Main signs of motor malfunction

The motor of the outdoor unit is crucial for refrigerant circulation and proper system operation. A faulty motor can lead to low performance or system failure.

1. Air conditioner doesn’t cool or heat

If your AC unit isn’t delivering cold or warm air as expected, a failed compressor motor could be the issue.

2. Unusual noises during operation

Grinding, rattling, or buzzing from the outdoor unit is a typical sign of motor wear or bearing damage.

3. Frequent on/off cycles

Short cycling may indicate overheating or electrical faults in the motor.

Common causes of motor issues

• Power surges or voltage fluctuations
• Dirt and debris clogging the fan or motor
• Damaged PCB control board
• Worn-out bearings or windings

How to avoid costly repairs

Regular seasonal maintenance and inspection of the control board and filters will help detect faults early. If you suspect an issue, call a certified HVAC technician.
