Question about Maytag MMV1153A Microwave Oven
From previous posts I read that the problem is with the diode, capacitor, or the magnetron. I was wondering if anyone knew how test for the faulty component?
should be a "mini-manual" (tech sheet) hidden inside the unit
control panel or hidden on the left side behind the grille, which is
very helpful when troubleshooting, testing, and locating components.
You can find helpful exploded view diagrams and order parts by entering your full model number from the tag on the oven here.
Here are some links you or someone you know can use for test help, but read their safety warnings first:
(if it's not shorted or burned, it's probably okay)
But if when you start to microwave, if the turntable, inside light and internal light are not on, then you instead have a bad door switch or door switch mount, in which case you should see this:

Microwaves are a quick, convenient
solution to the hassle of preparing and cooking hot dinners. They are
popular appliances with students and large families where food often
needs to be prepared fast. Microwaves use radio wave technology
harnessed through an antenna, known as a "magnetron," to create friction
between food or liquid molecules, causing them to heat up. Some
microwaves can cease to function properly, resulting in the appliance
running but failing to produce any heat.

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