigerator models use different oem components which can be hard to find or figure out which you need.
The 3 in 1 rco is universal. Just match the hp and voltage rating.
great video! thank you very very much.
I have a compressor that's tripping the breaker, I'll try just what you showed.
again, great video, thank yoou!!!!
We have been using the 3 in 1's on vending machines for many years. I also have one on my deep freeze. They have been running for years. Seems like a perm. fix to me.
Where do I plug the 2 power wires
@@Freud_Mayweather splice them into a heavy duty extension cord
Good stuff! Thank you!
Since they make these kits in three different HP ratings the RCO 210 - RCO 410 & RCO 810 you have to watch what the HP rating on the compressor your working on is, to make sure you are using the right kit...The RCO410 is for a 1/4hp to 1/3 hp...I have used these multiple times and have never had a problem...They'll do fine, if applied right...Still, a good video.
nice demonstration!!!
great job guys.
Great test. Thanks
Thanks for sharing 👍🏽
Hello, I'm in HVAC school right now and my electrical instructor told the class that I can't remember if it was him or a co worker but anyway someone installed a 3 n 1 and 10 years later when they where at that job again it was still working and unit was running just fine. So I guess they can last a while.
Chris Hvac Apprentice they do,like he showed the compressor will fail before the 3-1 does
NO BIG DEAL MY FACTORY CRAP LASTED 10 YEARS BEFORE GOING OUT LAST WEEK.
Glad they last, on mine the factory start relay is no longer available.
Last a while?
Had a 3 in 1 last 8 years. It was still working when I got rid of the refrigerator.
You were absolutely amazing! Worked for me
Great video bro! Thx
Thanks for the videos you share. I had learn a lot out it .
I have a frozen suction line right by the compressor. Any advice will be welcome and thank you in advance.
It’s probably overcharged,
the 3 in 1 will work perfect
Ashton Pollard h
Good to know, i enjoyed the video. and i was told that you can use the 3 in 1 as perminant.
If anyone is unsure of their compressor's HP rating (which is not always easy to track down), the Supco RCO210 (which may not have been available when this video was made) will work with all compressors from 1/12hp thru 1/2hp.
I've probably installed over 200 of the 410 and 810 relay, overload, and capacitor kits over the last 26 years. You do have to use the correct one for your compressor HP rating. All you did in that video is turn that compressor's windings into a crude heating element. You probably should have put a RCO810 on. It would have kicked out sooner, protecting the windings.
how do you know HP rating and which cap to use then?
Ok so I have a gibson upright 5hp which would you go with?
so jeff kreiger do not try to look for right or left, just for common start and run just know that black always goes on c and red always goes on r and white always goes on s on the terminals. they represent the windings inside the compressors
I've been doing vending for 35 years I've been using these quick starts about 10 when the common is below the other two instead of on top I used to look at it like it's upside down and I would put the red on the left instead of the red on the rite...... play some AC text at Johnstone Supply told me to I was put the red on the right since then these aren't lasting very long I've had these quick starts on machines for 10 years they've have failed and I replaced them with a new one and they still work I just did one Saturday
Thanks Christopher! That helps a lot
Tony check the Ohms.
I just installed one of these and it did bring back my old freezer to life! We are July 2022, I wonder if any of you installed one of these years ago and how long it did last. The OEM relay is around 80$ and I don't think it's worth it for my very very old Kenmore chest freewer.
great vid
Bill, I have watched all your compressor-related videos and they are extremely helpful - I think/hope you have saved me $800!! My repair guy didn't test the ohms, amps, or voltage of anything... he simply called LG to ask what he should replace, thats it - useless. Your the best, keep up the great videos! Thanks!
GOOD VID BILL
Hi Bill,
Ok had my fridge cooling sometimes then it would shut off, and all I could hear was a clicking noise every 1 or 2 minutes or so. Also, when I unplugged the fridge it did a last click, sort of like a reset.
So after watching your video, I decide to try the 3 n 1 starter...however I should mention that my fridge is a Kenmore (fairly old model) and when I got to the compressor which is a Embraco FGS 80A, the 3 pin connectors coming from the compressor were upside down from your compressor. Had to do a bit of research to find the common, start and run pins (in fact if you take the drawing on the 3 n 1 instructions and turn them upside down, your good to go and follow the upside down drawing for connections.
