Question about Microwave Ovens

1 Answer

Microwave will not shut off Amana MVH230W/01 fan will not shut off.  While I was cooking on the range under this unit, the fan came on by itself and I can't shut it off.  Tried unplugging it several times for 5-10 mins and as soon as I plug it in, the fan starts with no way to stop it.

Your hood fan thermostat is probably stuck "on" and will have to be replaced.

There should be a "mini-manual" (tech sheet) hidden inside the unit behind the control panel or hidden on the left side behind the grille, which is very helpful when troubleshooting, testing, and locating components.

At our Web site, we have a video available showing how to remove a typical over the range control panel assembly in under 5 minutes.

You can usually find helpful exploded view diagrams and order parts by entering your full model number here.

Cannot turn microwave off. Help


Only happens when cooking a big pot under the microwave? Hosing thermal fuse / thermostat kicks in to cool the microwave. Is the micro. Installed proper height above the range? Are you using the fan when cooking on the range?

Have Kenmore microvave and the vent starts on its own


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.

My fan kicked on by itself and won't shut off


Hi,

The over the range microwave hood has a heat sensor in it. If it senses hot temperatures from cooking below it will turn the fan on. The fan will turn off once it cools down, this is to protect the microwave controls from damage.

Amana Microwave stays on when I shut the door.


It'll be a bad door switch or a loose door switch mount.

There should be a "mini-manual" (tech sheet) hidden inside the unit behind the control panel or hidden on the left side behind the grille, which is very helpful when troubleshooting, testing, and locating components.

Shuts itself off mid cooking cycle -- as if unplugged; then after 5 minutes or so turns itself back on as if it was just plugged in (forgetting all previous settings)


If you just put the fan blade back on, it will almost certainly fall off again.

The best bet is to slightly rough up the contact area of the shaft with sandpaper and use a little super glue to hold the blade assembly on the shaft, and let it set a few minutes before using it.

I always recommend that you use the hood vent exhaust fan when cooking on the stove top to keep heat, steam, and grease out of the controls.

Microwave stopped working completely


Fan turned on after cooking because a thermostat got to hot and tripped turning on the fan to try to cool the unit.  The unit went completely dead when thermal fuse tripped which is located above the cavity on the left side.
