Jenn-Air single,combo and double wall ovens,drop-in and slide-in ranges. Prior to 1997. Models ( D156, S176, W276, W256, W156, WW2780, WM2780, W2780. )
F0   Shorted key failure ( check keypad for a stuck keypad )
F1   Failure in element relay circuit ( press cancel key. If alarm persists,isolate the touch pad from the clock. If failure returns issue is the clock. If failure does not return, issue is with touch pad.
F2   Temperature runaway ( Ohm sensor and check wiring. Verify oven will complete a clean cycle without failure. )
F3   Shorted sensor ( Ohm sensor,sensor wires and inspect sensor for damage.)
F4   Open oven sensor ( Ohm sensor,sensor wires and inspect sensor for damage.)
F6   EEPROM failure ( Replace control )
F7   Clean circuit ( Check door switches and the wiring to the switches )
F8   Door switches ( Check door switches and the wiring to the switches )

F1-3  Oven temp above 950f in a clean cycle. ( ohm sensor and harness. If ok replace control.)
F1-5  Cancel key not responding. ( Ensure ribbon connection,inspect for corrosion. Should normally read open and 1k-3k with switch activated. If ok,replace control.)
F1-7  Membrane disconnected. ( Ensure ribbon connection,inspect connection for corrosion,etc. Should normally read open and 1k-3k with switch activated. If ok replace control.)
F1-8   Shorted key in membrane switch. ( Ensure ribbon connection,inspect connection for corrosion,etc. Should normally read open and 1k-3k with switch activated. If ok replace control.)
F1-9   Internal communication with the control. (replace control)
F1-A   Control does not see state of lock or unlock switches. ( Check connections at the door lock assembly to control and check lock mechanism wiring harness. )