Installed the 3n1 and fridge has been purring since. I also noticed that the compressor seems to run noticeably cooler (still warm, but not hot) that it did before.
Thank you for your great video!
Raymond Dubé Awesome!
thanks I had the same problem Whit the pin order,
My fridge flooded thanks to Harvey here in Houston. The water rose 13in inside my house. FEMA, as some of you know, is being tight so I am trying to salvage my major appliances. I fixed my washer and dryer and luckily my stove wasn't damaged. My microwave is an over the range so the water went no where near it. As far as my dishwasher goes, everyone is telling me that is irreparable so now I'm trying to fix the the most important major appliance left, the fridge. It is a whirlpool side x side. I replaced the condenser fan motor (it was rusted and had mold from the flood) along with the the starter relay and capacitor connected to the compressor. The evaporator fan on the freezer side seems to work and thermostat switch is working too. ( I tested all with the multi-meter). The compressor, however, does not turn on, doesn't hum, or vibrate or get warm, nothing, nada, zilch. I'm getting continuity on the pins of the compressor like the videos say it should. However, when I used an amp meter tool that I bought, the cheapest I could find, I put it around one of the white wires that connects to the relay, and it is drawing 0.05Amps, that is it! When I disconnect these wires from the relay, and connect the power cord to the wall again, I get the same thing. This implies that no current is being drawn by the compressor. The other white wire and the red wire do not give any readings. I keep reading and watching videos to make sure that doesn't draw too many amps, but haven't heard anything about not drawing enough or none at all. My guess is that it isn't good either. So, now I came across this 3in1 kit which I should've tried first to save money. So folks, question is, iIs there anything you think I missed or is my compressor toast? If it is, I won't bother replacing it, might else well live on an office fridge and eat out some more until I can save for a replacement...but I'd rather not go there if there is still a chance to save it. Any help is appreciated.
Thank you I was able to fix my Frigidaire.
Thanks for sharing!
3 in 1 is good just for testing, just like you said, according to my tech they only last 90 days. very good video. very helpful.
Thanks for the Video. My freezer stopped working, compressor would not start. I replaced the relay switch and tested the run capacitor all tested good the freezer still would not start. installed the 3 in 1 and the freezer started up.
Thank you for your video
igloo freezer FRF 520 FM
i just replace working now😆😆😆
worked fine.........thanx
I've had to use them on older Refrigeration units with no info other then the comp horse power. ( make sure its sized correctly),
I have great success with them and checked the amps and temps every time I'm on site and she is just purring for a 20 year old refer unit. and for 11 to 20 bucks why not try it. Just make sure you ohmn out the terminals if they are not marked.
C to R will be the lowest # Example 2 ohmns
C to S will be the min # + 3 ohmns
R to S will equal the total of the lowest two numbers added up = 5 ohmns
hope that helps
Hey mr bill your video is amazing that only thing I didn’t get after we hooked the three wires to compressor the other two wire what did you wire them to?
They are hooked up to the two wires that plugged into the old start relay. (You'll first need to cut off the old connector).
Great info, I had one installed on my frig because it stopped working and that was back in 2007 and now for some reason my frig stopped working, and the frig is 19+ years old and worked like a champ. so I planning on testing the hard start to see if it is still good and then check the compressors. :)
Excellent
jeff kreiger black is always common red is always run and white is always start on refrigerator compressors.
Hi bill. does the 3 in 1 save the compressor from regulations in the voltage as the relay does?
3 in 1 is AMAZING. Leave it on. It will out last the factory start relay any day. The start relay has an little ceramic circle that bursts or breaks
Thank you, this video was very helpful and fixed my compressor problem ! .. for about a weeks time. I bought a 2nd capacitor, but now the compressor only clicks once when initially plugged in and no sort of effort to turn on. I used a volt meter to test the compressor and it seems to be reading fine. Any other suggestions?
