Customer Question

I have a hayward H400 gas heater. It was worked every year. I just opened my pool and all is fine. the heater display will changes MODES and the water temp is displayed but the temp will not change up or down. Obviously the heater will not turn on so I dont know if it is the board itself or another issue
