At first error code EO F2 was on display, and keypad was unresponsive. After taking the control panel off to check for loose connections, the oven settings are displaying, but oven won't heat. None of the numbers on right side of the pad are functioning. Does this sound like a touch pad part# 9762100 or a control panel part # 9756548?
Hello. The part number out of the service manual for your touch panel is (white) 9756532, (black) 9756534. From the symptoms you're describing, the keypad is defective--those things are notorious for malfunctioning after a few years due to heat. The error code you got is definitely for a shorted keypad. UNPLUG THE UNIT FIRST. Then, carefully unplug and re-plug the connector on the ribbon from the main board a few times--this will re-scratch the metal pins( they will oxidize over time and break contact)--try this first, if it doesn't work, replace the keypad. Now, when you took the control panel loose, you might have pulled a wire loose from the main oven control board--it's easy to do. Go back and re-check the wires carefully. Here are some pix of the electronic schematic diagram for your range:
Notice in the 3rd pic P2-1 and P2-4 which are BLUE AND RED WIRES, RESPECTIVELY. Look on the oven control board for connector P2...pin 1 is for BROIL and pin 4 is for BAKE. Also, make note of the wire connections on the left side of pic 2--a black wire powering the other side of both the bake and broil circuit. Also, mounted on the rear of your oven, is a thermal fuse, part number 3196548. (note: right side of pic 3, labeled non-resettable thermal fuse) It is a round device, about the size of a half-dollar, with 2 wires connected to it, blue wire with a white stripe, and a red wire. If that sensor is opened, it kills the power to the elements for safety. (And is what trips when people use the self-clean feature)
For those that aren't familiar with how ovens operate:
Whenever an oven is plugged in, 120v is present on the bake and broil elements. When you turn on either one, the main board simply connects the other side, not to ground as in most other devices, but to another 120v on the opposite electrical phase **adding up to 240v** and heating the elements!!
This is why it's so important to **always remove power** before attempting to service an oven or range.
I hope I helped you!
You need the touchpad that you press from the front--that's where the problems start. The thermal fuses are just like any other fuse--REMOVE POWER FIRST!! Then, remove a wire from one side, use a meter set to ohms or continuity(beeps when the leads are shorted) and touch each lead to a side. If the fuse is good, the meter will beep or register almost zero resistance telling you that current can flow across it. If it's open(bad), you won't get anything and will show infinite resistance.

I unplugged and replugged the ribbon several times and the right side (numbers) are still unresponsive, and I checked the red and blue wires and they are connected securely. I don't know to tell if the fuse sensor is open or not. It is just 2 wires going into a black rectangular plug in the middle back of the oven. Can you tell me how to check if its "open"?
Also, another site lists the touchpad part as a different number than you list. The part# 9756534 (I was told it was 9756548), is listed as the control board (with all the circuits capacitors, diodes etc soldered to it. Do I need the touchpad thats visible from the front of the unit or the control board only visible from the back of the unit? You've given me great instructions. Hope you can help me a bit more.
I see that 9762100 cross references 9756534, and is the touch pad. Is this the part I need? See pic
