This is a problem in one of the damper-related components, most likely the switch, but it may also be the motor or the damper door.

The damper closes and opens depending on cooking mode. See the attached sample photo.

The damper is a door located on the right side of the innards. The damper closes and opens depending on cooking mode. See the attached sample photo.

I have a Kenmore microwave. The vent will just start on its own and can't shut off


Actually, that's a feature! If you cook much on the range (stove) beneath the microwave, the heat will cause the microwave bottom to heat up quite a bit (just touch it!), and the microwave will turn on it's exhaust fan in an attempt to save itself from burning up. It will shut off in about 15 minutes after you turn off the source of heat.
But if the fan comes on by itself even when the microwave is cool (or at least not hot), then you probably have a defective fan thermostat. This thermostat is located behind the control console on the inside bottom of the microwave.

If you try to heat something for a minute , the microwave will turn on for about 15 seconds then shut off . It doesn't even seem to warm the food.


It may need a reset. You can do that by unplugging the power for a minute or two, then plugging it back in and setting the clock.

If it still fails, you may have a failing cooling fan or a problem on the control circuit board.

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.

Why don't you return it? I think this is a common problem. We returned ours to Home Depot with no questions asked.

My microwave heats but shuts off due to the fan not coming on


A little late for a reply; you probably have replaced it by now.

I suspect it shuts down because the fan is no longer turning on and there is probably a thermal shutoff switch near or on the magnetron to prevent the chance of fire.

Microwave problem


Could be that magnetron is not receiving adequate cooling thus causing thermal protector to open. This is mounted on the magnetron.
