PT970SM2SS General Electric Microwave Oven Combo - Instructions

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!

Followed GE repair video

Unbolted temperature sensor from back of oven. Disconnect cable connector. Replaced and reconnected new sensor and bolted back in place. Haven’t had to replace bake element yet, but it’s a major job being this GE Profile oven has the bake element hidden. That’s a new one on me.

Threw the old one out - plugged the new one in. Steak came out just as ordered - medium rare.

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.

-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

took out old gasket and inserted new

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.

Removed back panel, change out sensor

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.

Replaced new light housing.
Thanks to you guys for the prompt response

I first read where someone had the same problem. Their solution was a burned-out fuse. I ordered a new fuse...installed it and that did not solve my problem. I revisted PartSelect and read how Marla (from Arlington, TX)solved her problem. I purchased a secondary switch and when it arrived, I made a copy of Marla's instructions and followed them to the letter. I installed the new secondary switch into the secondary space, put everything back together and the oven STILL DID NOT WORK. I had to take the latching panel apart again and test each switch to see if there was another bad one. I found that the third switch was burned out. So I took the new switch out of the second slot and installed it into the third slot. I tested the switches before reinstalling the latching panel. This time everything worked. So I put everything back together, reinstalled the microwave on the wall, tested it again, and everything worked perfectly.

This went pretty smoothly. Watch the video and just follow along step-by-step and it goes well. It would have only taken about 30-45 minutes (even being careful and slow) but I ended up placing the glass twice (be very careful and triple check that all the insulation gets poked under the housing and none is sticking out). The first time I had a small piece sticking out. (Use gloves for this part so your hands don't itch). The second time I needed to redo part of it is I forgot one of the spacers on the door handle and had to get that in there so the handle worked properly. I also took the time to clean the oven while the door was off so that took some time. Total I probably had 1.5-2 hours into this project but at least half of that was me cleaning and being fussy. This is an easy repair. I'm not a confident repair person and this wasn't difficult. It was a little time consuming but well worth the cost vs calling a repair person or buying a new appliance. You do need to have a specialty star head on a screwdriver but my simple tool kit had all the tools I needed. The oven has been working great since the repair.

removed the glass turning plate. removed the broken roller guide. replaced with the new one. I am very happy with not only the ease of fixing the problem, but how quickly I got the replacement part. I will use PartSelect again!!! And I will tell my friends.
