Our under the counter microwave suddenly stopped working today. Their is no power at all. Display, interior lights and microwave are all not working. I am hoping it's a fuse. Any help would be appreciated.

Thank you

Check your fuse in your house panel.

You can check this by plugging something like a light into the receptacle for the microwave.

If that is good there is a fuse in the microwave but it should be checked by a technician.

A microwave can be dead for many reasons.

If it goes dead for a while during or after cooking then comes back on, the magnetron is probably overheating and causing the magnetron thermostat to open. Then when it cools, it closes the circuit and allows power through again.

If it's intermittent or random, it may be a bad connection, usually on the control circuit board or a loose fuse holder.

If it went dead almost immediately after pressing the Start pad, that's usually a shorted high-voltage capacitor.

If it went dead a few seconds after pressing the Start pad, that's usually a failing high-voltage transformer.

If it goes dead or blows the breaker when you plug it in or open or close the door, then there's a problem with a door switch or door switch mount.

If the fuse is good, it may be an open thermostat or thermal cutout on or near the magnetron or on top of the cavity / body of the oven.
