Paul K. for Model Number KHHC2090SSS0 My KitchenAid Convection Microwave hood has been a problem child over the years. Phantom key strokes and beeping over the years. Keypad now freezes and can't use with Error code F2.Q1. I have to cycle the power, sometimes many times because code F9. Q often displays when I plug it back in. Please advise which part is to be replaced Touchpad wpw100116267 or Circuit board WPW10391280 since they both have the same generic description. Trying to limp along until Kitchen remodel late 2018 or 2019, But the $$ are adding up. Also on an unrelated topic, I recently purchases a new turntable motor from you. I repaired it and it works well now, thank you. However, immediately after the repair, my exhaust fan stopped working properly. It will only blow at a very low speed. Lights still work fine. I traded one problem for another, Suggested problem? Worth fixing?
