I have a Maytag microwave Model No. MMV4205AAQ. The exhaust fan is just kicking on for no reason. I unplug the microwave and when I plug it back in the fan starts up within a minute or two. I used it to heat something and the fan has not automatically turned back on. Do I have a short? I don't want to have a fire hazard.

SOURCE: Door handle broke on my

Hi ,

There is a inner door trim on the inside of the microwave door that can come off to expose the screws for the handle. This trim is held in place by clips built into the trim, ( some older models may also have screws - look for them and remove before going any further ) the tabs on this trim can break easily but with a putty knife and some patience, the trim can be removed to get at the handle screws. See picture help. This trim can be pushed so the clips will "pop" back into place after the handle repair.

It may be the line fuse, the oven thermostat, or the magnetron thermostat.

There should be a "mini-manual" hidden inside the unit behind the control panel or hidden on the left side behind the grille, which is very helpful when troubleshooting, & testing.

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

Accessing some components for testing and possible replacement will require you to remove the oven from the wall.

If so, the installation instructions are very handy, and it's best to have two people since the microwave can be heavy and awkward.

Kenmore elite microwave

Was it just the exhaust fan that came on? If so this is normal when cooking on the stove for long period of time without the fan running. The heat builds up under the microwave and eventually activates the fan.

I would say the oven thermostat has shorted or you may have a stuck relay on the control panel.

The first thing to try is a "hard reset". Unplug it from the power line for a few minutes, plug it back in, set the clock, then try again.

Let us know if the hard reset doesn't fix it.

Maytag mmv1153aaw ehaust fan turns on

Normally the hood / exhaust fan comes on when you turn it on, or when the temperature at the bottom of the microwave gets high enough to close the hood thermostat.

Sometimes a failure of the hood thermostat or on the control board can cause intermittent or unintended operation of the hood fan.

A thermostat can only trip so many time before it fails permanently.

One way to test it is to unplug one wire from the thermostat, tape it up to prevent it from shorting, and see how it acts for a couple of days.

If it stops failing, the hood thermostat is bad., If it continues to fail, chances are you have a failure on the control board, which we can repair for $39.95 in most cases.

My microwave continues to run, (turntable and exhaust), when the door is opened.

all microwaves have 2 safety switches at least... but these are tied to a set of relays that turn it on, my bet is a sticking or stuck relay because you unplug it right and plug back in its not running?-relay ... if always runs driver transitors.