Hello Bill, can a fridge relay be bad if there is no rattle to it ? Or do all relays rattle when they're bad as I 'm aware they have ceramic in them that seems to break into pieces. Thanx
U right bill 3 and 1 start relays I used two of those on two different refrigerator nice ones by the way and they both customers call me after 3 months t saying that the motor was gone find out that the motor is burn or out so u think u can start using those spp6 hard start relay?
good video...Great for the diy guy...I'm going to buy the kit tomorrow and see if my compressor is junk. Can't afford a $2000.00 fridge..or big repair bill
How did you make out?
+Bill Newberry put the 3 in 1 in it along with a fan and motor, and it's cooling like a boss now...Glad I saw your video...thanks again
itchyoldfart56 was your fan and motor bad as well?
yes, had to replace the motor and fan
center pin common, use ohmmeter on other 2 pins, pin with the highest resistance is the start winding!!! no big deal !!!!!
You're honest n that's good. My good sir that's really not the way to do it. U have start, run n common terminals to match with the diagram on the three in one. If that is wrongly done you'll damage your compressor. I'm an HVAC Technician so I understand your aim and I give u hi five for trying, however, when it comes to electricity it's either you get it right or wrong...and the wrong way has terrible consequences at times so I encourage you to read n understand what you're about to do next time. Peace n love always.
I wondered that also. My middle common is the low prong and his common is high prong. Does that mean I should switch the other two wires?
5 yrs and still running ... these 3 in 1's have proven their place as a cheaper alternative in appliances repair.
As with anything else, manufacturers will always recommend genuine o.e. parts even tho aftermarket can work just as good or even better than original.
RIP for this UA-camr Hero🙏 God Bless him whenever he is now…
So its only for test? I never know that you can check like that,thanks for the video
Hey Bill,
The URC0410 is the most common fridge Hard Start?
My OEM relay was clicking. Bought an OEM replacement relay/capacitor. That started clicking immediately. Compressor wouldn't run.
I measured the compressor pins and got 5, 3.9, 8.7-8.9. I also scratched the housing and tested each pin. No beep. So, am I to assume the compressor is still good and that the replacement relay I bought was bad?
I'd like to try a Hard Start and see how that goes. Just want to confirm the 0410 is the correct Hard Start model.
Yes you can live it on The refrigerador compresor is whit a resistance to do not burn And it going to work perfect long time its a chip way
LEAVE
Thanks for this video .
My fridge when I plug in the wire the fridge light inside the fridge working but the fridge compressor and the little cooling fan the one next to the copmressoer not running ?
hey bill,just a comment on the 3in1 capacitor,make sure you Always discharge the capacitor to ground before installing it,it is a power resevoir and you can get a nasty shock if its got stored electrical energy, a standard a/c unit for the home uses a capacitor to start so i dont see why you could not use one of those permanently instead of the costly relay from the mfr. a start capacitor for a whole home ac compressor is usually no more than 30-40 bucks,the fact that that compressor had a big divot on its top was indicitive that it was dropped also.
because those are run caps.. this is just a start cap, a start relay.
Add a thermal overload switch connected to the case of the compressor so if it get hot it will turn off. Adds thermal protection to the supco.
thank you very much
My hunch is the compressor is either jammed(like the piston assembly dislocated) or the run winding is open. The 3in1 is just another relay/capacitor/overload so its good as any other 'OEM product' if of the correct rating.
The one on the fridge I'm fixing now had one for 10 years and finally went out.
thank you
i am going to install one of these. on the two black power wires does it matter how you connect them to the power cord? any combination ok?
nice vid where would you buy 1 of those 3in 1 would lows have that or home depot ??
Usually when you need to use the 3&1/hardstart, it usually means the compressor is on its way out. It can last 3 minutes or 3 months. Sometimes the 3&1/hardstart can be wired to the original capacitor that is on the relay. Just splice the run and start wires and connect it to the capacitor and then connect them to the compressor terminals. That will make it start faster. I seen that method done a few times.
Unless the old relay is just plain bad and needed replaced. But like you said, it will start a compressor that is going out.
Thanks for Watching and Thanks for the Comment!
It has nothing to do with a “ goin out compressor “. The starter and relay have no rela
@@frankarchuleta5427 If not, then something may be causing that compressor to run hot enough to cut off into thermal overload. If you have a compressor running excessively hot because the capacitor lost about 15-20% of it's value. Now you pop out the cap from the relay and replace it with a new cap. It will start up and then in about a few seconds.."CLICK" and again, the overload cut the compressor off. Now, install the 3N1 with the cap and it will start, no problem. The compressor will draw less amps and at the same time, begin to cool down while its running. Keeping the condenser clean helps.
