Jenn Air Oven Dispalying Error Code F7

Please make sure to click on General above and select the correct appliance type first.

Brand: Jenn Air (Maytag) Oven
Model Number:ww27430P
Main Symptom:Display showing F7
What happens & when: I have a in wall double oven - one display panel - Oven started beeping displaying F7 on temp display.

Clock still works but none of the buttons will respond -

Manual says F7 is either the membrane or the control board.

You have the control board available (according to your website) but not the membrane (not available anymore)

How can I determine which one it is before I order a board.

Any testing?

Error Code (if any):

You can test the membrane switch connections using the chart below and a multimeter set for continuity. I’d start by using the Upper Cancel button to determine which end is # 1 since they don’t have a better reference to go by other than that. Press on the button or pad in question to make the circuit you’re trying to read for continuity.
