Question about Maytag MMV5207AAS Microwave Oven

1 Answer

I have a Maytag mmv5207aas microwave. It does not work at all. There is power to the outlet but the unit is completely dead. I understand there are internal fuses I can check. How do I get to the fuses? Do I have to pull the unit down from under the cabinets?

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.

You can usually find helpful exploded view diagrams and order parts by entering your full model number here.

It may be the fuse, or the magnetron thermostat (thermal cutout ./ TCO) or the oven cavity thermostat.

The first two can be accessed via the control panel opening, but if you need to check or replace the oven cavity thermostat, you will need to remove the oven form the wall.

Removing it from the wall is ideally a 2-person job and you should have your installation instructions handy. If not, you should be able to find it here.

Be sure to unplug the oven before you begin.

Fan will not shut off


I think the problem is with the switch. If it is closed (i.e. turned On), it will not go off. Try opening the switch box of the fan unit and check to ensure there is nothing in the box that may be interfering with the switch by keeping it closed (completing the circuit). Otherwise, seek the services of a qualifed electrician.

Maytag MMV4184AAW Microwave not heating


If you are looking to repair this yourself (along with assoceated risks) to cut test time in half the first test point would be to check for both live and neutral feed to the high voltage transformer. If you have both live and neutral here then the control circuit is working and the fault will lie within the high voltage circuit.

Hope this helps

Does the digital display light up at all? Is it completely dead? Are you sure it has power? Have you tried another outlet? If the outlet is good and the unit is completely dead, the internal fuse may have blown. You can try to take the cover off (with the unit unplugged) and look for a blown fuse. Try replacing the fuse with an EXACT fuse of the same rating. Try plugging the unit back in again and see if the unit comes back on. If not, you may have a power supply issue or defective Magnetron.

Please let me know what you find and we'll go from there.

Good Luck,
- Jim

MAYTAG mmv4205aab OVER THE RANGE MICROWAVE


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.
