Question about GE JKP45 Electric Double Oven
The solution applies to most built in GE ovens, but the wire coloring may be different for some models. Make sure you check your wiring diagram that is specific to your model number.
Symptom: F2 errors, oven display stays at 100 degrees, uneven cooking.
Description: You turn on the upper oven and set the temperature. The left orange numbers on the display light up and show the set temperature. After about a minute the left temperature shows 100 degrees and stays there. You check the upper oven, but it is not getting hot. The lower oven starts to warm up. If you set the lower oven, the exact opposite scenario exists.
Cause: When the upper oven is set, the control board turns on power to the elements and measures the temperature in the upper oven. The problem is that if the orange wire is connected to DLB2 instead of DLB1 and the yellow is connected to BA2 instead of BA1, the lower oven will begin to heat instead of the upper oven. In short, the wiring is wrong and needs to match the wiring diagram. Here is an example that covers most built-in GE ovens:
Upper Bake(BA1) - Yellow Lower Bake(BA2) - Yellow/White
Upper Broil(BR1) - Violet Lower Broil(BR2) - Violet/White
Upper DLB(DLB1) - Orange Lower DLB(DLB2) - Orange/White
This page ( fixyourboard.com/boards/WB27K5119 ) describes a common hook up problem that fortunately is easy to correct and causes no permanent damage. A partial list of model series that this applies to is: JKP44GT JKP44GV JKP45WP JKP45WT JKP45WV JKP54GP...

Hello, welcome to FixYa.
It sounds like the hi-limit safety thermostat may be tripped, I haven't seen anywhere in the post dialog where this has been mentioned or that you've checked it though, have you checked ?
I should also verify you have confirmed the lower element is getting 240vac and there is no wire breakage as that too can manifest in the manner you described.
As for the hi-limit safety, unfortunately it is the non-reset type hi-limit on these ovens, though it may sub to the reset-able type when a replacement is purchased ( if the oven is indeed a JKP45 model ) It is shown here and is behind the grill between the two ovens...
being that it is located between the two ovens behind the grill where the lock is for the lower oven, so it is a challenge to get to, but the part is available at "repairclinic.com" or "searspartsdirect.com" on-line parts vendor for approx. $10-20USD. but if you jump it out to test it and then replace it, you can get the oven back up and cooking.
** Please turn off the breaker before attempting any service please...safety first **
Let me know how you make out or if indeed you've already checked the hi-limit thermostat. I'll watch for your reply. Good luck.
