The magnetron has failed and has damaged the waveguide. This type of failure is generally unrepairable. First look in your owners manual for specific warranties, then contact Whirlpool and explain to them what has happened.

If you need further assistance, let me know

Sparking inside microwave door


There is exposed metal, when magnetron is running it will arc if there is exposed metal in the interior cavity which is more common, I have not seen this inside microwave door, inspect door carefully when you open it to see if there are bare spots. The manufacture use to sell microwave cavity paint to prevent this very problem, if this is not corrected it will short out the magnetron.

The problem is that the magnetron is arcing when it is running and it has found a couple bare spots 'exposing the metal'. The microwave uses a special industrial white enamel paint to prevent arcing, it is very important that the oven be removed from service until the situation is rectified otherwise there is a danger of shorting out the magnetron.

There is not any power in the door itself. However if the chassis has chipped paint or corrosion the RF from the microwaves magnetron will cause those bare metal areas to reflect the concentrated RF energy and cause sparking.

The only Whirlpool Microwaves that have been recalled, has a model number beginning with XC and had a green sticker on the bottom face area of the chassis where the door closed.

I have often been able to clean and paint the bare metal areas with the correct paint to stop the RF reflection sparks. Using the model number above it is white enamel "appliance paint" that you would use to paint the bare metal areas. A word to the wise.... do not sand outside the area to be painted. Otherwise you re-introduce your current problem post repair.

The model number you passed is missing the very last digit that would be from 0 to 7 (Eight models)

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.

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

Microwave sparks then will not work. Could it be the fuse? It is a Whirlpool.


It is tthe magnetron having the spark sometimes due to an insulation leak in the fitting .
Please check the spot where the magnetronis fitted to the cabin. Inside of the cabin there is a insulation cover and if some food particles are stuck on it due to non usage of food cover, then it is possible that the conduction of the food on this is smoking or causing an insulation break. So clean and remount the magnetron if not change the unit if the estimation is reasonable.

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 or so.

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.

Or if you prefer, you can order a new control circuit board for it here for $140.10 plus shipping. (Just enter the model number as MH1140XMQ-1 without the dash).

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