JTP90SM1SS General Electric Microwave Oven Combo - Instructions

After reading reviews that there was no power what so ever and a fuse replacement will solve the problem, I tried it. Replacing the fuse is very easy (and I am not handy at all). All you have to do is remove the microwave cover from the top by removing two screws, slide the cover to the left and pulling the cover off. Then remove the grill in front of you, by removing one or two screws. The fuse is in front of you, use pliers and be firm but gentle. Replacing the fuse is easy but it did not solve my problem.

Replaced the Oven light housing. Unscrewed the two screws that hold the housing in place. Pulled out the housing and disconnected the wire tabs from the light housing tabs. Slid the wire tabs onto the tabs of the new light housing fixture. (Each tab is fitted to the tab in goes on so they can not be mixed up) Pushed the housing fixture back into place and screwed the housing into place.

I think I could have managed with just the diode but since I had to pull it I decided to replace all related parts per my research. The Magnetron more than likely was fine.

Remove the microwave cover. Requires a phillips screwdriver and a torx security bit/nut driver (there are two security type screws on the back...guess they don't want you to do this at home!). I had to buy the a security bit set (about $7). The diode is easily accessible on the right side under the fan. Requires removing on small phillips screw and unplugging on electrical connection. GE provides some instructions in an envelope on top (after cover removed). There is a warning/instruction to discharge the capacitor before service. This was not a problem for me. Actual diode replacement took 30 seconds. Whole job = 15 minutes.

First unplugged the microwave, took top grill off, took control panel off, took wires off and used color coded tape to make sure they went back in right places, took fuse out and replaced it and put every thing back and it all worked fine and to top it off my wife did it all. So it was pretty easy.

I shut off power to the microwave, discharged the Hi-voltage capaciator and disconnected the wires to it, then removed the screw and bracket that held the capaciator in place. After removing and replacing the capaciator, reattaching wires and mounting bracket, and replacing the 15amp fuse, the microwave woked fine.

turned oven off, pulled oven out from wall, removed back of oven, unscrewed sensor from oven replaced with new sensor, put back on, turned power to oven on, tried oven at 425, my temp. gage and the oven temp matched. a very easy fix.

The door comes off really easily, I just made it difficult by not knowing the trick of rotating the locking lever and lifting, until I almost tolally disassembling the door. The string was to guide the temperature probe throught the back of the new oven. Know that I know the tricks, It would ne an easy job.
