JTP90DP3BB 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.

PartSelect had helpful repair instructions on-line which made the repair easier and faster. Unfortunately, there were other problems with the oven that immediately blew the new fuse I had just installed. It was then determined that additional repair would most likely cost almost as much as a new microwave.

A slam-dunk...just replaced the old roller guide with the new one. Simpler than replacing a light bulb and no tools required.

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.

opened the microwave door, removed the glass plate, removed the bad roller quide, replaced with the new one, replaced the glass plate and then closed the door. :)

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.

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.

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.

it was a simple screw in on both ends. no soldering

bought a fuse but that didn't solve the problem. Guess I need a new microwave

Lifted up the glass plate. Put in the new roller guide. Set the glass plate back in place. Repair done in about 30 seconds! Thanks for prompt service in sending the new part. My only regret is that the part was expensive, and I have already replaced it once before. The new part is still plastic so will probably need to be replaced again.

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.
