How to Fix / Troubleshooting
Safety: Unplug the microwave before accessing internal components.
- Check model-specific parts: Verify that any recently replaced control panel or keypad matches the exact Whirlpool model and part number.
- Inspect UI harness: Remove the control panel and check the harness between the user interface (UI) board and main control board. Reseat connectors.
