Condenser Fan Motor Burned Out / Faulty
Likely causes
Motor winding burned out (overheating, overvoltage)
Check: Measure winding resistance and insulation resistance
What to do: Measure winding resistance and insulation resistance → Prepare replacement of same spec (voltage, wattage, RPM, direction) → Check fan blade condition, then replace motor → Verify current and high-side pressure after replacement
Motor overloaded from bearing wear
Check: Prepare replacement of same spec (voltage, wattage, RPM, direction)
What to do: Prepare replacement of same spec (voltage, wattage, RPM, direction) → Check fan blade condition, then replace motor → Verify current and high-side pressure after replacement
Ground fault from insulation degradation
Check: Check fan blade condition, then replace motor
What to do: Check fan blade condition, then replace motor → Verify current and high-side pressure after replacement
Condenser fan motor is faulty. Replace with motor of same specification.
