check your thermal fuse its about 2 inches long white on the outside black on the inside it has 2 wires going to it check for
cotinuity becareful of the capacitor you need to disapate that first by touching the two teminals together with a screw driver

SOURCE: Bought Emerson MWG 9111SL Combo
it should have it inside the box when you bought it new. if there is none, go back to the place where you bought it and they would be glad to give you a copy of the customer's operating manual. i hope i was able to help

Hi, I take it that this is a combi microwave? Some of these have settings on the front to microwave/grill/etc... so make sure its on the right one first!!
If you have selected the correct one then the m/wave does not work it could be several things!
Microwaves run to earth and need diodes to do this if these break down it will not m/wave! It could also be a internal fuse? ( but very unlikley if everything else works) Then you have the Mag or transformer which could be down to! M/waves run on a high power side and a low power side. The low power will not hurt you to much but the high power side will. My advice to uou is not to touch as it could be fatal as these things carry a high charge even when they are unplugged!

Chances are if the varistor fails, it fails drastically causing a short circuit across the supply. It will sit across the supply (it will look like a thick ceramic capacitor) and you can check for continuity after isolating that at one end. If it shows low resistance (it should show almost open circuit with a Digital meter), replace it.
It need not be the culprit. If you are familiar working with High voltage circuits ( they are lethal inside a microwave ovens as the current capability is high here), you can discharge the doubler capacitor and isolate the high voltage diode to check for shorts in the HT area.
