Report "I have a stayrite pool heater and i just replaced the control board and the membrane board # is 42002-0007s I also checked to make sure that I have a flue sensor and not a switch. I programed the board to SF1 as the instructions said to do so. Everything turns on but the temp. read out on the board is saying that the temp is at 105 F and it is not that hot. Also there is a lot of clicking taking place on the back of the board but nothing is happening"
