Possible Causes
Blown internal line fuse, faulty mains power cord, tripped thermal fuse on cavity or transformer, failed control PCB power supply
How to Fix / Troubleshooting
Safety: Unplug the microwave before opening the cabinet. Internal components can still hold charge.
User-level checks:
- 1. Outlet test: Plug another appliance into the same outlet to confirm power is present.
- 2. Cord inspection: Check the Tower microwave's power cord for cuts, burns, or kinks. Do not use if damaged.
- 3. Reset breaker: Check your consumer unit / breaker panel and reset any tripped breakers.
Advanced:
- Remove the outer cover and locate the main line fuse near the power cord entry.
- Test the fuse with a multimeter and replace only with the exact same rating if blown.
- Check any thermal fuses on the cavity or transformer for continuity.
- If fuses blow again immediately, there is a deeper fault (e.g., shorted transformer) that must be diagnosed.
Warning: Repeated fuse failures indicate a serious internal problem. Do not bypass fuses.
