I have a Comfortzone (Hayward) 250K btu natural gas pool heater and I hoping someone can help me diagnose the problem.
It is electronic ignition and the spark is fine and lites the pilot quickly. The main burner then comes on strong for about 2-3 seconds but then shuts off. It will continue this cycle endlessly.
The pump is on, the thermostat is calling for heat, everything is as it should be and the heater has worked perfectly for the 6 years i've been here.
I replaced the flame sensor and the ignition control module with genuine Hayward parts with no change.
I would appreciate anyone ideas - I'm stumped and don't want to just throw more parts at it - the gas valve controller is $200 plus so I'm hoping there is another explanation. Thanks!
