    Maytag MMV5156AAS 1000 Watts Microwave Oven-

    I have this model. Just before the Magnetron blows (I have replaced 4 of them now in the 5 years I have owned it-and the entire unit has to come out of the wall bracket and opened up by a trained technician-I did it myself 3 times, but it has to be unplugged and totally discharged carefully.) It will not heat all the way, or not at all intermittently. It will really smell terribly when it does blow. This last incident (2 days ago) the fins inside the magnetron totally twisted up. I am not sure if this unit is now worth fixing further . Magnetrons cost about $100.00 each time. If this unit continues to do this, it seems cost effective to get a new microwave entirely. The GE brand over the range type, seems to get good reviews on Consumer Reports. -Christine H.

Generally, the most common causes of a failure to heat are:

- bad door switches or door switch mounts
- loose connection at the magnetron
- problem or loose connection on the control unit circuit board
- bad magnetron or other high voltage part (such as a shorted diode)

Make sure your microwave is fully cleaned out of any old dried food residue and that you are not using any kind of metal items in your microwave when you cook because this will certainly cause smoking and sparking inside your microwave.

Most like you had some corrosion or food particles stuck to your WAVEGUIDE COVER PLATE.

Here is a link to a short video that show you exactly how to replace the wave guide cover yourself:

We were using the microwave the other night and it started making a loud noise like the fan was running (although the fan was not). We let it sit for awhile and try to use it again but the noise came...

The loud noise and no heat means that the magnetron has failed. It the part that generates the microwaves that heat the food. When it fails it shorts out, causing the transformer to heat up. That is what was causing the burning smell. The cost of a replacement magnetron is around $130-150 range so it may not make sense to have it fixed.

Cooked food smells funny,could it be a leak?

Unless you can associate the odor with burning electronics, it probably isn't being caused by the microwave.

When I start the microwave, it has a funny smell

Sounds like you burned out the magnetron, if so you should discontinue use immediately. This is the bit that emits the microwaves and they will fail with a burnt faintly oily smell to an acrid chemical smell. Magneton replacement should not be attempted by the amateur fix-it man, Find a reputable appliance repair shop or chuck it in!

Hi,It is most likely the magnetron and diode that has to be replaced. This job should be done by a tech, High voltage. Magnetron's normally have a five year warranty, check your owners manual.
