I drew a schematic of the ADC and found the cause and fix for the "buzzing relay"
It's a bad electrolytic capacitor, C2, 22uF @50v
Try jumpering in a good one across it. (there is a protective coating over the entire board)
Watch the polarity and also be careful, the minus (-) side of the cap is connected to L1 120v HOT side of the power line.
I drew the schematic with MS Paint, and will soon draw it with a schematic program and upload it here. (a few messages below)
also, neither the compressor nor the defrost heater will work when the temp control is turned down (but the relay will still energize) try it at max cooling setting.
