How to Fix / Troubleshooting

Safety: Unplug the unit before removing interior panels or touching the fan.

Steps:

  • Access fan: Remove the interior rear panel to reach the evaporator fan.
  • Clear obstructions: Remove any ice, labels, or wiring that may be contacting the fan blade.
  • Test motor: Spin the blade by hand; if stiff or noisy, the motor is likely failing. Measure resistance across the motor; an open circuit indicates a bad motor.
  • Replace fan assembly: Install a new evaporator fan motor and blade if necessary, ensuring correct wiring and rotation direction.
