Woke up to timer alarm going off--it was not on or set. Could not get it to stop. Cut power to range and turned it back on via circuit breaker. Alarm/noise stopped but ERC/clock dead. No function for any of the oven buttons, clock, etc. I assume the board is dead but need to know if there is anything else that could cause this before I order a new ERC. I still have power to the range. Top gas burners ignite automatically and oven light goes on and off with switch.
