Check for bad signal using Service Mode.

• 

Remove the ribbon cable from the upper  

• 

door and measure resistance:

Upper = Pins 13/14; Lower = Pins 11/12

• 

If resistance is high, replace the oven sensor.

•

• 

harness terminals or replace the display/
logic board.

F3

Open oven sensor (over 2850 ohms)

Check for bad signal using Service Mode.

• 

Remove the ribbon cable from the upper

F4

Shorted oven sensor (under 950 ohms)

Check for bad signal using Service Mode.

• 

Remove the ribbon cable from the upper 

•

If resistance is okay, look for damaged 

• 

harness terminals or replace the display/
logic board.

F5
