It sounds like the thermal fuse may be defective, or the fan is not running, or the magnetron is getting to hot. If there are any heat issues the thermal fuse will cut power and reset in 5 minutes.

it is an internal fan that is the problems, if this is a counter top MW just replace it. if Over The Range (OTR) and under warranty call for service. if out of warranty replace.

I would bet that either your internal cooling fan is not running, or the magnetron is otherwise overheating.

We have a sound clip of what a microwave should sound like when the cooling fan and high voltage section are operating here.

It is vital that the cooling fan runs, or the magnetron will be destroyed.

The magnetron is overheating, tripping the thermostat, which shuts off all power until it cools down.

This is usually caused by a blocked air vent, failed internal cooling fan, or failing magnetron.

If it's out of warranty, I'm sure you'll find it's uneconomical to repair, even if you could get parts for this brand.

Good luck.

I have a Samsung model 1032BB in my R.V. Starts up all by itself and then I can't turn it off/on; have to unplug it. Should I have it repaired or should I replace it?
