Possible Causes
Failed evaporator/circulation fan motor, Fan blade obstructed by ice or wiring, Loose fan connector, Control board not sending power to fan
How to Fix / Troubleshooting
Safety: Unplug the cooler before removing interior panels.
Steps:
- Access fan: Remove the interior rear panel to expose the evaporator/circulation fan.
- Check for obstructions: Clear any ice, wiring, or insulation blocking the fan. Ensure the blade spins freely.
- Test fan motor: With a multimeter, check for voltage at the fan connector when the compressor is running. If voltage is present but the fan does not run, replace the fan motor.
- Control board: If no voltage is present and wiring is intact, the main control board may be faulty.
