We used the broiler in our oven last night and it wouldnt turn off so we had to unplug it, By unplugging it, the igniter goes out, the temp. falls and the gas valve shuts off the gas flow.
So this morning I plugged the oven in to check it and the igniter/glow plug came on reached the neccessary temp and the burner ignited, the control knob does nothing to contol the level of the burner and it definetly doesnt turn off like it is suppose to. Im thinking the control knob is stuck open. How do i re-place the contoller? Thanks
