My GE JES1855PCH04 Appears to work except the actual heating process?
The entire oven appears to be working except for the actual heating process .One can hear a clicking sound when the heating is supposed to begin.
Here is a link that should help with your problem. Concentrate on replacing the magnetron as I think that's your problem. Ralph
I have repaired more than one microwaveand find that it generally is not the magnetron tube that goes bad. What usually happens is simply a blown fuse. This repair involves taking the cover off and finding the circuit board.Even on cheap ovens the fuse is usually in a holder instead of soldered in so it is simply a matter of either checking for continuity in the fuse with a multimeter( this will tell you if the fuse is the problem) or removing it and taking it to your local Radio Shack and having them find you the correct replacment, snapping it in and reassemling the unit. Hope this helps.
Fuses always go for a reason BUT very old fuses have been known to just fail because of inrush current like my 30 year old GE microwave!
