Run the Turbo 200s. Universal motor-run & the mini universal fan motor-run caps. Made in USA. Good warranty. Pass the cost on to end customer. Simplify stocking.
I have transitioned my van stock to primarily Turbo 200’s in all three sizes. So much simpler and I never need to run to a parts house because I don’t have the right cap.
Formula for capacitors are: In Parallel increase capacitance C = C1 + C2, and In Series decrease capacitance 1/C = 1/C1 + 1/C2. Example 1/5 + 1/7.5 = 0.2 + 0.13333333 = 0.3333333333 and 1 over this gives 3 MFD.
For you homeowners watching, every spring, test the capacitors in the condenser and furnace and keep one of each your system uses on the shelf Change the filters every two months , clean the condenser coil every spring, keep plants away from the condenser, install a 5-2-1 hard start kit in the condenser and a surge protector on the disconnect switch. If you do these things, you may never need a service call.
AmRad's seem to be the best caps on the market right now, made here in the states. Their "Turbo" universal dual caps are pricier, but can be wired to accomodate nearly all of the MFD ratings on motors, it eliminates the neeed to stock your truck with all of the individual dual run sizes, especially if you have a small truck/van that doesn't have a lot of room. In the event you run into a unit with an uncommon rating such as a 40/10 or a 35/7.5, as Craig said you'll be able to get the customer up and running. I also like the CPT (compressor protector terminal) feature AmRad has that works good with hard start kits, in the event the potential relay fails to take the HSK out of the circuit when the compressor starts, this feature will blow open like a fuse and save the compressor.
Do not use titan caps what so ever. Unless you want to go back and change them every single year. Mars premium caps or turbo 200s. That’s all I’ll ever use. If I even see a titan I change it out because there fail rate is that bad.
Cause they're built so cheap. Dual cap is only like $5. Company I work for buys titan cause they're so cheap to maximize profit. But I guess they want to kill customers motors...
Not true yes they are inferior quality compared to the titan pro or armad caps but I’ve installed ones on systems and they last just as long as manufacturers cap i means it’s multiple variables that can cause a capacitor to fail besides build quality. Now I do install and recommend amrad or titan pro caps but I give the customer the option of paying a lesser amount for a capacitor that comes with a weak warranty vs the other ones that comes with a 5 year. That’s like saying the cap is bad because of the brand and the new one you put in that’s a better brand will not fail and you come back a year later because it was something else causing that cap to fail
The capacitor reactance[ohms] is figured 1/(2*3.14[pi]*60[hertz]*farads. or 1/(377*farads) Microfarads is Farads*10^-6. i.e. 5mf capacitor = 1/(377*.000005)=530 ohms Xc so if you connect a 5mf capacitor across a 120V 60Hz AC source, it will draw 230ma 120V/530ohm=.230amp. Since the current and voltage are out of phase, it will consume no power…therefore 120V*.230A or 27.6VA.
They're two different things. Amperes are a measure of electrical current flow, but pressure is a mechanical measurement. Turning electrical power (amps times volts) into pressure and flow is pretty complex, and depends on the efficiency and design of the compressor. Does that help at all?
Question. I monitor our home's wattage with a Sense unit. My A/C was ruining smoothly, ie. the wattage was flat and smooth and unwavering. The capacitor failed, and a the tech replaced it and the A/C runs again. However I noticed the Wattage meter is reading a fluctuation in current then the A/C is running now. It fluctuates as much as 1,100 watts now. The tech came back out to check with amp meter and said it was within specs. Is this an issue? What would cause this, wrong sized capacitor? Thanks.
I had a similar issue, my HVAC tech installed a 55/5, but after some research I found it should have been 50/7.5, everything seems to be working fine even after a couple of years, but my capacitor just went out the other day so I got this new one and replaced it with the correct one, want to see how long this one lasts?!
Remember, you can put a 5 and a 7.5 µF capacitor in series to make a 3 µF capacitor. Of course you need to have room to install two capacitors, wrap them up and secure them properly.
Capacitor mfr make what equipment mfr needs. More efficient outdoor fan motors use 7.5 instead of 5, so now we stock dual caps with 7.5. It was not necessary 25 yrs ago for residential anyway.
Dear all,I have a question which capacitor should be used when there is no detail on capacitor that the burn,so does anyone have the formula please suggest me ,I asked everyone but no one has a proper answer
I have a 4 ton two speed compressor that quit a few days ago in the extreme heat wave in N. TX. A few months prior, I took off the service cover on the condensor to see what cap it had so I could buy one as a backup, while waiting for what could be hours to a day or more for a service tech. I was *very surprised to see a **_30 / 5 µF dual run capacitor_** as the only one in the cabinet* The bad one tested 17.4 on the Herm, so I knew it was bad. Grabbed my spare and was back in business in 15 minutes or less. LRA is 105 amp, but drops to 11.5 Amp (on the low speed) running after startup. Thus, why would such a large unit only need a 30 µF run / 5µF fan CAP?
Tell us what the make and exact model off the label of your AC outdoor condenser. I will lookup the proper capacitor from the factory. I wouldn't be surprised if it should be a 45/5 or 40/5. But anything is possible.

