How to Fix / Troubleshooting
Safety First: Use caution with hot steam when opening the door.
- Use proper cookware and load: Ensure food is placed in microwave-safe containers and that sensor cooking instructions (covering, quantity) are followed.
- Clean cavity and sensor: Wipe down the interior and sensor area to remove buildup.
- Test with water: Place a microwave-safe cup of water in the center and run a sensor reheat cycle. If E3 recurs, the sensor or control may be faulty.
- Replace sensor: Replace the humidity sensor if repeated E3 errors occur. If the problem persists, the main control board may need replacement.
