The dual run cap on my central a/c condensing unit went bad (had a hole in the side of it, leaking). It was a 35/3 mfd 370v dual run. I ordered one on eBay http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=150483022031&ssPageName=STRK:MEWNX:IT, and I have installed it. The contacter is working, and if I flip the outside breaker on, the unit will cut on (fan and compressor) and will run for 5 seconds and cut off. I shut off the breaker, waited 5 min, and did it again, same result.
I then looked more closely at the cap and saw that it is actually a 470v. I didn't think that would matter, but would that be my problem? Or just a bad cap? Or did something else happen at the same time that the cap exploded. A/C was working fine, one day it wasn't, found the fan and comp not running, but very hot, found the bad cap. Thanks in advance for your help.
