I had to buy a new multimeter to read capacitance since the one I had (which I thought was a decent Klein one) didn't have it.

It's also handy to find out what type of capacitor your system uses and buy one to keep on hand. Capacitors always seem to go out on the hottest day of the year and always on a weekend.

very helpful having the same problem thanks man!

[thereddeath]

Leaving a comment as a token of my THANKS. This was exactly the information that I needed. Really apprecaite the quality content sir!

Man, you saved my 111 degrees Arizona summer. You a hero

This video just saved me $500! I had an appointment to have an HVAC person over tomorrow that would have cost $350 for a diagnostic, and the repair would have been a week later for another $200. Tanks to this video, I was able to fix my unit the same day it stopped working (and it only cost me a $30 capacitor). THANK YOU!!!!

Since you covered the label on the new capacitor with those straps, it's a good idea to use a marker and write the value in plain sight ... 40-5. I usually date it too.

Why bother testing the capacitor just get a new one specially if your old one has been there for a few years…the problem is when you replace your capacitor and your ac is running but not cooling…so what now? Clean the line that runs from the unit inside the house…still no cold air….now wash with clear water the fins in the outside unit…still no cold air….

Someone tried to charge me $1900 just now to do this. Unbelievable and it’s criminal!

[gordonlee]

Thanks, this was very helpful! Solved my issue for about $30. Found the part in stock at Ace HW. For anyone who was wondering what multimeter setting to use for checking residual voltage, it's DC voltage. Cheap DMMs won't have a capacitance meter, unfortunately, but if the symptoms are fan blowing but not cooling.. and no fault nessage on the panel, good chance it's the cap.

[TopRival]

You really glossed over how to drain the charge from the capacitor with the screwdriver. That sounds like a dangerous step.

[czluver]

Even though you pulled the disconnect, you should also 1) set the AC to off via the thermostat, 2) set circuit breakers to off, and 3) still check that there is no voltage at the contactor. Also wear safety glasses. If the capacitor shorted out from having a charge sending a spark, well, that's a small piece of metal sent flying.

Busted caps are the most common cause for no cooling. If there is even the slightest bulge on the top of it, it is failing. Check your AC TODAY and get a spare one (<$20). They only go bad on the hottest days (most usage) and frequently on the weekend (most usage). This preemptive move is called a "hero play, ." I spent $12, and put the replacent in the AC cabinet .I await the chance to be a hero and take a bow.

You are OUTSTANDING!!! Thank You... world would be a much better place with folks like you!

[catblue]

Great and helpful video! I like it when a video shows how to use the multimeter in a specific job. 👍🏻

[ttom]

I'm an HVAC service tech and I would never put that much effort into a capacitor strap lol.

[nimrod]

Bad capacitor is such a common problem I think they design capacitors NOT to last more than a few years! HVAC companies make lot of money replacing a $20 part.

[james]

You said the lines were cold at the start when it was broken, but then at then end when you fixed it the lines are still cold?

[benjaminxu]

I did replace a new capacitor as all number are covered old one. But, the cold air not blowing. The fan runs perfect. What else problem could be possible? Thank you so much.

[katelatty]

Thank you sooo much!!! It was a Sunday and had same issue with fan working but no cool air. We bypassed getting the correct multimeter and went straight for the $23 capacitor from hardware store and just swapped it out, cheaper than getting AC repair person out on a Sunday and it did the trick, cool air!!! God bless you 🥵😅

[carlssiny]

Thank you, quick and easy fix. I ordered another one as a back up for half the price
