The lower oven will heat to the set temp at first. As soon as the door is opened to put food in it, the temp drops more than 100 degrees and will not recover. The upper oven works fine, as does the cook top. It does not display any error codes.
The first repairman that we called tested the element (apparently he missed the part about "it heats up"), and when that was okay he said he couldn’t test anything else unless I has the schematic for it because "you know it’s all electrical in there"…in an electric oven. Go figure.
The second repairman replaced the sensor. That did not solve the problem. I gave up on repairmen.
My husband and I replaced the control board. Upon opening the back up, we found the schematic rolled up inside it. Found that to be hilarious. Replacing the control board did not fix the issue. We then replaced the relay and the relay/ daughter board. That also did not fix the problem.
I’m about to put it in the front yard and plant calla lilies in it. Anyone else have any suggestions other than "don’t buy GE again"?
