Blinking oven and heating Lights (by 2 users)

for no reason the cleaning light went on, even though the oven was not on. The oven light and heating light were alternating each blinking 5 times. The door locked up, too. It seemed to think it was in a cleaning cycle. Any way, problem solved by throwing off the main breaker and all is working fine since... except now, for no reason the oven fan, not the exhaust fan, stays on all the time!
