Whirlpool MH3184XPS over the range microwave coming on when using hood light

About a year after we got this over the range microwave it started "running" if the door wasn't quite shut all the way. It wasn't actually running, I guess, because it doesn't seem to heat up and the turn table doesn't turn; it just starts making noise like it's running (like a fan is on or something) and the interior light stayed on. If you tapped the door it would stop. By reading other solutions I'm guessing this has to do with the door latch. But now when you use the light over the stove, or the vent fan it does the same thing. Our solution has just been to leave the door open if we absolutely have to use either of these things, but it's annoying. What on earth could be wrong, and is it fixable?

This is usually caused by either a bad door switch, a loose door switch mount, or a problem on the control panel.

Even though a door switch clicks, it may still be bad inside.

This can be caused by slamming the door or by habitually opening the door while it's cooking without hitting the Stop pad first.

If you or a friend decide to look into it, we have critical information on safety, disassembly and door switches at our site, and our link is at our listing here on FixYa:

If you think the problem is on the control panel, which we repair these nationwide for $39.95 postpaid.

Hood light & exhaust fan not working

You have no power to the unit. Breaker is out or the hot wires into the hood has come apart. The wires coming into the unit usually terminated in a junction box next to the fan housing.
Teas it for power an/or reset breaker.

I have a whirlpool undercounter model # MH3184XPS-2 an has no power

On this model, this is usually a blown fuse or thermostat.

This model has three fuses, a 20A, a 4A, and a .25A and three cavity thermostats.

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.

mini_manual_behind_grille_small.jpgdee77f7.jpgAt our Web site, we have a video available showing how to remove a typical over the range control panel assembly in under 5 minutes.

Accessing the cavity thermostats 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.

If for some reason you don't still have yours, you can download Whirlpool owner's manuals and installation instructions here.

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

If none of the fuses or thermostats are blown, then the problem is probably on your control circuit board, which is especially common if you recently had trouble with your cooktop lights or exhaust fans.

We see (and repair) this a lot. The problem is on the control panel, which we regularly repair nationwide by mail for $39.95 postpaid with a one year guarantee.

The range-top light blew and now replacement bulbs

My Whirlpool/Roper microwave/hood combo has the same problem. I replaced the bulb twice, checked the bulb and it works, but not in the microwave. I wrote to Whirlpool asking about the problem. Haven't heard from them yet.

Whirlpool Microwave Hood Combination MH3184XPS-0 (October 2004), for no reason at all, this morning keeps beeping and running the power setting down from 10 to 1, and just keeps doing it in rapid sequence....

Ours just started doing this exact same thing this past Friday - 12/11/09. What's going on? The cook power just starts beeping all by itself and going from 10 down to 1 over and over again. It may stop momentarily, but then starts again within a minute or so - it's constant until we unplug it. We plug it back in and within a few minutes it starts doing it again. What gives?

Whirlpool microwavewave hood comination mh3184xp

My Whirlpool MH3184xps is shooting a spark when in use with the rack. When the rack is removed the oven works fine. I am guessing that some of the coating on the rack has cracked and peeled and is exposing some aluminum. Has anyone else had this problem?
