My oven and stove works fine, except the off key for the oven does not work anymore.
Answer Hello George. Based on the information you provided, it sounds like the membrane is bad and will need to be replaced on the unit. The membrane has been permanently discontinued by the manufacturer and we don't know of any source or replacement for the part.
I understand that the Whirlpool number AP2929485 is for a black control panel. What is the number for the white version?
Answer Andrew, the white control panel assembly listed for your model is part number 4451289. Unfortunately, the control panel assembly has been discontinued with no further replacements or cross references available and our company is unaware of any other available sources. Sorry about that!
