JKP90DP3BB General Electric Microwave Oven Combo - Instructions

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.

remove two bolts in on sensor and slip thru back un plug and reverse to put in

Removed oven door. Removed 2 screws from heat sensor on rear upper wall of oven. Pulled unit out to access rear of unit. Removed six screws on shield on back of unit. Dis connected heat sensor wire and pulled old sensor through from inside of oven. Feed wire of new sensor through from inside and plug in. Everything in reverse. I also had the gas(propane) company come out and check the pressure coming out of the "low pres." regulator. It was low, they changed the regulator.

Disconnect the range from the mains. Open the door. Remove the single screw holding the temperature sensor - this is located on the back wall on center and is screwed to the broiler mounting plate. Remove the four screws holding the boiler element and allow it to hang down on the wire; this exposes a space to feed the wire through later. Now move to the back of the range and remove the six screws that hold the central cover plate. Now push the insulation to up out of the way and you can disconnect the temperature sensor, pull it out through front, insert the new one and connect it. Reassemble in the reverse order. Mine worked perfectly!

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.

Followed the instructions that were sent to me by E-Mail.

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.

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.
