Mitsubishi Electric Outdoor Fan Motor Failure

Outdoor fan does not run while compressor is operating, causing very hot air and possible shutdown

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Failed outdoor fan motor, Faulty fan capacitor (on non-inverter models), Faulty outdoor PCB fan driver, Obstructed fan blade

Safety first: Turn off power at the outdoor disconnect before inspection.

Steps:

Check for obstructions: Ensure nothing is blocking the fan blade and that it spins freely by hand.
Inspect wiring: Confirm the fan motor wiring is intact and firmly connected to the PCB or capacitor.
Capacitor check (if present): On models with a separate fan capacitor, a technician can test and replace a weak or failed capacitor.
Replace fan motor: If the motor does not run even with correct voltage and a good capacitor, replace the outdoor fan motor.
