My Frigidaire electric range is starting to act possessed this Halloween season. I hear the controller act like it is turning on the stove top elements. I am not sure if they come on or not because it seems to pulse very quick. The cook top cooling fan starts and the hot element indicators come on for 3 of the 4 burners. The knobs are in the off position. Nothing has spilled onto the controls to suggest this may be a random short.

Any good way to isolate this to the control module or the relay board? Before I spend $$$$ on ordering all new parts I'd like to isolate this to the particular module.
