Hi all; I've been lurking in the shadows for a while and have come out with some good advice over the years. So, to start off... Thanks for all the past help! I've got a Lennox 10acc-036-230-02 compressor (condenser?) that just started not working yesterday evening. After shutting of power, waiting a while, then restoring power, it continues to not work. Neither the fan nor the compressor are running, but both are humming and get very hot (and the capacitor seems to be warm, as well). If I give the fan a push, it'll run, but not as fast as it used to. The fan bearings don't seem to be an issue, as it turns freely. I have no way to evaluate the state of the compressor (that I know of). From what I've picked up here (and other sites), my best guess is a bad starting capacitor. This unit uses a dual start 50 / 7.5 MFD 330 VAC, though Cozy Parts suggests that Lennox is now replacing them with a 50 / 7.5 MFD 440 VAC (which I've ordered). I should have no problem replacing the part once I get it -- it looks easily accessible. And yes, I understand the appropriate electrical safety concerns -- especially having been zapped a few times by capacitors I was sure could no longer hold a charge. :^o Now, the questions: 1) Am I on track here, or are there other things to consider? 2) Is there a way to evaluate the compressor? 3) Most importantly, after several hours trying to track down a capacitor locally (northern VA), I could find nobody to sell me a part. If they had parts, they only sold to contractors, or they wanted to send a tech out for a service charge of 80 to $300, plus $80 for a capacitor (which I bought for $20 from Cozy). Is it always this hard to find parts locally, or am I not calling the right folks? Where have y'all obtained parts in the past? Thanks, again!
