I have a Jandy LX 250, about 8 years old. It is connected throught the fireman's switch to a Jandy RS6 control center. Both thermostats (pool & Spa) on the heater are set to max. The heater will come on and bring the water up to the temperature set on the control center. When the water temperature drops, the control center activates, however the heater doesn't come one. I hear the blower fan for maybe a minute. then nothing. No error lights, and the spa or heater light remain solid. Rather than start blinking when the burns are light. I hear no ignition clicks.
It seems after it sits for a while, the heater will come on, and the process will start all over again. I have replaced the temperature sensor, and cleaned the flame sensor.
Any thought on what the problem may be?
Thanks,
