It could be that the magentron has failed. Does it make a loud hum or buzzing noise when you try to use the microwave only function? If it does, chances are that the magnetron has shorted out. The replacement cost can be as high as the cost of a new oven, so it rarely makes sense to fix.

How do I use the grill function on my new microwave?


I've had an Emerson microwave/grill for about 5 years now and love it!! To use the grill function you just hit "grill/combo" then hit the buttons up above the grill/combo button for however many minutes or seconds you want, then hit "Start" button. make sure your using a metal dish.

There are large transformers that supply the high voltage needed for the microwave to work. They are normally what goes when they stop working. You need a high voltage meter to check them. A tech. that is equipped for microwave oven repair may be your best bet.

Microwave HT85G650B keeps switching off after 2 secs when on microwave setting but works okay when on grill setting


grill circuitry is not the same as microwave circuitry. The microwave function relies on a magnetron to excite the water molecules in your food. The magnetron and high voltage diode are not working and need to be replaced.

Microwave blows fuse in microwave mode grill function ok


It is most likely the capacitor has shorted or the rectifier has shorted. Check with ohmeter, but make sure it is discharged first by shorting the capacitor with a wire.

DMX31 microwave does not work,grill, light, timer ok


its likley to be the magnatron burnt out, (the bit that makes it cook!)
its a very pricy part to buy and you cannot fit it yourself without putting yourself in danger doing it,, (like killing yourself!) so if you wont to get it fixed drop it into the shop or if its a fuw years old or more its a better bet to just buy a new one

My Ge SpaceMaker XL1800 Microwave Oven won't power on any more.


1.Check power outlet for working.
2.If it is than you have broken fuse inside the m/w.
3. To change the fuse you have to disconnect the power to m/w, take the upper grill off, take the screw on top of control panel, lift the control panel up and removed. The 20 Am fuse located behind this panel.

Smeg fmc24x oven and grill work turntable and microwave dont


I have a simular model and I found that the circuit board has three black relays, one for the grill one for the convection and one for the microwave. I found that the microwave one wasnt working so by swaping the microwave one with the convection one I got it to work and then replaced the faulty one with a new one at a later date.

Bad power diode, bad power capacitor or bad magnetron

Google on 'microwave not heating' and you'll get some sources of information
