JTP90SM1SS General Electric Microwave Oven Combo - Instructions

The breaker was tripped but fuse was ok on testing. I kept the fuse for possible future repairs. To access door switches and fuse on this model JVM1850CF001, remove 2 phillips screws at top. Then slide the grill to the left (toward hinges) about 1 cm and it should easily come off forwardly. Remove phillips screw underneath grill attaching the main panel. Lift the panel 1 cm and it will easily come off forwardly - I let it hang by the electrical cords. Now you can see/discharge capacitor(s). Remove 2 star screws inside door to loosen/remove/access door switch frame. 3 switches are held in the frame by plastic tabs - one tab per switch. One is primary and 2 are secondary door switches. I removed each switch one at a time by lifting tab, pulled off the electrical connector and filed the male metal connection on each switch. I replaced the switch with a loose button (loose and didn't click as crisply compared to the other switches) with a new secondary door switch. It was the lower secondary switch. Worked like a charm after that.

-unplug
-remove top and front covers
-unplug wire connectors from heating assembly
-remove heating assembly from metal stand and push out of the way
-remove metal stand from dry
-pull out heating assembly
-install new one in reserve order

Turned breaker off at panel first. Removed three sheet metal screws holding top control panel with 8mm socket, removed the two 8mm nuts holding the locking mechanism in and one 8 pin plug, replaced with new part. Put back control panel and I was enjoying homemade oatmeal cookies 30 minutes later. We were using a toaster oven for months until I found the part from this site. The GE repair guy wanted $900.00 to fix it. The part was only $165.00 from this site. Thanks folks!

replaced it with the new one.

I took the cabinet off and saw where the switch had been burnt. So I remove it and order another one from your company. And I put new clips on it with heat shrinks. We might get another 30 years out it, Although I'm 80 years old.

Removed back panel, change out sensor

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.

Followed GE repair video

Turned the wire protector to the side. Turned out the old bulb and replaced it with the new. Turned the wire protector back in place and I'm like new.
