Microwave dead no power - GE JE1860 Microwave Oven

The control board may have gotten wiped out by a recovery power surge.

If the fuse is blown the microwave will be "dead". The fuse is accessed by removing the cover. You can usually find the fuse by following the power cord into the microwave. Unplug the microwave and don't touch anything except the fuse as the capacitor can hold an electrical charge.

there could be many reasons for your microwave to be dead. First did you check if it has power coming to it? Is the plug out of the socket? Sometimes the power plug is behind the microwave and it is hard to see unless you slide it out and look. When you say dead, is the display light up? If so does it indicate PF (Power Failure)

Sometimes the internal fuse blows out because of a short, usually caused by the diodes being shorted or even the transformer or the magnatron tube itself. If you have any of these problems except for the fuse then I would recommend that you replace the microwave with a new one because yours probably wouldn't pay to fix.

Good luck,

If it is completely dead, check the main fuse, which is likely a AGC ceramic type. If dead, you can buy from Electronix: http://www.electronix.com/ and click microwave in the left column. Good luck with it.

Sounds like a blown fuse. Carefully remove the cover, and the fuse in directly behind the power cord on the top. Radioshack sells 15A ceramic replacements.

This is most likely a dead magnetron (microwave production) or a dead transformer.
These are the most expensive bits of a microwave, so unless it is of sentimental value, a new unit is actually cheaper than a professional repair.

the kliestron is most likely bad or the stertup solenoid is stuck. also could be the control module needs replaced...

Check the fuse in the bottom of the oven ... near where the power cord enters.

check the fuse inside, watch out with those can capacitors as they can give you a nasty shock. For your protection unplug the microwave and wait 24 hours to let the capacitors discharge, then open and find fuse which is usually near the power supply, check fuse, if dead replace it.
