How to Fix / Troubleshooting
Safety first: Unplug the microwave before any inspection. Internal components can be hazardous.
- Check outlet: Plug another appliance (like a lamp) into the same outlet to confirm it has power. Reset any tripped breakers or GFCI outlets.
- Inspect power cord: Check the Danby microwave's power cord for cuts, burns, or kinks. Do not use the unit if the cord is damaged.
- Internal fuse (advanced): If you are experienced, remove the outer cabinet (with power disconnected) and locate the internal line fuse near where the power cord enters. If the fuse is visibly blown, it must be replaced with the exact same type and rating. A blown fuse often indicates another fault (door switch, HV component) that must be diagnosed.
- Next step: If the new fuse blows immediately or you are not comfortable opening the unit, contact a professional technician. Do not bypass or upsize the fuse.
