I wonder if the relay and the heater went at the same time. Or if the faulty heater may have caused the relay failure. Or visa-versa.
The one post had rusted off the heater element plate. So before replacement I ran the heater with only one lead attached, figured it was probably 110v. It heated up OK, and other than being slow (probably 1/2 the heat) the timer and temp functions worked OK. So before the element was replaced, the panel/board was still working OK. Just when I switched it, the tried the new, the heat would not shut off. Coincidence? Can you ever tap on the relays to "unfreeze" or "unstick" them? Thanks for the comments. Skeetpick
