Dacor ECPS130 fan won't shut off

I have a Dacor ECPS130 oven installed in a kitchen island. Liquid was spilled down the front of the oven, the display went crazy and then the oven went into self-cleaning mode, the door locked an I couldn't stop it.  I shut off power to the oven and the door unlocked.  I removed the front panel and cleaned off the membrane panel and mopped up all the liquid.  After reinstalling the panel and restoring power the panel functions fine, all the controls react properly except that the fan runs continuously and I can't get it to stop.  I've tried hitting the high-limit reset switch with no luck.  I ran a resistance test across the switch and it is open. Any advice would be greatly appreciated or even directions to a schematic.
Thanks
