Do you have any promo codes?
10:21 when you test the resistance, doyou test a specific probes or all 3 should work ? For me Only one is showing resistance/continuity, the 2 others aren't
Thankyou shwring gues good welcome gues
Thankyou gues all shering
Brother I am BLOWN AWAY by the knowledge you shared in this video !!! I am retired HVACR tech and no way could I have explained everything the way you do here. Awesome job !
great teacher! clear and detailed photos and explanations. I am an old DYI guy playing and learning how to fix the AC on our camper van. I learned from this video the importance of changing all capacitors and relays at once. I worked my way one by one and have ended up with a problem again, probably a new capacitor blown.
Thank you so much for this fine and informative video! My fridge has one of the modules with the built in control board, and it failed last. Thanks to you, I was able to isolate the probable issue and swap out the part myself. Up and running, saved a lot of $$ and maintained social distancing.The new trifecta!
Today I changed burnt PTC Thermistor in my Samsung fridge. Your instructions mentioned to check the resistance between starter and running inputs (bottom two out of total three)of PTC. It should not be open. Guess what! Mine was open. Along with other tests I decided to chagned PTC for $15.00 from Grainger. It worked. Thank you very much for a very good explanation.
I own a food establishment and do my own refrigeration maintenance. Note that I am properly equipped and EPA certified to do so. This is an excellent video!
Thanks a lot Jean!
thank you for the very informative video sir, I myself am a hvac and appliance tech of 20+ years and you might have schooled me on a thing or two in this video.
always wondered why overloads failed now I know. I can honestly say I have never taken the time to take one apart and look at it.
God Bless UA-camrs like you who share knowledge helping the average fellow diagnose problems like these. Very clear, very kind of you.
I have a 17 year old mini fridge that recently stopped cooling. Upon plugging it in, the compressor would hum for a few seconds and then the overload would click and trip open. Checked the protector, very low ohms. Checked the start relay, completely open. No rattles, but when I took off the cover the disc and contacts looked pretty bad. Wanting to make sure a new start relay was the right fix, I made a jumper for the start relay pins, and then plugged in the fridge just for 1-2 seconds and unplugged it, and the compressor started up and sounded normal. After watching your video and the troubleshooting I feel confident enough to order a new start relay. Thank you for sharing.
Fantastic tutorial - with just my basic air conditioning training and your explanation of the components I was able to diagnose my 1970's Coldspot refrigerator - thanks for showing some of those vintage components, it really helped my comfort level!
Recently had a Frigidaire mini-fridge that wasn't cooling. Compressor was hot and when the thermal overload reset, it was pilling 9 amps with an LRA of 11. I checked the PTC and it was reading about 50 ohms. I disassembled it and found signs of carbon/overheating on the run terminal/PTC contact surfaces. I scraped both surfaces down and got a reading of 9 ohms. I reinstalled it and the fridge started up with 1.3 amps while running. It continued working while I awaited arrival of the $10 replacement. It's running fine. Thanks for the great video which I found after I had repaired the fridge.
I can’t thank you enough, I’ve watched and currently watch a few hvac channels, you are my favourite
That was a great demonstration of the different relays and caps for a domestic refer can. Thank you for the video. And most of all HVAC ON AMERICA!!!
Thanks a lot Ray Ray!
Also as always thanks so much for the detailed information. I can always tell you take pride in what you do. I hope when my apprenticeships are over I can afford to repay you for you're help.
Thank you very much and hey just tell others about the channel and the book, pass the word, thanks a lot Daniel!
@@acservicetechchannel definitely will. It's the least I can do.
This is by far the most valuable video on relay fault finding on the web. Your instructions are the best and most easy to understand. Well done and thank you for sharing with all of us.
Excellent explanation- really appreciate your sharing. Keep up the great work!
There's "PTec" units in the hotel I work at (old I know 😂), this was super helpful! Thanks man
Wow, tons of information. I did see my relay and capacitor set up. I have a craftsman digital meter that I use for small engine wiring. Not to sure about setting up for ohms on mine to accommodate to test these pieces. I've been out of a refrigerator since Wednesday
Clixon in the refrigerator .. Thank you, God bless you, my dear
A truly magnificent, very helpful video, and information. Thx
Glad it was helpful!
Great tutorial! Very clear explanations. Super helpfull my friend! 👍👍👍
Really helpful! Thanks for sharing 👍
Excellent video - just what I was looking for thanks for sharing.
Awesome, thanks Mark!
Awesome demonstration, thank you.
Thank you for your support!
Found overload protection was open on my mini fridge insignia 2.6 cf ... In Dallas lots of lighting occurred maybe jolted it.. Worth trying it for 5 bugs .. Ordered it will see.. Many thanks for your video
Great job and video Craig
Thanks Kenny!
I think I'll grab the paper back. Great video.
