Question about Whirlpool MH1150XMQ Microwave Oven

Microwave external underside light no longer works

Whirlpool Microwave Oven Model # MH1150XMQ, old bulb replaced with new bulb, Microwave operated/heats fine, turntable, clock, timers etc all work fine and internal oven light works fine, everything works except underside counter top light. When touch panel on/off light switch is pushed common operations sounds report as tho switch is signaling but bulb socket is not getting power. FYI...bulb replaced was fogged/smoky gray internally, not sure is this is standard appearance for a 30W burned out bulb but perhaps this may help identify/diagnose a problem. Will appreciate any ideas or help with this problem.

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.

We have had this microwave for 7 years. Not had any problems until about six months ago when the volume went way down when you push the buttons and timer, but still heated. Then all of a suddon it does...


Remove the cabinet ... check the door safety interlock switches for proper operation. Most of the time, no heat problems can be traced to the oven thinking the door is open. These switches tell the oven if it is open or closed. If they are faulty ... well ... the oven thinks the door is open and will not turn on the heat.

Make sense?

Thanks for your question today.

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.

either the h.v. diode,h.v. capacitor or the magnetron tube are suspect here due to the no heat condition you have

Does not heat food


It could be 3 problems. 1. the part that spits out the microwaves needs replacement, door hinge switch is broken, or circuit board need replacement. First check with Whirlpool and see if it is under warranty still. Call a repair man. See www.repairclinic.com .

About 95% of the time it is the magnatron. If the microwave is under 5 years old that part is often covered under warranty. I would check your manual. If not the p/n is 8206335 and it's about $80 and fairly easy to install. I just looked and the magnatron is covered.

Labor to replace it would be about $125

Does the turntable rotate? If everything but this works (except no heat), you probably have a bad door switch. Here's a discussion of what's involved in replacing it: http://www.fixya.com/support/t267796-kenmore_microwave_hood_combination_over

If the turntable does rotate, I'd suspect a more significant failure, such as the transformer, capacitor, or magnetron. If it's any of these, it's time to replace the unit.
