I have an amana oven mod#ACF4215AC that the self cleaning won't work. the door will not lock. "door lock" light flashes but won't lock, when I open the door and hold in the door "closed" sensing switch on the left side the light again flashes and will not latch. after about a minute of waiting for the latch to activate, there is a F9 error code that flashes. Everything else on the oven seems to work without issues.
