We have a GE double oven Model- JTP280F4SS, serial No. HH6054140 and the lights turn on when we open the doors, however, we can not turn the lights on with the doors close using the panel switch.
Please indicate what part we need to replace.
You will want to check the keypad to make sure that it is working for the oven light. You can do a continuity test on the keypad from pins 9 to 13 on the keypad ribbon. When you push the oven light button there should be continuity. If there is not then the keypad is faulty. If there is then the control board is faulty.
