A ten year old 6000 btu Amana Quiet Cool window A/c in the shop quit running after I had smelled hot electronics for a short while. The circuit boards, the fan motor, and the wiring don't look smoked; but the condenser is so rusty I wonder if it might be the cause of the smell. The circuit diagram is illegible from exposure to rain, etc. The fan motor has three leads so I suspected it is a typical three speed motor setup and it was confirmed on the label but the label gave no color codes for the wires. The compressor also has three leads and a (common?) lead comes in through a separate thermal switch .
The part I find confusing is a big capacitor which has three leads and a rating of both 7.5 mfd and 35 mfd. From looking at the label on the blower motor, it doesn't appear to be a capacitor start or capacitor run motor, so I would guess that both the blower motor and the compressor use the capacitor simply to give them a little more amperage when they start up since they both start at once on some settings of the dial; but that's just a wild guess. If the fan motor and compressor are both good, I would like to hook them up to a household type 24v transformer, relay, thermostat arrangement and eliminate the pc boards whether they are good or not. I'm a little afraid to try 110v on the fan and compressor to see if they are good since I'm not familiar with pc board controlled appliances and they may require some sort of hookups with the capacitor. Both the fan motor and the compressor are thermally protected so it probably would be safe enough. All suggestions will be appreciated.
