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.
