SOURCE: RCA Microwave stopped working
it probably just died they do that sometimes. you could take it back to the store you bought it, contact RCA or just throw it out and replace it with another.

The first thing to try is a "hard reset". Unplug it from the power line for a few minutes, plug it back in, set the clock, then try again. Let us know if the hard reset doesn't fix it.
If not, then you may have a problem is on the control panel, which we repair nationwide for $39.95 postpaid.

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.
