Oven wouldn'theat, broiler didn't work, always going into sabbath mode

I removed the cover plates on the back of the range since I didn't know where the m1/m2 module was located. I traced the wiring back to the clock and timer module in the console. I ordered the replacement part and it came the next day by FedEx. I replaced the failed part and every thing works except the oven. I have to get a meter to find out if I have voltage at the oven gas valve or if the part 74009227 is faulty.