I had to subscribe bro. You are good, please keep doing what you do. Following you here in Kenya.
Thanks for the sub
Excellent & good teaching...👍🏽 ⭐️⭐️⭐️⭐️⭐️
Glad you liked it!
Thank you so much, that was very helpful and well explained
Glad it was helpful!
This is very helpful, great video.. thank you
Thanks for your help and advice on how to do trouble shooting
Lol. You said tale a picture. Cool. When I started doing this in 1978 we had to make a drawing. I watch your videos review and try and get my wana be techs watch them.
My first year teaching, I told the student to take a sharpie and write the terminal letters on the unit before disconnecting or draw a picture on a piece of paper. He looked at me with an odd look on his face as he slowly pulled out his phone to take a picture, ha ha!
Excellent video partner thank you for sharing!!!!!!!
Thanks Jimbola77!
Very helpful, thanks for posting.
Glad it was helpful!
This helped me fix a midea freezer that was DOA. All the parts tested out fine but i noticed the connection to the relay was very loose so I tightened up the connector and the compressor started humming along!
Thank you. All the way from South Africa
I noted that there was no thankyou sent for you from Craig. Maybe because you are from South Africa (like myself) and they probably think we are still swinging in trees here like Trump ha implied. Lol
great video this help me repair my freezer
You the best teacher ❤️
Thanks so much JD!
It's a nice video and I have learnt a lot.
Awesome video! Thank you.
Tetorial overload dan kompresor yg sangat keren ....mantap
Great video to save for future. Thanks for taking the time to make it and share. Do you know if there is a good cross-reference source for components in case they no longer make the exact model component. Also, any comments about using the universal 3in1 components you can get online?
Thanks for sharing great information my just stop working freezer and refrigerator.
Hey Craig I’m thinking abt buying your book! Are you planning to write another book for more advanced techs? Where we learn more about theses relays and and Hvac wiring ect and more complicated Hvac situations that we might encountered, but regarles i think 💭 I need to have your book handy with me everywhere that I go until I feel confident enough. Thank you for sharing your personal experiences you make us better!
I would like to put together a book on electrical and furnaces. However it all takes a lot of time to get it all exactly how I want it, thanks and please let me know what you think of the existing book after reading it. Thanks!
Another great video!
Thanks Familia Sanchez HVAC. You have been around commenting since the start! Thanks!
Great information and clear
Glad it was helpful!
Love the explanation
Glad it was helpful!
This was very informative keep up sir and share with us it wil help in the future👍👍👍👍
So nice of you
Thank you sir. I learned a lot.
Glad to help!
You are the best of the best.
thank you..for telling me how to check the refrigerator components.
Excellent video, congratulations
Thank you!
is it possible to measure resistance reading between the start and run winding of the overload protector & PTC relay combination kit?
Very nice video, thank you.
Thanks DC!
Great video and great details!!!! But what to do if one of the three leads coming off the compressor or lose? Can it can fixed or does the compressor needs to be replaced? The other two or fine but that lead is lose with a hole around it.
Wow Beautiful info thank you so much
Hi pal, that is a very good work!!!!!
Thanks for the visit
Very nice video. Thanks
Thanks Lance!
Great video, you are the real deal
I appreciate that!
I'm hoping someday you'll put all these videos on CD or flash. I would buy it just to watch it at hotel or away from home. I saw your "video-book" but it linked to youtube which is useless in hotel because of the slow internet. BTW, study guide and quick cards I ordered from your web site are really kool. Thank you.
Great video, Thank you! Is not UF is Miu F, is a Greek M, used to indicate MIcrofarads.
Thank you for this miniclass!
Thank you sir. I'll be buying products off your amazon shop.
Thanks a lot Earth is hEart, I really appreciate it!
Good
Great video...!!
What a awesome video.
My Kenmore Elite (Whirlpool) refrigerator stopped working when it was about 5 year old. I took the start relay off and shook it and it rattled like a maracca! Got a new one from the parts store and it hasn't failed since (15 years). Had other issues with the fan and ice maker and water in the door though.
Nice teaching
Glad you enjoyed it!
Your video helped me diagnose a friends mini freezer with a broken PTC starter. I can't find an exact replacement anywhere on the web. Can I pull the PTC off another broken freezer even if the resistance is slightly different? My friends broken one is rated at 4.7Ohms and my working one is rated at 6.8Ohms. Is it safe to switch? Thanks.
Thanks that's amazing great video channel I like this post Nice I dea I respect
Cool video. I ask are all these fridge or freezer compressors for commercial refrigeration?
Thankyou brother that's the best explanation 👍👍❤
You're most welcome
Great helpful video, my question is if I check everything work but the compressor overload keep tripping please advice.
