The compressor and fan runs to dry out the air blowing onto the windshield. It's free turning when I turn it with a screwdriver (not bound). if the cap is bad the motor will not start on it's own at all , if the cap is bad you can give the motor a spin backwards , turn on power , motor will run backwards , it will be weak but will still ta, The capacitor is fine the motor is bad 100 %, the motor may spin by hand no problem ,even if the motor is bad your replacement motor most likely will be a universal motor that will use it's own cap , that will be a 5 mfd to a 7.5 mfd . Compressor still running. Sometimes it will stay on longer than other times. Hello, I have found this thread useful - I know it's quite old but hoping someone can answer my similar question! Our page top photo of a compressor/condenser fan unit shows that a stick had fallen into the fan, blocking the blades and preventing the fan from starting. Changed compressor starter capacitor but not the dual run capacitor. I had a HVAC Repair company come out over 5 times trying to fix it. Welcome to the forums. Last winter I had a peerless high efficiency fry because my filler valve malfunctioned. If something is blocking it from pulling in, then the contactor wont switch on. You have a bad condensor fan. Heres What to Do. There is more than one possible cause of a noisy air conditioner. Over time, the contactor switch gets worn, and will stop providing voltage to the condenser fan. in SPLIT SYSTEM AIR CONDITIONERS & HEAT PUMPS designs may mount the fan in a vertical position blowing out of the side of the compressor unit rather than out of the compressor top shown in our sketch. The compressor is depending on the fan to move air across the condensing coil to convert high pressure, high temperature gas back to a liquid refrigerant. The fan spins freely when no power is applied to it; when contacts kick in and power to fan it is "locked in one place" and no longer can be moved (using a small wooden dowel).
