MICROWAVE WONT HEAT

Hi, every function on my microwave seems to work alright, but the microwave wont heat anything. I replaced the diode. The magnetron passes the continuity test, however, it makes a rattle sound when the microwave starts to run, and the microwave still wont heat. What could be the problem? Is it possible for the magnetron to still pass the continuity test, but not be able to produce the necessary heat? Could it be the capacitor and how would I check it to verify without having to take it out and replace it. By the way, I found one fuse, and it too passed the continuity test. Are there any more fuses?It's a whirlpool model- MH1150XMB-0, Serial #TR R 23 42972,
CAN ANYONE HELP PLEASE?????

GE Spacesaver ii has power, but won't heat


Look for a blown fuse in the high voltage area for the magnetron. Usual problem is a shorted HV diode. It could also be a shorted 'stirrer' bearing (a metal fan-like device mounted near the top or side where the microwaves exit the metal wave guide into the cavity). The bearing is plastic and you can't see the arc path because it is inside the bearing--replace the stirrer. Fairly simple fix, but time consuming.

Microwave seems to work but doesn't heat up


HI, when the Magnetron becomes unstable, the microwave will not heat anything. simply replace the Magnetron. This device creates the heating action and it is damaged and not functional at this time.

Whirlpool Gold Accuwave wont heat


Hi, there are three issues that will cause a no heat situation in a microwave. these issue are a failed Magnetron, busted cut-off fuse and, failed diode.

I recommend checking all these area that are located inside the microwave for faults.

The most common issue will be a failed Magnetron.

The diode and, fuse will be located on the noise filter assembly.

It doesnt matter how old a system was. components can be failed at any point in time. unplug the unit. carefully disassembly and visually check the diode near magnetron and capacitor, it might be broken.If seems good, check the thermostat continuity,if beeping. changage your magnetron. be careful capacitor store charges that deadly. discharge the capacitor first.
when you change mag. change the diode too.

Wont heat


If the diode is good (not shorted) then I would suspect the magnetron.

Here are some tests that might help:
