Replace the fuses

Replaced the fuse. Result; did not fix the problem.

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.

Ordered new probe

Convection fan came loose from the shaft with a lout rattle and grinding as the fan spun down. Had to remove four metal screws to remove the fan cover. Initially tried to just put the nut back on to hold the fan. However, I could not get the nut to start, so I assumed that threads were stripped on the nut or the shaft. Ordered the replacement nut, hoping that it was the nut that was the problem. However, I had the same problem with the new nut. I could see no damage on the shaft. It finally occurred to me that the nut and shaft had left-hand threads (counter-clockwise to tighten). At that point, it was extremely easy to put the nut back on and tighten it. I did not try using the old nut, since I had already received the new one, but I'm certain that if I had come to that realization earlier, I could have saved time and money. So, if you have the same problem, try putting the nut on "backwards."

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

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.

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.

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.

Just like the directions said. Very simple.

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.

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.

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.
