I have a Maytag Microwave model #MMV5207BAS that will not heat. Displays 8s filled with Xs in the digital display a second or two after you try to start the cooking cycle.

Question edited for a hell of a lot more clarity.
All question need 'make model (what it is)' please, first 3 words.

It literally could be anything. The only thing you can try is a power cycle or check the back for a fuse holder near the mains lead.

Sounds like its time for a new microwave

You can probably buy a new one cheaper then fixing the old one

Most controls that display 888 something is shorted out on the controller.

Have you tried unplugging it for 5 minutes and plugging back in?

H95, H97, H98 or H99 mean that there's a problem with your inverter, magnetron, or digital programming circuit.

Due to the lethal voltages used and produced, I do not recommend that an inexperienced person work on these.

Is there no way this product can't be returned, there should be warranty on the item if new, regardless if it was manufactured in 2007 he has to honour the warranty. The problem you are describing is caused by one or two defective door switches, that must be replaced in order to get it working, and you need a professional that can do the job right.

If it operates as normal but items don't seem to get hot it probably is a Magnatron failure (microwave producer). More times than not the repair / replacement of a Magnatron these days is not worth the investment, especially if the microwave is 4 years old or older ! You should be able to replace your microwave with a similar featured microwave / hood for about $300 to $400. You might try a JVM1750DMWW by GE great micro/hood for about $300, includes one touch sensor cook capabilities,300 CFM vent fan,removable rack,option to turn the turntable on or off, 1000 watts of cooking power. Good luck !

Magnetron and diode most likely. Need more info.

I don't seem to be able to find a Door Handle for my Maytag microwave Model #MMV5207BAS can any body help me. I have tried numerouse sites but the handle does not seem to be available.

A make and model would have been nice, but try unplugging it from the wall outlet for 15 minutes.

Hope that helps...

Need to know the entire model # on the microwave.
