Possible Causes
Blown internal line fuse, faulty power cord, failed mains filter, open thermal cut-out on cavity or magnetron
How to Fix / Troubleshooting
Safety: Unplug the microwave before any inspection. Internal components may still hold charge.
User-level checks:
- 1. Check outlet: Test the wall outlet with another appliance to confirm power is present.
- 2. Inspect plug and cord: Look for visible damage. If the cord is damaged, do not use the microwave.
- 3. Reset breaker: If the circuit breaker has tripped, reset it once. If it trips again when the microwave is used, stop and seek service.
Technician-level checks:
- 4. Inspect internal fuse: Replace the line fuse only after identifying and correcting the underlying fault.
- 5. Test thermal cut-outs: Check continuity of cavity and magnetron thermal cut-outs and replace if open.
Because internal access involves mains and high voltage, most users should contact a Sage-authorized technician for a dead unit.
