This does not answer the question of how to access the front panel without messing up the woodwork around the panel. I already understand the difference between F1 and F3. I wish to check the front panel connections first, because I don't believe there is anything I can do in the back other than replace the sensor, and I do not believe the sensor is bad at this point.
well you have to pull the oven out about 12 inches to remove the control panel. This is not an easy oven to remove if you do not know how. You need to install a small flathead screwdriver on the right and left side of the oven between the control panel and the trim (door is open)
This screwdriver will fit between the wood and the fram of the oven (left to right) and the control panel and the cavity (up to down)Push the screw driver in about 2 inches and push in TOWARD the oven cavity to push a spring clip mounted on the wood frame. You have to do this on both sides of the oven.While someone is pushing on the spring clips, someone else need to pull the oven out. It's hard to discribe but that's how you do it.
I'm trying to understand this, but I don't even get the first part about pulling the oven out 12". How do I do that with my primary problem now being getting the oven away from the cabinet without messing up the wood? I'll still have further questions regarding getting to the control panel.
I've been trying to get back to this, but haven't had the time. You said I could continue asking questions along the same line without being charged more. A few days ago I re-read your first response and you said I could check the wiring back to the control panel, but that didn't sound like my problem, but you said my clock does sound like the problem. You have my attention now on this, but I'm at a loss as to how my clock can be the problem. If you have a realistic fix in mind, I'm all ears.
I'm only replying because I've determined the problem, and I think the solution might help you help others.
The problem was a cold solder joint on one of the RTD sensor pins on the controller board. On that point, you were correct, despite my inability to accept it.
As for the access to the controller board, I think you were way off. The oven has to moved almost completely out of the cabinet in order to remove the 5 screws that hold the top on. Once the top is removed, the controller board is accessible, and can be removed by taking out 4 screws from the inside. Access to the 2 controller boards requires removing the circumferential enclosure which is not immediately obvious how to perform.
Small flathead screwdrivers are not needed and spring clips do not exist.
