Mammoth Central Air Conditioner Condenser fan motor does not run
When your Mammoth central air conditioner has a condenser fan not running, the most likely cause is a failed run capacitor. With power disconnected, inspect the capacitor for bulging or leaking, since a bad capacitor can make the condenser fan motor noisy, overheat, or stop completely. Next, the motor control board may be preventing the motor from running or reaching the correct speed. If the board is working, the fan motor itself may have failed, followed by the condenser motor or a separate capacitor, with the condenser fan motor being a less common cause. A seized motor or damaged condenser fan blade can also stop operation, so inspect the blade for obstruction and confirm it turns freely. This condenser fan motor troubleshooting involves electrical testing: checking incoming voltage requires access to 240V line voltage, so have a qualified HVAC technician handle live voltage tests and any wiring or control-board repair. Refrigerant work is not needed for these parts, but any sealed-system service requires an EPA 608-certified technician. Enter your Mammoth model number to find the exact run capacitor, motor control board, capacitor, or condenser fan motor for your central air conditioner.

02 - Mammoth 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.
Common
03 - Mammoth Central Air Conditioner Fan Motor
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.
