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.

We have *critical* safety, disassembly, and troubleshooting info at our site, and our link is at our listing here on FixYa: http://tinyurl.com/yzjozk

You can also find helpful exploded view diagrams and order parts by entering your full model number here: http://tinyurl.com/gv383

There should also be a very helpful "mini-manual" hidden inside the unit behind the control panel. It's very helpful when troubleshooting.

Maytag Model MMV1153AAW vent won't turn off; we have to unplug it and plug it in to use it so the vent won't run 24/7. When we plug it back in to use it, the vent comes on within 15 seconds and might shut...


Hi,
Either your thermostat or relay to the blower has faulted. Thermostat is cheap but the relay is on the control board. So either replace the thermostat P#53001373 or replace the microwave as the control board is discontinued according to the information you provided. Good Luck

Unfortunately, if you have cut a wire internally then any warranty will be void.

Have you investigated why the transformer is sparking? This sounds like either a serious problem with the transformer or simply a loose connection.

I assume when you cut the wire you have made sure that it is insulated from the chassis?

Exhaust fan runs continuously on Maytag microwave. Please help

You probably have either a shorted base thermostat on the base of the chassis of the oven or a shorted fan relay on the control circuit board.

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.

d:%5cele%5crepair%5cmicrowave%5cge_hotpoint%5cmini_manual_behind_grille_small.jpgdee77f7.jpg

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 find helpful exploded view diagrams and order parts by entering your full model number from the tag on the oven here.

We have the service / repair manual for this model and have uploaded it to our site here for free download to help you.

The base thermostat (which I believe has thinner pink and yellow wires attached, but not thicker black wires) should read normally open. If it shows continuity (virtually zero ohms or shorted) then it is bad.

Otherwise, I would say you have a shorted fan relay on the control circuit board.

We regularly repair such control units for customers nationwide by mail for $39.95 postpaid in about a week or so with a one-year guarantee.

Feel free to contact me directly (and please remind me of your full model number from the tag on the unit) for more information & help.

We're happy to help you with free advice and we'd appreciate your thoughtful rating of our answer.

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.

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

It may be an open fuse, magnetron TCO or oven cavity TCO.

Accessing the oven cavity 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.

I have the same problem with mine!!! I spent 58 dollars to have a 6 dollar diode replaced. Now 8 months later... same prob. Replaced again myself and working fine again. Just make sure you label the wires while working on it. I didn't and it cost me 2 new fuses! Hope this helps.
