Possible Causes
How to Fix / Troubleshooting
Safety: If you see smoke or smell strong burning plastic, stop the microwave immediately, unplug it, and keep the door closed to smother any internal flames. Do not continue using the appliance until the cause is identified.
Steps:
- 1. Allow to cool: Let the microwave cool completely before opening the door.
- 2. Inspect interior: Check for burnt food, splatters, or packaging that may have ignited. Clean the cavity thoroughly.
- 3. Check vents: Ensure vents are not blocked and clean any dust buildup.
- 4. Smell test: If the burning smell is electrical (sharp, plastic-like) rather than food, do not use the microwave again until inspected by a technician.
Internal component overheating (wiring, magnetron, transformer) must be diagnosed and repaired professionally.
