PT970SM4SS General Electric Microwave Oven Combo - Instructions

Sensor is in rear and on top ov oven. What could be a 10" job took 45". My problem was the oven door was diffinately in the way. Also I wear bifocals which makes me tilt head to see nuts. I felt like a contortionist. HINT: remove door and give yourself some room to work.

twisted it in place

1) Shut off power to oven
2) Removed oven door using snap down hinges on door
3) Removed 4-phillips head screws holding the oven frame to cabinets
4) Pulled oven out of cabinet and set it on stool in front of opening
5) Remove 2-hex screws holding metal shield covering the electrical wiring on back of oven
6) Unplugged bad thermostat connector
7) Removed the single hex screw holding thermostat inside the oven
8) Pulled the thermostat and lead wire from oven
9) Fed the new thermostat wire into inside back of oven
10) Reverse steps 1-7

Removed torx screws for door handle as well as torx screws for both hinges to separate the door halves to extract broken glass and to install new glass panel. Other reviews said not to remove hinge screws, however I had no problem reinstalling them.

Removing the oven from the wall to rest on 2 chairs was pretty easy. After that, if I only had to replace the convection heating element at the back of the oven, it would have been a snap.

However, getting access to the main heating element on the bottom of the oven was really difficult. There were no instructions to follow, so one can only look at what is available for similar units online, but my attempts to remove the inner oven shroud on my 14yo wall oven could not be done without major bending.

So, I tried to get to the bottom heating element by removing the bottom of the oven, only to find there to be another layer and another layer, and then insulation that wrapped around the sides below that after taking off the sides.

By the time I finally got to the bottom heating element on my old oven, my patience was gone and I decided the jigsaw puzzle created by this vain effort was not worth putting back together. Better to opt for new technology.

While PartSelect is easy to work with, had I known this project was going to be super difficult, I would never have tried to take the old oven apart. Some engineer needs to be spanked over that design.

Lesson learned on replacing the lower heating element on a wall oven where the unit has to be completely disassembled, don't.

The money spent on freight, fees, and return postage will be chalked up to experience.

Took the oven door off and removed the inner door panel, put new glass assembly part in and reassembled. The hard part was getting the door hinges locked back into place.

Removed the outer cover to access the door switches. Turns out there were three switches, but I determined that only two were bad. When the small colored tab on the switch is pushed in it should make a clicking sound. The two bad switches had no resistance and did not make any noise when pressed. Removing the switch is relatively easy, you simply pull it away from a couple small tabs holding them in place. After reconnecting the wire leads, insert back into the holding tabs and install the cover.

This is sometimes described in other repair notes as "microwave 'runs' when door is open."
With power disconnected: Remove the microwave's metal grill surround. Three lower screws accessible with lower oven door open. Two screws accessible at top of microwave door opening with door open.
Remove microwave control panel: Remove two femaleTorx head screws (#27?) that secure the panel, accessible at right side of door opening. The right side of the control panel is secured by plastic tabs fitting into slots in the oven frame. Take good care to note how these tabs disengage from the slots (lift and shift). Tab breakage very possible! Once disengaged, the panel hinges outward and downward and is self-supported. It may be necessary to guide some of the wiring out of the way to fully lower.
There are three door switches, one "monitor" and two "secondary" switches. All switches are housed in a plastic frame, which must be lifted out of position for access, each switch is retained by flexible plastic, breakable-looking hooked fingers. Also note that the electrical connectors have tiny release tabs that must be depressed in order to pull them off of the switches. In my case the topmost switch, one of the "secondary" switches, was clearly bad since there was no "snap" or click when pressing the switch's button. Maybe you can determine which switch is bad before proceeding but I had ordered all three to avoid going through this exercise again any time soon.
Replace switch or switches, place switch carrier back into position and otherwise reverse the disassembly steps.

0. As a safety precaution, unplug the range or hit the relevant fuse breaker before you start. You might also want to grab a flashlight. Definitely do not try to do this while the oven is hot.
1. Pinch the wire over the light bulb cap to remove it. This is inside the oven at the back.
2. Pop off the hemispherical glass cap.
3. Unscrew the old light bulb, and screw the new light bulb in its place.
4. Put the cap back.
5. Secure the cap by putting the wire back in its slots on the cap.

No tools needed, the cap is just held in place with pressure from the wire.

Pulled it from the wall remove the front vent covers removed the control panel remove the door switches by a special screw driver bit which looks a star remove the electrical terminals pressed the plastic clip pulled the switch replaced it with new one then followed initial steps backward

Remove the ice bin.
Turn the ice maker selection to "OFF"
Use small flat blade screwdriver to open the plastic ears on the electic plug in connectiion
Use #2 Phillips screwdriver to remove the screw on the front left side of the ice maker
Pull the ice maker forward until free of the two studs in the left side rear of the freezer wall
Check to see if the supplied water chute is the correct size for your application, if not remove the water chute from the old ice maker and place it on the new one.
Place the new ice maker in the freezer connecting the slots on the left read with the studs on the left wall
NOTE; IF THE ICE MAKER DOES NOT APPEAR TO BE LEVEL HORIZONTALLY REMOVE IT AND CAREFULLY REINSTALL IT TO ACHIEVE LEVEL
NOTE: ENSURE THE WATER DELIVERY TUBE RESTS IN THE RECEIVER TRAY
Reconnect the electrical plug ( needle nose pliers may be helpful in aligning the male plug with the female plug)
Move the selector from "OFF" to "ON"
Replace the ice bin and close the freezer door

RE: 2 yr. old GE double wall oven with convection option in upper oven, non-convection in lower oven: baked goods were not browning, were undercooked or burned. Tested both ovens on regular bake setting using 2 oven thermometers. Set ovens for 350. Although after 10 min both ovens beeped "ready", the oven thermometers actually read 200 - then would swing up as high as 500 and as low as 200 during the 20 min test period. Decided to first replace top oven sensor only, just in case it really was a more expensive control panel problem. It was a bit awkward to reach back there with the oven door in the way, but I have long arms! Aimed my flashlight, removed nuts with a socket wrench, pulled out the sensor, popped the clip and the old sensor easily separated from its connection. Snapped on the new sensor, pushed it back in and reset the nuts. Easy. Set the oven for 350 and tested again with 2 oven thermometers for 45 min. Voila! The oven thermometers read exactly 350 when the oven beeped "ready" and it stayed at 350 throughout the entire 45 min retest period with only a 3 degree variation both up and down. What a great improvement! Immediately went online to Parts Select and ordered another sensor for the bottom oven which was having the same problem. Fixed both ovens all for under $30 - and just in time for Christmas cookies! Don't want to know what the repair guy would have charged.......Merry Christmas!

Removed back panel, change out sensor

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.
