Wall Oven F5 Error HELP

I have a Kitchen Aid KEBI200YBL0. I have a F5 error on the upper oven. When I turn on the oven in the "CLEAN’ mode, I get a "DOOR" message then F5. The lower oven works fine.

I have checked the switch on the oven cleaning latch and in seems be be OK. One side of the switch is normally open and the other side is normally closed. When the latch is engaged, the terminals open or close opposite their normal position. Can anyone provide any guidance?

Thank you!
