JT930BH1BB General Electric Microwave Oven Combo - Instructions

The oven lamp shattered while cleaning. Easy to replace by hand.

First of all, there are FOUR panes of glass on the oven door and two different sizes. Make sure you're ordering the right pane. We initially got the wrong one and had to return/reorder.

Took door off hinges and set on table. Removed almost all screws. Two at the top are very long and almost spring loaded -- this was helpful when putting it back together.
When removing the layers, keep track of what/where screws are placed. Some are star-hole-head, some are hex-head (socket). Work slowly and carefully so as not to break additional panes of glass. Leave plenty of room in your workspace to set items aside while you get to the innermost part of the door.

For this part #, it's deep in the door layers and surrounded by fiberglass. Wear gloves so you're not itchy later. This part acts as a double-pane with a narrow aluminum frame around the two pieces of glass. Be careful not to bend the frame when removing the broken piece. One corner of the frame also has a hook-n-hole closure. Take care to not bend the hook too much.

We wiped all the glass pieces off to get all fingerprints, smudges, and baked-on foods removed. Then we put the pieces/parts back -- a lot like a puzzle. Had the oven back up and running with no problems. It may take two people to get the door back on the hinges just because of the weight and awkward position they need to clamp back together.

Before you get started on this be sure that you already have the Bottom Cabinet Trim Assembly (item #PS952490) either ordered or installed. We were not aware that you had to order both trim items separately which meant we had to remove the oven door twice. Using the screwdriver to pull back the door tabs, we first removed the oven door. The trim installed very easy. We just lined up the holes, pushed in, and then down on the trim to lock it in place. When reinstalling the oven door, be sure that door latches are almost fully extended before reinserting them into their slots.

** You must have a T-20 security torx bit to replace the element. I used Sears Model 25702 **

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

Remove the back cover screws and remove back/top. Locate the thermostat and remove the two Phillip screws. Cut off old scorched terminals and replace with new terminal connectors on the wire ends and install new thermostat and reassemble.

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.

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.
