Jenn Air Ventilation/Downdraft not turning on

My ventilation fan/downdraft fan will not turn on but the rest of the stove works. I had the fan on yesterday and we had a very brief power failure and now I cannot get the fan to turn back on or the oven to warm up. Could the PF have triggered something? Is there any sort of reset button for the fan/blower? Any help would be greatly appreciated.
