Possible Causes
How to Fix / Troubleshooting
Safety: Unplug the microwave and allow it to cool completely.
Steps:
- 1. Ventilation: Confirm that all vents are clear and that the microwave has the recommended clearance from walls and cabinets.
- 2. Clean filters (OTR models): Remove and clean grease filters; replace charcoal filters if clogged.
- 3. Cool-down reset: Leave the door open for 30–60 minutes, then plug back in and test.
If E15 returns quickly, the magnetron thermostat may be defective or the cooling fan may not be moving enough air. These components are internal and should be tested and replaced by a professional.
