How to Fix / Troubleshooting
Safety first: Unplug and cool the unit before working near the heater or fan.
- Step 1 – Confirm symptom: Start a cycle and listen. If you do not hear the usual fan noise but the heater glows, shut off and unplug.
- Step 2 – Inspect fan blade: Look inside the cavity at the fan. Check for broken blades or obstructions. Remove any debris.
- Step 3 – Access motor: Remove the rear or top panel to reach the convection fan motor. Check that the blade is firmly attached to the shaft.
- Step 4 – Spin test and continuity: Spin the fan by hand; if stiff, the motor is failing. Test motor windings with a multimeter; replace the motor if open or shorted.
- Step 5 – Control board: If the motor is good but never receives voltage, replace the main control board.
