Question about Whirlpool MH1150XM Convection/Microwave Oven

1 Answer

Whirlpool microwave model mh1150xmb

The light bulb on the underside that would light up the range cook top burned out. I replaced the bulb as I have done dozens of times and it still does not turn on. I tested the bulb to verify that it was good and it was so, I then inspected the lamp holder and it appears to be in good shape. The button (switch)on the control panel that operates the light does make a beep when you press it (it always has) to turn on the light; is there a way to test this switch without dismantling the micro-wave? Or is there a known condition of the switch since it does make a tone when pressed?

Please test this steps and fix it. God bless you

  1. Light bulbIf your microwave light bulb is not working, perhaps it has blown. The first step is to replace the bulb and power on the microwave. If this does not correct the issue, the next step is to check the socket and wiring to verify if that is the problem.
  2. Light bulb socket & main control boardIf your microwave light bulb is not working after the installation of a new bulb, check the light socket as well as the wiring to ensure they are properly operating. If these sources are functioning properly, the next step is to check for a faulty control board as a possible root cause to your microwave light bulb malfunction.

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 in about a week.

At our Web site, you can get details of our service, plus we have a video available showing how to remove a typical over the range control panel assembly in under 5 minutes.

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.

The lights fan can be inoperable or stuck on or no bright, too. Sometimes this will similarly affect the exhaust fan operation, too.

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.

The range top bulbs can be replaced by removing the screw that holds the glass and frame to the underside of the unit, they swing down, the bulbs usually screw in, the power needs to be turned off by way of unplugging the unit before replacing the bulbs, the interior cavity bulb can be replaced by removing the top grille and accessing the socket assy from the front.

It's important that high-current devices like microwaves be on their own dedicated breaker.

I would suspect the 20A fuse and then the oven cavity thermostats, in that order.

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

Accessing some components (such as the oven cavity thermostat) 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.

You can download Whirlpool owner's manuals and installation instructions here.

Model #mh1150xmb-0 The light bulb under the microwave burnt out (with a bang) this morning. Although the lights and clock come on the microwave it won't start.


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.

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, cooling fan, turntable, and/or inside light operation, too, and on these models, can prevent them from starting or running.

Details of our service are at our Web site, along with a video showing how to remove a typical over the range control panel assembly in under 5 minutes.

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.

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

I recommend that you bookmark that link to your favorites. Hope this covers it.

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.