Question, My compressor cane with two types, the pin config is the same as the third compressor in your first illustration, but has the pc thermistor and overload protector attached, but also came with the third version with the start capacitor, on the side of the compressor says no start without starting device, I love you book and videos, always wanted to learn about this, Ty, Anthony
Very nice video good information thanks but I have a compressor star some time and it gives hard start some time
Great job and video. Now i am not sure what to do. Working on a wine cooler. The reading are E1 E1 DUAL COOLER. Fuse is good. Start relay ohms is .1 overload relay is 4.7? what do you think?
Nice Tutorial , thx lot dear
Glad you liked it
Great stuff as usual. Can you do a video on replacing these with a supco 3 in 1?
I'm starting to thing my compressor may be mechanically stuck as I have replaced the relay/protector circuit, the run capacitor tested fine and all electrical readings on the compressor are exactly at spec from the datasheet. My condenser fan was making a loud racket, so I inspected and cleaned under the fridge from the front only, which stopped the noise, apparently by stopping the fan, because an hour or so later I noticed a puddle from the ice dispenser. The compressor was extremely warm. When I tested the protection circuit I got and am still getting .1 ohm, then 0, with 3 different meters and 2 sets of probes, so for $36 I replaced, but compressor still won't start(tested the new one also, reading didn't fluctuate). So, any ways to unstuck a compressor? I'm thinking about trying a heat gun, but this is not my area of expertise.
Excellent training.7/11/2021
Glad you think so!
Thanks for the vid
Any time!
What about a solid state device in place of the thermistor? I was checking a refrigerator for my home and found a tiny circuit board in the start up plastic shell that plugged into the compressor.
Does the Start Capacitor and Relay have any effect on the fridge freezer not shutting off?
I already changed my thermostat for a brand new one so am now thinking that it could be a bad start cap or a faulty switch that is permanently on inside the relay.
Note that mine has no control boards etc just a simple mechanical thermostat a Hotpoint RFAA52P.
@9:00 those capacitors I’m fairly certain were run capacitors. Their mfd ratings are low. Even supco has kits that identify these as run capacitors not start caps. Still a great video!
Yes absolutely are run caps on the TSD's thanks and good catch!
Good sir. Thank you.
So nice of you
Good video!
Thanks a lot!
where can i find some of these parts. i am looking for a ptc for my air dryer online and i cannot seem to find one
What a great video
You are so kind
Hi from the overload terminal to ground I got a reading of 115v however from the relay terminal to ground im not getting any reading is that normal or should I be getting a reading of 115v aswell?
My compressor protector (the gray one) it reads around 10. that's mean it's time to replace? Is this effecting the compressor? My compressor hot and is not running, lost cooling a day ago, try to figure out whats the problem. I tested the compressor with the ohm meter, seem like it's good.
The capacitor in the third one from left is start capacitor or run capacitor? Thank you
I just checked 3 in 1 Supco RCO 410 capacitance which is 243-292MFD. I watched videos and found a lot of people used this to replace the original 15 MFD. Will it be bad for compressor? Thank you
Thank you very much, my GE got a relay starter bad. 25$ @ at Amazon, i will replace it.
Thank you for posting this very informative video,,,My question to you is what caused the compressor in my wine fridge to stop running and get very hot,,,Initially it stopped working and I replaced the overload protector(6750c-0004r) and start/run relay(PTC starter relay( P6R8MC) ,that didn't solve the problem so upon testing the thermostat I found it bad,so I got it to run after replacing the thermostat(18GLB020008) and that's when after running for awhile the compressor got very hot and I noticed a strange smell.,,I'm wondering if maybe it developed a refrigerant leak after moving things around like the condenser /evaporator,Thanks in advance
Hi, I did all the tests shown here and on the compressor. It leads to the relay but I hear it clicking on after I pull it in. Can the circuit board still cause the compressor to not engage? I don't hear a second click for over draw. How would you know or could it be low on freon?
I got a ratteling sound comming from the overload unit when I shake it after removing it. Got a new one but it rattles to like the old one. Is this normal or does this mean its bad? Been trying to prevent a surging problem I was having with my new Daewoo mini fridge. Causes a slight trip in the circut its plugged into.
Hi there, I have a Sub-zero 511 from 1991. Yes, it’s still running and I am trying to keep it that way. The freezer stopped working and I found that I have an issue with the freezer start relay. I opened it up and rotated the ptc thermistor disc and it is running again. I cannot find a replacement anywhere. Do you know some of these start relays are interchangeable? Thanks for your very informative videos!
Craig this is great video explaining these start components. I greatly appreciate all of your videos. I have a question. I work at a facility doing the HVAC throughout the buildings. Just installed a new thermostat on an old Traulsen reach in fridge. It's over 30 years old. runs great now. After watching this video and another about currect relays I am considering getting new start components for this Traulsen. Would that be the proactive right thing to do? The parts for the Tecumseh compressor can be gotten locally for under $50. Your thoughts?

Thanks.
Can you send a link on the last one with the resistor
