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.

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.

Removed back panel, change out sensor

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.

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

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

Easy

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.

Replaced it

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

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

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.

plug in thermistor when needed
