My 5 year old (over the range) Maytag microwave oven, model # MMV5207AAB works great and looks new but I just tested it and found it emits a huge amount of microwaves out the front. Would this problem be solved by my putting another plastic covering over the existing one on the inside of the door?

It could easily be a bad line fuse and/or line filter. To access you will need to unplug the unit and remove the outside case. Inside the unit, where the A/C power cord comes in, there should be a small circuit card (part #237068) located somewhere with a fuse mounted on it. This is your input line filter board with line fuse. Replace the fuse, first and see if this fixes your problem. This is a 20amp appliance fuse that you can purchase at any hardware store. Make sure you place the cover back on the unit BEFORE you plug it in. It is not safe to have this area of the microwave exposed with power applied. High potentials in the 4,000 volt range are present! If the fuse does not correct your problem, the circuit card runs about $26.00. Good luck and hope this fixes your problem.

Typically, no heating of food, indicates a bad Magnetron (tube) or associated components. The oven can be repaired. Magnetrons are not hard to replace and can be ordered online through MCM electronics www.mcmelectronics .

However, due to the dangers of high-voltage within the unit, I would recommend taking the unit to a repair center.

Look in the manual to see what the warranty says. See if there is any information regarding the magnetron or parts. You may be able to get it repaired for free parts, less labor.

Please let me know if I can be of further assistance to you.

Good Luck,

THE DOOR ON MY MAYTAG MICROWAVE OVEN HAS A SCREEN OVER IT. I HAVE SOME FOOD SPATTERS THAT PENETRATED THE SCREEN AND I CAN'T CLEAN THE GLASS THAT THE SCREEN PROTECTS. HOW CAN I REMOVE THIS SCREEN TO CLEAN THE GLASS?

With the symptoms you have, I would most strongly suspect a shorted high voltage rectifier diode or a bad magnetron, or a loose and possibly corroded connection on the magnetron's terminal.

The diode is a fairly cheap fix, and the mag will cost more.

If you or someone you know decide to look into it, we have critical safety information and disassembly information at our site, and our link is at our listing here on FixYa.

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.

If you don't find yours, or if you want to look at it without disassembling the oven, you can download it here.

Here are some links you or someone you know can use for test help, but read their safety warnings first:
