How To Check HVAC Capacitor With Multimeter

How to check a capacitor in a HVAC condenser unit using a multimeter to see if it is weak or bad and needs to be replaced. Even though an air conditioner unit will likely still run with a dual capacitor that is out of range, but the longer it operates like that, the more it's lifespan will decrease. Of course how far out of range will make a big difference as well. A 40 MFD capacitor that is reading 30 MFD, will likely still work but the AC compressor will have a harder time starting up. Whereas a 40 MFD capacitor that is reading 20 MFD, may not start at all.

Thank you for all your generosity to homeowners that are so appreciative of your easy to understand instructions on how to keep our HVAC in such a great working condition! I can’t thank you enough!

[joshuaag]

You saved me a lot of money already. First, it was my cap and so I replaced it myself. A month later, it was my fan motor, like today, I replaced it myself too. For quick calculation, if it is + or - 6%, just multiply the MFD by 1.06 or 0.94 and you'll get your MFD right away. Thanks you for helping me save some money.

New to HVAC and an Apprentice I am. I really want to thank you for taking the time to simplify this matter determining of a good vs bad capacitor. Much appreciated 🙏

[fredi]

Thanks so much for your video. I was able to diagnose my ac problem and found out that the run capacitor was bad. Ordered next day delivery and I have my AC fixed next day. I really really appreciate your help. Keep up the good work and god bless you.

Love your videos & keep up the good work! Here's a helpful tip with the calculator to save steps/time. Instead of putting in the extra numbers in parentheses, just type in 35+6% or 35-6% on the calculator to get the microfarad range. Makes life much easier! 😀

This is the best #1 channel for Hvac on YouTube

Just want to say thanks for this. My blower motor inside was whirring but not running and this helped me figure out how to test the capacitors. I spent $50 on a clamping multimeter which I'll keep for next time and $12 on the capacitor that needed to be replaced and that wouldn't even have covered the callout for anyone else. Saved me a fortune.

Thanks for the explanation as to if it would run if out of range, and how it affects other components. My 45 was reading about 12. It was running, but I’m sure near its end of life. Florida, so our systems work pretty hard. Better safe than sorry.

[JazzLowrider]

Thank you for the easy informative explanation, I wish I had a teacher like you, all your instructional videos are just great.

[uptownphotography]

Great video it helping me in my hvac school training your explanation is the best you consider teaching hvac in classroom if you not a teacher love channel man.

[tedlahm]

Clear concise information. Even the math lesson was well appreciated.
Thank you.

[bluebutterfly]

Thanks for sharing your very informative video and for showing your lovely garden, may God bless you

[KhanGirey]

Thanks, this helped me identify a bad capacitor. Hopefully the replacement I ordered will have fixed my issue.
For those reading, make sure your readout is in the correct units. My fan was reading at 4.8uF, but the HERM was reading out at 89nF. (this lead to a lot of headscratching as I was reading it at uF).

[dumptrump]

Thanks for great information. Checked my capacitor because it would start air conditioner sometimes and sometimes it won't start .my capacitor was below minimum and fan side was below 1 .fires right up with new one.thanks again for your videos
