I have a Sta-rite pool heater that will not ignite. It has a fenwal ignition module with a red light that blinks 3 times when we try to start the heater. Manual says if the light blinks 3 times it indicates an "ignition lockout". All other led indicators (AGS, AFS, SFS, HLS, PS and THERMISTOR) are off. Gas is on and you can smell it for a few seconds as it trys to ignite, but then the fenwal light blinks 3 times. I tried resetting the breaker switch and still get the same result. I have the temp on the pad set to 95. Water temp is about 75. Heater unit is about 5 years old.
