All Installation Instructions for General Electric Microwave Oven Combo JTP90DP3BB

Timer, light and control pad worked. Turn table and heat did not work. Oven would not start up.

I first read where someone had the same problem. Their solution was a burned-out fuse. I ordered a new fuse...installed it and that did not solve my problem. I revisted PartSelect and read how Marla (from Arlington, TX)solved her problem. I purchased a secondary switch and when it arrived, I made a copy of Marla's instructions and followed them to the letter. I installed the new secondary switch into the secondary space, put everything back together and the oven STILL DID NOT WORK. I had to take the latching panel apart again and test each switch to see if there was another bad one. I found that the third switch was burned out. So I took the new switch out of the second slot and installed it into the third slot. I tested the switches before reinstalling the latching panel. This time everything worked. So I put everything back together, reinstalled the microwave on the wall, tested it again, and everything worked perfectly.

Oven lights were burning out regularly

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.

Not heating

Removed the above stove microhood. Removed the side panels & the top panel. Diode located on right hand side of microwave. Removed with screwdriver & replaced new diode. It's best to get the microwave schematic online to pinpoint location of the part.
