This is an odd failure for this model, assung yours is a model MH1150XMQ, since it does not have a humidity sensor. So it sounds like you may have a bad kepad or controller, or maybe moisture or grease got onto the board, casuing it to fail. If you or a friend decide to work on it, we have *critical* safety, disassembly, and troubleshooting info at our site, which is linked at our listing here on FixYa: http://tinyurl.com/yzjozk Below is our information on keypads, too: A bad keypad may be worn out due to age, damaged, or it may have gotten wet or otherwise contaminated. Moisture and contamination can be caused by not using the fan when boiling on the stove top (for over the range models), direct spraying of cleaners, by storing the microwave in an unheated garage or shed, or infestation. I warn my customers to never spray cleaner directly onto the microwave keypad, since the liquid can get inside and "lock up" or even ruin the keypad or controller. Apply an alcohol-based cleaner (such as the purple kind) to a cloth (since paper towels can scratch) and gently wipe it off. I suggest to my customers that they NEVER use any ammonia-based cleaner (like the blue stuff) on a microwave, since the ammonia will crack and distort polycarbonate plastics. DISCONNECTING AND CONNECTING THE MEMBRANE SWITCH (KEYPAD) 1. The keypad connection is the green or blue translucent plastic strip that plugs into a connector near the edge of the control circuit board. 3. There are two tiny tabs (one on each side) on the hood of the connector that you can gently pull up on to unlock the connector. Use equal and gentle fingertip force when pulling up. 4. The old keypad strip will lift out. 5. Put the new keypad strip in, making sure both sides are down fully. (If you are not installing a new keypad, clean yours with a pencil eraser or a soft cloth and alcohol.) 6. While holding the strip down, push the connector hood back down to lock it.

Touch pad doesn't work


Your touch pad is connected to your board with a ribbon wire, it has probably come loose. Unplug the unit and remove the face plate. Pull it back and you will see the wire, it looks like a ribbon, push it in tight, replace the face plate and it should work properly. I see this happen all the time.

Cannot unlock the display panel


Elise,

So I'm understanding that the lock icon stays on no matter what you have tried. I would try pressing and holding the START/STOP button for 5-10 seconds to see if it changes. I don't know how long you've been leaving it unplugged for when you do unplug it, but i would suggest at least 3-5 minutes. If these don't work what I would do is either contact the manufacturer or maybe even a local authorized technician. This way they would be able to assist and possibly have some more suggestions or be able to find and solve the issue for you.

-Best regards-

The display on the touch screen is not showing anything but the controls work, how do i fix that?


The first thing I would suggest is a hard reset. Unplug the unit for a minute or so. Then plug it back in, set the clock and try again.

If that doesn't work, leave it unplugged for about 5 minutes.

Otherwise, note your full model from the tag on the unit and check here for more information.

Screen/ keypad seem to be locked


Sounds like the child lock has come on.

This addressed in your owner's manual. but if for some reason you don't have your owner's manual, you can download Maytag owner's manuals and installation instructions here.

Just enter your full model number.

If it's not the child lock,
I would suggest a hard reset. Unplug the unit for a minute or so. Then plug it back in, set the clock and try again.

If that doesn't work,leave it unplugged for maybe an hour. Then let us know if the hard reset does not fix it.

Microwave came on by itself


Yes this is usually caused by the touch assy, but $278 !!!!! Thats kinda steep considering the panel assy is only around 30-60 bucks!!! It will need the touch assy and even possibly the control board, because sometimes the logic IC gets fried and causes "ghost issues" as well.
