JT965BF6BB General Electric Microwave Oven Combo - Instructions

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!

Ordered new probe

plug in thermistor when needed

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

pull out defective seal with pliers clean area and press new seal into place making sure the spring clips on seal are completely inserted into door slots push ends of seal into holes in bottom of door

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.

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.

Turned off the circuit breaker. Removed 5 screws. Unplugged the heating element and then plugged in the new one and replaced the 5 screws. Very simple.

The actual repair was relatively easy but access to the area in the oven made it a little difficult. Just unscrew 5 screws with a nut driver, unplug the old element, plug in the new element and reinstall the 5 screws. The only thing that made this repair difficult was being able to reach the connectors where you plug in the new element. They are loose wire connectors that don't reach very far out of the element receptacle. It was difficult to hold the end of the connector and plug in the new element because the oven door is in your way. Maybe it is easier if you take the oven door off first?

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 was attempting to replace the broiler element on the oven, but I discovered that the wiring may be the actual problem. I suggest before you order parts for a broiler repair, that you test the wires to ensure that you have continuity. I will have to trace the wires back to the source (the other element works fine) and see if I can find the problem with the current. I will keep the broiler element I ordered until I can confirm that the old element works.

Took about 15 minutes to take the old one off and put the new one on. Not difficult at all.

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."

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.
