I have a issue with heater turning on when pump turns on and buttons on control board won't shut it off. I purchased a new control board and it still won't turn off. None of the buttons seem to work. Sta rite maxi therm 400.
Pump turns on in the morning on schedule but so does the heater. Can't turn it off cuz buttons won't work. Purchased new control board and same thing. Heater buttons won't work and heater turns on by itself and I can't turn it off. Buttons don't work. Had to take it apart and unplug all connections to turn it off. What's the problem?
