Possible Causes
Shorted high-voltage capacitor or diode, Shorted magnetron, Shorted line filter or wiring, Overloaded circuit shared with other appliances
How to Fix / Troubleshooting
Safety first: Do not repeatedly reset a tripping breaker; this can be a fire hazard. Unplug the microwave.
External checks:
- Ensure the microwave is on a dedicated circuit as recommended by Maytag.
- Remove other high-draw appliances from the same circuit.
If tripping continues with only the microwave on the circuit:
- Internal components are likely shorted (e.g., magnetron, capacitor, diode, or line filter).
- These are high-voltage parts; have a qualified technician diagnose and replace the defective component.