The capacitor only has an effect on the start coils, which are only energized during startup and are de-energized once the motor has reached full speed (
@@xxetniesxx I know how a compressor works. What you're telling me is useless in the field. I check the amperage on startup, I use a cap tester and check for the correct number of microfarads, if not, replace the cap. I check resistance on the start winding and the run winding. If there is continuity in both windings, I just change the cap and it works. But if the amperage draw is excessive, I'll add a hard start. A compressor is only a hermetically sealed motor. I've seen stacked caps on A/C compressors, and you don't see that much since they have double capacitors. I'm well aware how a capacitor works. I'm not running a school here. I appreciate your input. But please, don't question my knowledge. All that I learned in trade school 30 years ago. In the field, if it starts, it gets cold, good enough. If it doesn't work after all testing, change it out. No one in the field is going to dissect a hermetically sealed compressor. Furthermore, there is a big difference between a battery and a capacitor in that a battery turns chemical energy into electrical energy whereas, a capacitor stores electrical energy that is quickly discharged. Thanks for your input.
Silly me. There is a plethora of sources on line for the 3 in 1s. Question now is which model number is most appropriate or does it make a difference. I was looking for the RCO410 that showed up in a video. Your preference?
been using these for 27 years
I have installed hard start Air condition capacitors on refrigerators that have a start capacitor and they work for years after
how do you do it? most only hav two wires?
you need a start relay to get the compressore started or you can just jump the terminals on the start winding with a 4 ohm resister like i do on mine , just flip the switch for a second and the start winding is energized then flip the switch off after the compressor starts
how many watts resistor?
hi bill, I don't agree with not leaving on the 3 n 1, as a maintenance tech/electrician/hvac, this component is called a hard start ,,,, frigs and a/c,,,, I have installed 100's of these, over many yrs,,, never had a problem. Your video is right on target except the hard start, in my appended and others in the field. thanks have a great day. marvin
+M L Dickinson Thanks for the Comment! I've mainly used them as a testing device, I have in some cases left them on without any issues. If a compressor is good, there shouldn't be any issue. Thanks for watching!
if no diaphragm how can we tell what wires go to each of the 3 pins on compressor my hard starts do not have a diaphragm on them so how can I tell were exactly my red white and black wires go on the pins coming from compressor
+kurtis bardin it is usually the case that the common is on the top, run terminal on the right and start terminal on the left. but not always!
If I'm not mistaken the start terminal would be the terminal that the PTC (t.e. Klixon 4TM) is connected to. So find the PTC terminal and this is your start terminal. Another way is find the two terminals that read the highest resistance and these two terminals are the run and start terminal while the unused one is the common terminal. Now measure the two resistance from the run/start terminals to common and the higher resistance reading would be from the start to common and the lower resistance from run to common.
C is common and black wire. R is red and Run wire. white is Start
Hello Sir. Great video. So, I'm trying to do something I probably shouldn't. Run a mini fridge on a 1000w pure sine wave inverter. It actually runs but when the compressor kicks in the inverter beeps... over volt I'm guessing... and then it doesn't trip but continues. I would love to get rid of that beeping. I could get a 2000 w inverter but I really don't have the space. I managed to get my Window AC to run on a 1000w Yamaha generator by ADDING a Supco (hard start) in addition to the existing Capacitor. Wondering if I could do the same here...Add the supco to the mini fridge (or should I replace it.) or am I crazy?
Hey John. Could you show or explain how you wired your 3in1 to your existing capacitor? Thanks
Hey bill just put a 3 in 1 on my whirlpool wasnt sure if the compressor was good so didnt want to spend alot but the parts dealer told me that the servive techs were using these instead of the original parts. Do you have any idea how long they last?
Hey there great tutorial, I installed it and it works well , I was not able to mount it upright so I laid it on its side , is there any issue with that?
Hey Bill, can you say something about what the freezer sounds like with no start relay? Does the compressor still "hum" and can you tell the difference between humming and actually running?
