B38HA-4TXW Magic Chef Wall Oven - Instructions

Followed provided video

Watched the video and it was as easy as described. Not many things go as easily as this.

The thermocouple was suspect. It should be super easy- two screws, but the wiring harness would not pull through on my oven. I confirmed the procedure with the PartSelect video which is good. The harness was caught and broke so I had to pull the oven out partially to get to the harness. The sensor did check bad on the multimeter (resistance too high- Google it, I did) so I ordered the part. Once the new part was installed the oven still did not function. So I had to get busy with the multimeter and pull the oven again. On the back of my oven near the wire to the bake element is a Hi Limit Switch which cuts off the bake element if the outside of the oven gets above the preset temperature. Mine was cracked and faulty and had to be replaced. The oven works great now.

I watched the video, which was very helpful...the temperature sensor was hard to pull through the small opening in the upper back left oven corner. On the back wall of the oven was a large removable circle, so I unscrewed that piece and was able to gain access to the wires attached to the temperature sensor and push it through the small opening. I used one of the new connectors, pushed it back through the small opening, screwed it back onto the oven wall, replaced the circle opening and tried the oven again...unfortunately, there was no improvement in oven temperature! My JennAir wall oven is about 17 years old, and I thought I would try this $30 repair prior to purchasing a new wall oven, but it looks like I will have to do some overtime and buy a new oven. Any other suggestions would be welcome.

I ordered the temperature sensor after watching the video and seeing how easily it could be changed out. Unfortunately, they don't tell you that it may be necessary to access the part from the back. When I tried removing the sensor from inside the oven the connection separated before getting to the hole. I tried for 4 days to try to fish out the other end. Finally, I had my brother help me remove the oven from the wall and take the back off at which time we were able to connect the new sensory. It turns out that the wiring is on the upper right hand corner of the oven and the sensor is on the upper left hand corner and the wiring is rather short. I am a 64 year old female and do the majority of repairs around the house myself, but due to the weight of removing the oven I enlisted the help of my brother. After removing from the wall the rest was a breeze. Just wish the videos or written info on the website was a little more clear as to the different ways of accessing the damaged part.
