We had a power failure a day ago and now i cant seem to get my oven too fire. neither the broiler or the oven will fire. The cooktop works great. both igniters will turn bright orange but i cant seem to get any gas to flow. I have been able to get them to fire if i tap on the main valve or switch the main valve on and off. However if i jostle the range at all, by closing the door or moving back in place, the gas quits. i am thinking its a thermocoupling or something like the AP2138239 GAS SAFETY VALVE. any thoughts?

thanks,
JAKE
