So is it dead? (No life, no beeps, no lights?)

A microwave can be dead for many reasons.

If it goes dead for a while during or after cooking then comes back on, the magnetron is probably overheating and causing the thermostat to open.

When it cools, it closes the circuit and allows power through again.

If it's random, it may be a bad connection, usually on the control board or fuse holder.

If it went dead almost immediately after pressing the Start pad, that's usually a shorted high-voltage capacitor.

If it went dead a few seconds after pressing the Start pad, that's usually a failing high-voltage transformer.

If the fuse is good, it may be an open thermostat or thermal cutout on or near the magnetron or on top of the cavity / body of the oven.

No power to the oven.. outlet that it is plugged into is ok. is there an inline fuse or could the power supply be bad?

There are two fuses inside the unit, a high voltage fuse as well as a slow blow fuse, you may need to replace these, but as well as that you may need to check the high voltage capacitor as well as the transformer if replacing the fuse's dont solve the problem. Good luck.

Remove cover. Check that the fuse is good, if it is good, check power from power supply to main board.

GE MicroWave JES1136WL01 died while defrosting.

Mine has the same problems. After removing top cover, check fuse on power supply board (mine was OK). Then check thermo fuse located to the far left under the top cover( 2 black wires going to it) using a meter. I then jumped this fuse to see if this was the only problem. I hope to find a replacement thermofuse at the local hardware store.

Check your main breaker fuse in your panel/subpanel.

Otherwise if the inline fuse is good and the main power is good, then look at the power supply for the microwave.
