Intermittent Oven Keypad Membrane Connection

• We see this problem frequently. It sometimes causes intermittent operation or an error code to be displayed.  

MODEL

• • Many different models of ovens

SYMPTOMS

• • Intermittent operation of oven buttons, sometimes results in a keypad related error code.

Typical membrane connection. This one is a Whirlpool/Kitchenaid model.

PROCEDURE

• • Carefully release the locking tabs on the zero-insertion-force connector that holds the keypad ribbon.

  • Pull lightly on the locking tabs in the direction away from the pcb.

• • Next check for oxidized contacts on the membrane tail.

  • These contacts on the membrane are oxidized and cause poor electrical connection to the control board.
