Hello!
I have a Pentair Mastertemp 250 LP Gas heater. It has been working since about 2009. Lately it was having issues where the membrane buttons do not work. I replaced the membrane and it has been fine. This week, the heater will not turn on. I turn the power off at the breaker and then back on. The LCD will go through the boot up process and get to C4 and then turn off. Any Ideas?
