Philco Central Air Conditioner Condenser fan motor does not run
If your Philco central air conditioner's condenser fan is not running, the most likely cause is a failed run capacitor. A defective capacitor can make the condenser fan motor noisy, cause it to overheat, or keep it from starting. Next, check the motor control board, which can prevent the motor from running or maintaining the correct speed. If the board and capacitor are good, the condenser fan motor itself may have failed. The page also lists the condenser fan motor and capacitor as possible replacement parts, with the condenser fan motor being less common. This condenser fan troubleshooting requires care because the outdoor unit contains 240V line voltage, and a capacitor can retain a dangerous charge after power is disconnected. Turn off power at the disconnect box and circuit breaker before inspecting anything, and use a qualified HVAC technician for live-voltage testing or electrical repairs beyond your experience. Refrigerant work is not part of this diagnosis, but any sealed-system repair requires an EPA 608-certified technician. Enter your Philco model number to find the exact replacement run capacitor, motor control board, or condenser fan motor for your central air conditioner.
01 - Philco Central Air Conditioner Run Capacitor
If the run capacitor is defective, the fan motor might be noisy, overheat, or not run at all. To determine if the run capacitor has failed, inspect the capacitor. If the run capacitor is bulging or leaking, replace it.

02 - Philco Central Air Conditioner Motor Control Board
The motor control board helps to maintain the desired motor speed of the blower. When the motor control board fails, the blower motor may not run at the correct speed or it may not run at all.
To determine if the fan motor is working, use a multimeter to test the incoming voltage to the motor. If the fan motor is receiving the correct voltage but the motor still won’t run, inspect the capacitor to ensure that it is not at fault. If the capacitor is not bulging or leaking, replace the fan motor.
