How long can a microwave oven run continuously?

It is usually the inside which is poorly maintained by the user, with accumulated spattered food, and accumulated moisture causing a rusting out of the metal on the door or walls, or the vent leading outside the oven. The electronics controller should be good for 1000 to 5000 hours.

Is it bad to run the microwave too long?

Typically you can even run a microwave for 2-3 minutes, sometimes longer while empty (no load) and it will be fine. This is what happens when you run it without a load. At first, everything is fine because the cavity, the door, the tray (or shelf) absorb the excess energy.

Can a microwave be on for 20 minutes?

Is a 25 year old microwave safe?
