Test this steps and fix it. GOD BLESS YOU


  1. Controller is confusedA power surge or random non-reproducible action of the universe may have resulted in the controller's program ending up in an infinite loop. Pull the plug for a minute or two to reset it.
  2. Defective Interlock switchesThis can result in the controller thinking the door is open and ignoring you.
  3. CleaningCleaning solutions (spray cleaner) may have gotten inside and shorted out the touchpad or controller. If this happens remove the touchpad, let it air dry for a few days, and then attach it back on the microwave.

Maytag microwave mmv4205bas key pad is not functioning properly


It could be that the buttons are worn out. You'd need to replace the keypad to fix it, which will likely cost about as much as a new microwave. See if you can get it fixed under warranty, also, try cycling the power, it's always worth a shot.

The problem is more than likely in the keypad control board, pricing on this part should be checked before going ahead with repairs.

Screen displays -SE- , none of the keypad buttons work


The word -SE- , means systems error, the cause is a short in the membrane of the keypad. The only solution is the keypad must be replaced.

Maytag MMV4205BAS OTR microwave does not vent internal steam and the microwave shuts off. It takes about 15 minutes to reset and power back up. What part is bad?


I have this same microwave, and I'm having trouble with it shutting off. It use to go back on, but now it doesn't work at all. I tried replacing the two fuses under the panel, but that wasn't the problem.

After some research and calling vendors, I believe the issue is most likely due to a failure of the magnetron tube which supplies the microwaves. Take it to a repair professional to get a cost estimate on fixing.

This model of Maytag seems to have BIG problems! It's either the tube is out, the turner doesn't work, or it just goes dead. Usually it's after 2-4 years of service. Poor quality... Maytag lost a lot of clients with this product!

MAYTAG MMV4205BAS Running but not heating


If the food in the cooking compartment is not heating at all, then you may have one of several components related to microwave energy generation that have failed or became disconnected internally.
Magnetron Tube, HV Capacitor, Filament Transformer or any number of sensors that disable power to the system. The control board could also cause the system to noty function correctly.. You wanted general inputs.. there ya go.. LOL
Not sure I told you anything you didn't already know but you should ask the tech what he did after he gets it going...
Regards,
Rick
