Hello Well now it is about time to get the bloody unit working! I cleaned the Condeser Coils with the foam cleaner and hosed it off. Also replaced starting capacitor and 30 amp panel breaker in main breaker panel inside house. See detail and pics in link below. http://www.hearth.com/talk/threads/...r-buzzing-after-the-coil-cleaning-help.88931/ I cleaned the Evaporator A Coil with the Evaporator cleaner that does not need rinsing Also vacuumed the return air filter and vacuumed out the Evaporator and fan housing. See detail and pics in link below. http://www.hearth.com/talk/threads/...coil-cleaning-and-orientation-question.88982/ I also patched up duct leaks in the attic with foil tape! The next step if to get a new Contactor! So here are my 3 questions to you AC experts? ? ? 1. Will a new contactor solve the problem of the 30 Amp breaker tripping? If not is it a compressor going bad? 2. Will 5 more amps of contactor relay load capacity help? 3. Since the old contactor is a single pole does that mean there is a heater in the compressor that is powered on when the compressor is not running to warm the R22? The old one was single pole with 24 VAC coil 3100-150179 Voltage___FLA__LRA 240/277___25___150 ______________________________________________________________________________ The new one I got is 2 pole 24 VAC coil and is better because it is more enclosed. I only need one pole so If I hook up 1 pole and it wears out then I can use the other pole. It will last twice as long! They did not have a 25 FLA so I got the 30 FLA with specs shown below: Voltage___FLA___LRA 240/277___30____160 Pic 1 shows old contactor exposed coil - see yellow arrow Pic 2 shows old contactor shunt - see yellow arrow Pic 3 shows wires connected to the new contactor the same as the old contactor However to use this double pole as a single pole the 2 black wires at the top were removed and pushed onto the bottom clips next to the black incoming hot lead. See Green Arrows in pic. So I did change the black leads to the bottom terminals, then started up and AC is still running. It has only been about 3-4 hours so far!
