Maytag mmv4205bab continues to run after time is up. The fan does not circulate, but it continues to heat.

The main difference between a convection oven vs regular bake oven is how heat is circulated. A convection oven has a fan that continuously circulates air through the oven cavity. Because air is continuously circulated, convection ovens produce a much more consistent and even heat than regular bake ovens.

One of the micro switches has malfunctioned, and must be replaced for normal operation.

There are a few possibilities, the magnetron is defective, or the high voltage capacitor or diode/or inverter board if microwave is under 7 years.

maytag microwave model # mmv4184aaq operates normally but will not heat food or water

When you press start d you hear a click? If not the relay on the control board for the High Voltage section is not working. If yes then I would check the MAG, the Cap/Diode or the Transformer. Eric

try the fuse

My LCD read is dead. can not read any numbers.

Sabotaged??? What could they mean by that?? It could be a bad control panel or connection, but I would say you have a bad magnetron, the magnetron is mounted loosely, or the RF gasket (mesh washer) on the magnetron is missing, loose or damaged. I would contact MayTag and see if they have a different authorized servicer in your area, or get on the phone and complain to them in great detail. Do not put up with this, please.
