After verifying that the heat element was good, (about 20-25 ohms of resistance),and that the temperature probe had approximately the correct resistance for the ambient temperature, the only thing left was the control board, or a component on it. oh, checked for voltage on each side of element and voltage on one side was missing. Local parts supplier said no returns on electrical parts, so i was concerned in case it was not the control board after all, but it was.
