JTP90BM2BB General Electric Microwave Oven Combo - Instructions

Opened the microwave oven door, unscrewed two screws which held the control panel on, then I removed two of the door switches (each had two screws), and then used the continuity tester to see which one was not operating. It turned out to be the secondary door switch, replaced it and to my amazement, the microwave worked. I have never repaired an appliance before but I didn't want to replace our over-the-stove built in microwave. It was the best day ever when it was working again! The hardest part was getting myself to try the repair.

Watched How to repair a Microwave that turns on when the door is opened Video on the web. From this took a shot at the switch was the problem. When I removed the switch it was defective. The small button was in and when you turned the switch upside down the button would drop back into position. Ordered a switch for $25.oo , installed it and the microwave is working 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.

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

I feel like Macho Mom. I called in the repair guy since I was afraid of dealing with the gas. HE repaired one item but could tell I was comfortable fixing things and pointed out that the gasket was brittle and would cause major problems if not replaced. Took longer to order the part than do the repair, don't know what I was afraid of!

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 of all, the sensor had the proper ohm reading...at ambient temperatures. I suspected the sensor because it would jump in large degree increments over 200°F. From what I read online, the only other part that would cause this was a faulty circuit board. I opted to try the $20 part first vs. the $200 part. It worked. One screw on the back top of the inside is all that holds the sensor in. Pull the wires out and you will find a quick-disconnect. New part had the same connector (thank you). Thread the wires back through the hole and replace the screw. Works like a champion (verified with an independent thermometer. That is all she wrote. I only wish I purchased two, since they don't last that long... 4 years...or so. I just bought the house built in 2007 and empty for a year... and it took 45 minutes to cook a pizza, and even then the bottom dough was light. A house without an oven is like a hot dog without mustard!

Microwave would not turn on. Lights and fan worked fine. Before the microwave stopped completely, it would turn the microware fan on even when door was open. I read the reviews and they were exactly the same issue that others were facing. Once I opened the front panel and got to the switches it was easy to figure out which switch was bad as it was the one that was soft (When clicking it). It was hard to take it out though (it seemed stuck). So, I used a plier to yank it out. I put in the new switch and everything worked just great! I would like to thank other comments that were left on the site to make my task much easier. Thank you (to the commenters on PartsSelect), you not only saved me money, but also ensured that I learn about the microwave more and give me the confidence that I could fix it.

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.

removed access panal, found soft switch as discribed on your web site. removed and replaced.

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.

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.

Turn off main power bracker. Removed fan vent, removed control panel, disconnect leads to the three monitor switches. Replaced the secondary switch (top). Reversed procedures.

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.
