While using the oven in bake mode the temp went up and went to self clean locking the oven on its own. I turned off the oven and the display read F 02 and then the oven died. We have tried replacing the oven sensor and the central oven control with no results. What do you recommend for this problem. Thanks

Thanks Donna, What exactly is wrong, do you still have the code, is the control not working at all, etc. What parts did you replace(part numbers please). I've attached the fail code and the checks to make, from the service manual, and want to check, for proper parts orderred. F02 Welded element relays
With the control power off, check continuity across P4-1 or P4-3 (both are L1) and the
following connections:
P5-1 for the convection bake element.
P5-2 for the bake element. P5-5 for the broil element. I think, you may have needed this part, and not the control board.Part number: AP3873481
If you do the tests I gave above, the wiring is OK, then you should seriously consider repalcing the part.Good Luck, :) :) :)

Just to add my 2 cents... The explanation of the error code and the troubleshooting procedure posted by Joe is absolutely correct but there are two control boards in this range. The first control board (#5 on the diagram) is the User interface control board and the second control board (#24 on the diagram) is actually the power relay board. The real suspect in this situation is the relay board and only this board has the P4 and the P5 terminals. - The relay board Part number: AP3753720

The parts that we have changed so far are ap3873481, ap4321511, ap3753720, ap3968801, and there still is no pwer to the display or the oven. Is there any other solutions for our problem? We replaced each part separtly and then tried with all new parts with no change. The original problem was the oven was in bake mode and the temp rose to activate clean mode. We turned oven off and the display read f 02. after that the oven never responded. What is your recommendation. Thank you Tony. mod #kdrp462lsso7

Tony,
Is the display blank and you can not input any command?
If this is correct, you may want to check the voltage at the terminal block (behind the rear panel). It suppose to read 120 VAC between each hot line (black or red wires) and neutral (white wire). and 240 VAC across the red and black wires. If the L1 (black wire) is missing or the voltage reading on this line is less than 110 VAC while the L2 is correct, then the surface burners and their ignition will work fine but the oven controls would not.
Gene.

The display is blank and cannot input any command.There is 240 VAC to the terminal block and also the burners and their ignition are working fine.
What else could it be?

How did you know there is 240 VAC? Did you measure it?
You already spend a lot of money for unneeded parts (like the oven sensor) because of guessing. So every single troubleshooting step must be confirmed instrumentally.
Gene.

I used a multimeter and read about 240 VAC. Any other solution. Tony

Tony, After doing some research I found that there is an inline control panel thermal fuse which is wired into the wire harness from the control power transformer to the relay board (one of the two wires to the P3 connector). Sounds like this fuse is open. - The control panel thermal fuse Part number: AP3872581

Thanks Gene. The thermal fuse solved the problem.But what would have coused the fuse to go. Tony
