How to Fix / Troubleshooting
Safety first: Unplug before internal checks.
- Step 1 – Reset control: Unplug for 10 minutes, then plug back in and try a simple cycle.
- Step 2 – Verify door/basket switch: Even if no error is shown, test the door/basket interlock switch for proper operation with a multimeter.
- Step 3 – Inspect connectors: Open the unit and check all connectors from the main control board to the heater and fan motor. Reseat them.
- Step 4 – Replace board: If switches and loads are good but the board never sends power to heater or fan, replace the main control board assembly.