My last comment I said that my run capacitor failed. I got it replaced and the air conditioner works again, but that's not the end of the story. The capacitor that failed was NOT the original one that came with the air conditioner. How do I know? The failed capacitor was a 55/5 MFD capacitor. After some research, I found out that my air conditioner was only rated for a 35/5 MFD capacitor.🤦🤦🤦
@@Franklinveterinarycenter1of4 Yes. I did, but only after I looked online and saw that the capacitor was rated for 35 microfarads and I'm like wait a minute, the capacitor's been oversized this whole time?! Two takeaways: First, now I'm glad that the capacitor went out, or else I wouldn't know that. Second, I'm surprised that the compressor didn't burn out, especially since it's a 20 year old unit.
@@eric01406This is not to imply bigger is better, because a capacitor that is too large can cause energy consumption to rise. In both instances, be it too large or too small, the life of the motor will be shortened due to overheated motor windings.
I've had to change 370/440 45/5 dual run capacitor 2 times 1st it lasted a month 2nd time it lasted a week I checked windings for both the compressor and cfm which tested fine both times and amp draws were both within range of the data plate. Condenser coil is clean and cfm bearings are good spin freely What's something that I am missing or not checking resulting in the capacitors going out?
If you have repeated capacitor failures annually and you’re buying good quality capacitors that cost $15 or more, then you might have a compressor going bad.
@@USA-GreedyMenOfNoIntegrity That's what I'm thinking too both times I replace the capacitor they were completely dead. I've noticed that on the top shell on the compressor showed signs of overheating. For context this very same unit had a leak at the high pressure switch which blew out the charge I repaired and charged it accordingly. The only thing I haven't done yet was an insulation test, but since I replaced that capacitor customer hasn't called back since.
If you put the same brand cap in you may have just gotten a bad batch of capacitors. Of course, make sure you are not using a start capacitor in place of a run capacitor. Using a start capacitor in place of a run capacitor will fail.
Maybe capacitors made 30 to 40 years ago. I haven’t seen any capacitors made in the last 20 years that will outlast the unit. And yes, I’ve had to go back and replace Amrad capacitors after 5 to 7 years.
Craig is an absolute legend in our field. Keep up the great work! 👊🏽💪🏽
Thanks for video. One of the techs with best teaching ability in the biz IMO
Thank you, I was wondering this and magically just popped up in my feed, awesome!
Run the Turbo 200s. Universal motor-run & the mini universal fan motor-run caps. Made in USA. Good warranty. Pass the cost on to end customer. Simplify stocking.
That’s what I do, most likely you will change the unit before the capacitor again.
I have transitioned my van stock to primarily Turbo 200’s in all three sizes. So much simpler and I never need to run to a parts house because I don’t have the right cap.
I’ve seen older lennox units blower motors using 40mfd capacitors crazy

Amrad's are a solid choice
also, remember the relationship to know how the power of the capacitor affects the changes in voltage or frequency of the nominal design. Q1/V1=Q2/V2.
Thank you for sharing!
My pleasure!

The Titan Pro caps are total junk. Might get a year or two out of them.
Thank you! I haven't had a chance to deal with them since they came out. Good to know.
I work for a company called Marr’s and new techs thought we had our own capacitors as a company
The capacitor reactance[ohms] is figured 1/(2*3.14[pi]*60[hertz]*farads.
or 1/(377*farads)
Microfarads is Farads*10^-6.
i.e. 5mf capacitor = 1/(377*.000005)=530 ohms Xc
so if you connect a 5mf capacitor across a 120V 60Hz AC source, it will draw 230ma

Nice this one answered my question
excellent video and class. Please in the next video, Can you explain the relationship between amp vs pressure?
They're two different things. Amperes are a measure of electrical current flow, but pressure is a mechanical measurement.
Turning electrical power (amps times volts) into pressure and flow is pretty complex, and depends on the efficiency and design of the compressor.
Does that help at all?
I’m curious too which brand you think is the best or last the longest?
Most techs like the USA made ones, like the AmRad.

C1 X C2/ C1 + C2 = capacitor when wired in series@@theprofessor5584
Craig what causes a sweaty blower cage. I see water drops and condensation underneath the snail.
Good job
I just wish the turbo 200 wasn't like $80
Great video!
Can I use a dual run in place of my single run on my air handler?
General question for anyone: Do manufacturers pair compressors & fans with capacitors to avoid going much larger on those components?
Capacitor mfr make what equipment mfr needs. More efficient outdoor fan motors use 7.5 instead of 5, so now we stock dual caps with 7.5. It was not necessary 25 yrs ago for residential anyway.
Which brand do you recommend?
Is Amrad any better?
Mars premium caps!
I've had 3 or 4 bad Mars capacitors in a row. I'd recommend something else.

You can have an higher rating just don’t go lower so don’t stock a 40/5 just stock the 40/7.5 and it can be used with the 40/5 and so on.
The larger metal with higher rated voltage and BETTER QUALITY will probably last to the next century.
If the homeowner changes the filter regularly 😅
