Comfortmaker Central Air Conditioner Condenser fan motor does not run
If your Comfortmaker central air conditioner's condenser fan motor does not run, the outdoor condenser fan may not be spinning, which can cause the system to overheat and stop cooling. The most likely cause is a failed run capacitor, especially if it is bulging or leaking. Next, a defective motor control board can prevent the motor from running or maintaining the correct speed. A failed condenser fan motor or capacitor is also common. With power disconnected, you can inspect the capacitor for visible damage and check for loose wiring, but capacitors can retain a dangerous charge. Testing incoming voltage with a multimeter and replacing components inside the outdoor condensing unit involves 240V line voltage and should be handled by a qualified HVAC technician if you are not trained to do so. This repair normally does not require refrigerant handling, but any work on the sealed system does require an EPA 608-certified technician. Enter your Comfortmaker central air conditioner model number to find the exact run capacitor, motor control board, fan motor, or condenser fan motor for your unit.
