Possible Causes

How to Fix / Troubleshooting
Safety: Unplug the microwave before any disassembly.
Steps:
- 1. Observe symptoms: Note if the fan, light, or turntable runs when it should be off. This helps identify which relay may be stuck.
- 2. Inspect control board: Remove the control panel and examine the board for burned or discolored areas near relays.
- 3. Replace control board: In most cases, individual relay replacement is not practical for consumers. Replace the entire control board with the correct Avanti part.
- 4. Check for moisture sources: Ensure that steam from cooking is not directly venting into the control area; verify that gaskets and covers are in place.
