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.

This light failure often occurs when a bulb goes out and the filament shorts, or when the bulbs are removed or installed without first unplugging the oven from the power line. Either can cause such a failure on the controller.

This can often also affect the exhaust fan operation, too. The lights and fan can be inoperable or stuck on too.

Details of our service and critical safety information and disassembly information is at our site, and our link is at our listing here on FixYa.

Feel free to contact me directly for more information & help.

I've got grease dripping down from the top left inside corner of my otr microwave. I've cleaned the grease filters. Is it a problem with the vent to the outside?


Without a long explanation as to why but they will get a build up. At this juncture i would be prudent to just clean it well. Because it will require you to remove the outer cover, you must disconnect it. Be careful when you do this, no metal objects. It has parts that store electric. Once you open it you will see the build-up. Do not open the metal box, it is the part that stores the electric.

Hello, Thank You for using FixYa. I will be helping you today.Make sure no wires were pinched in the process. The turntable motor runs off the board that's why im thinking you have a grounded wire somewhere.
Thank You and please rate my answer if it was helpful..

How to set it to high, med or low


Grease filters can be cleaned, according to your manual.

If you've misplaced yours, it's online here.

Charcoal filters cannot be cleaned and must be repaired.

From the manual:

Reusable Grease Filters
The reusable grease filters should be cleaned at
least once a month. Never operate the
microwave without the filters in place. In
situations where flaming might occur on
surfaces below the hood, filters will stop the
entry of flames into the unit.

To Remove Grease Filter
To remove grease filter, grasp the “finger hold”
on the filter and slide to the rear. Then pull filter
downward and to the front. The filter will drop
out.

To clean Grease Filter
To clean grease filters, soak and then agitate
filter in solution of hot water and detergent. Do
not use ammonia or ammonia products because
they will darken the metal. Light brushing can
be used to remove embedded dirt. Rinse, shake
and remove moisture before replacing.

To Replace Grease Filter
To replace grease filter, slide the filter in the
frame slot on the back of the opening. Pull filter
upward and to the front to lock into place.

Light won't go on; Model MMV1153WB-O


You can download owner's manuals and installation instructions for several brands (including Amana, Frigidaire, Jenn-Air, Kitchenaid, Litton, Maytag, Roper, Tappan, Thermador and Whirlpool) here.

Enter it as MMV1153WB0 (no dash, zero on the end, not "oh")

Or just get it here, to be more exact.
On page 4, it says:

"Installing/Replacing Filters and Light Bulbs
■ Grease filter: Grease filter is on the underside of microwave
oven. Clean monthly. Slide the filter away from the tab area,
and drop out the filter. To reinstall, place end of the filter into
the opening opposite the tab area, swing up the other end,
and slide it toward the tab area.
■ Charcoal filter: The charcoal filter is behind the vent grille at the
top front of the microwave oven. The charcoal filter cannot be
cleaned, and should be replaced about every 6 months.
Remove 2 screws on the vent grille, tilt the grille forward, lift it
out, and remove filter. To reinstall, place the filter into its slotted
area – wire mesh side up, replace vent grille, and secure with
screws.
■ Cooktop light(s): The cooktop light bulb(s) is(are) located on
the underside of the microwave oven, and is(are) replaceable.
Remove bulb cover screw, and open the bulb cover. Replace
bulb, close bulb cover, and secure with screw.
■ Cavity light: The cavity light bulb is located behind the vent
grille at the top front of the microwave oven, under the bulb
cover, and is replaceable. Remove 2 screws on the vent grille,
tilt the grille forward, and lift it out. Open bulb cover and
replace bulb. Close bulb cover, replace vent grille, and secure
with screws."

HINT: Unplug the oven before removing or installing the bulbs, or you may need this service.

Why double filter on Maytag Microwave


If your range hood or microwave recirculates back in to the room.

Both filters are required. The mesh filter catches the grease & air particulate. The carbon filter should be changed regularly www.HoodFilterFactory.com ( avoid range fires that spread quickly) & clears the recirculated air from smoke,odors, & airborne particulate.

With yours venting to the outside, you ONLY need the mesh filter. These filters should be cleaned regularly ( Avoid mentioned hazard) & should be replaced when you can no longer clean them enough to see through them when holding up to the light.

Good Luck

I cleaned the vents on my over the stove micro wave (whirlpool), it was full of grease. I sprayed fantastic and the then cleaned. All was fine, but somehow now only the fan and light come on when I close...


The controls have gotten wet. If they don't dry out over time, you'll need a new keypad and/or control board.

I always recommend that users instead spray cleaner on a soft cloth then wipe the control panel.

And the grille can be removed and cleaned separately.

Also be sure to clean your grease filters regularly. The owner's manual will probably tell you to remove them and clean them in a sink with warm soapy water.

If you're using a charcoal filter, it must be replaced (not cleaned) every six months or so.

You can find links to helpful exploded view diagrams and part ordering help here.

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.

I was given a Whirlpool microwave. I think it's 6


Not really over the short term, if the vent discharges back into the room. If it is of the type that discharges through the ceiling, you could have grease build up in the vent over time. I found replacement generic filters the other day at Lowe's. But, I wasn't looking for filters at the time. Check there or a similar store.

Good luck,

Microwave message says to replace charcoal filter. User manual states charcoal filter is used if unit is not vented outside. Our unit is vented outside


External vent systems have the charcoal filter removed, generally at the time of installation, as it is not needed for this application.
The charcoal filter removes odors from internal recycled airflow.
There should be an aluminum grease filter that you can remove to clean in a warm soapy solution, let dry, and reinstall.

Clean vent


The vent (also known as grill assembly in GE literature) comes off after removing the two screws at the top of the unit and gently sliding the entire assembly to the left about an inch. This will allow the vent to be cleaned of grease, hair, etc., as well as giving some access to the areas behind the vent.
