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.

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

It may be an open fuse, magnetron TCO or oven cavity TCO.

Accessing the oven cavity for testing and possible replacement will require you to remove the oven from the wall.

If so, the installation instructions are very handy, and it's best to have two people since the microwave can be heavy and awkward.

Maytag Model MMV1153AAW vent won't turn off; we have to unplug it and plug it in to use it so the vent won't run 24/7. When we plug it back in to use it, the vent comes on within 15 seconds and might shut...


Hi,
Either your thermostat or relay to the blower has faulted. Thermostat is cheap but the relay is on the control board. So either replace the thermostat P#53001373 or replace the microwave as the control board is discontinued according to the information you provided. Good Luck

My maytag microwave wont heat up food> model #MMV1153AAW, serial # 10394151EN


HI. Your symptoms are a strong indication Magnetron failure. This is the principal heating device, that is used to produce microwaves that , essentially, excite the water molecules in the food, thus, producing the heating effect. When this device fails, generally, the unit will run, but not heat. This device is very fragile, and can injure you if you are not qualified to handle this type of component. There is a High Voltage Capacitor, that is used to help provide the necessary current for optimal Magnetron operation. This capacitor must be discharged correctly. If not, you could risk serious injury, during the repair, if it is accidental touched.

The Magnetron is linked to a cut-off fuse. If the magnetron becomes unstable, this fuse will shut the device down. It is standard procedure to have this fuse test for continuity. If the fuse has blown, this will be the culprit. Replace the fuse. Now, if the fuse continues to show continuity, this will confirm that the Magnetron has failed. I would advise to inspect the Capacitor, and HV diode for visible burn marks, or swollen top(Cap).

Access can be ac hived to these parts by removing the outside cabinet screws. Once the screws are removed, the cover can be removed, as well. Once the cover is removed, the internal components will be exposed for testing, and visual inspections.

WARNING: IF YOU ARE NOT A QUALIFIED SERVICE TECH, THIS WILL NOT BE A NOVICE DO IT YOURSELF JOB. MICROWAVES ARE VERY DANGEROUS, AND CAN CAUSE SERIOUS INJURY. I RECOMMEND TO CALL FOR SERVICE, IF YOU ARE UNCOMFORTABLE WITH HANDLING THE CAPACITOR, OR MAGNETRON.

It sounds like the magnetron may have either failed or is not being supplied with the extremely high voltage required to run it.

YOUR SAFETY IS PARAMOUNT

This is a job for a professional but if you are safety clued up, here's instruction.



If it is the type with an "Invertor", they are not user serviceable and should be directed to an authorised repair agent for continued safety, otherwise if conventional;


Make sure the !!!!any capacitors are discharged!!!!! before attempting any sort of repair.
Check the door interlock switches first then the high voltage diode with either an AVO model 8 or moving coil meter on high resistance range for short circuit, (DVM's won't show the fault!), the capacitor can fail and go short circuit, the feed fuse on the primary of the high voltage transformer and then finally, the magnetron is best checked by substitution.
Hope that helps.

Unfortunately, if you have cut a wire internally then any warranty will be void.

Have you investigated why the transformer is sparking? This sounds like either a serious problem with the transformer or simply a loose connection.

I assume when you cut the wire you have made sure that it is insulated from the chassis?

No power to the oven.. outlet that it is plugged into is ok. is there an inline fuse or could the power supply be bad?


There are two fuses inside the unit, a high voltage fuse as well as a slow blow fuse, you may need to replace these, but as well as that you may need to check the high voltage capacitor as well as the transformer if replacing the fuse's dont solve the problem. Good luck.

Maytag mmv1153aaw ehaust fan turns on


Normally the hood / exhaust fan comes on when you turn it on, or when the temperature at the bottom of the microwave gets high enough to close the hood thermostat.

Sometimes a failure of the hood thermostat or on the control board can cause intermittent or unintended operation of the hood fan.

A thermostat can only trip so many time before it fails permanently.

One way to test it is to unplug one wire from the thermostat, tape it up to prevent it from shorting, and see how it acts for a couple of days.

If it stops failing, the hood thermostat is bad., If it continues to fail, chances are you have a failure on the control board, which we can repair for $39.95 in most cases.

I have the same problem with mine!!! I spent 58 dollars to have a 6 dollar diode replaced. Now 8 months later... same prob. Replaced again myself and working fine again. Just make sure you label the wires while working on it. I didn't and it cost me 2 new fuses! Hope this helps.
