How to Fix / Troubleshooting
Safety first: Unplug the microwave before accessing the control board.
Step-by-step checks:
- 1. Verify actual outages: Confirm that your home power is not flickering or dropping.
- 2. Surge protection: Use a quality surge protector to reduce power spikes.
- 3. Control board replacement: If the microwave loses settings even after short, normal unplugging, the control board's memory or backup circuit is failing and the board should be replaced.
