Question about Jandy Laars LX Pool Heater / 400,000 BTU / Natural Gas
I have a Jandy LX pool heater, and Im getting a low pressure reading which is prevent the heater from starting. Water flow is fine and fiter is clean. Do I need to replace the pressure switch?
I had this problem with ours last year. I replaced the water pressure switch and it began working fine. We later had a symptom that the blower would start but it would not ignite. The ignitor rod was corroded so I took it out and sanded it with some sandpaper---worked fine...until I dropped it trying to reinstall and it broke. Bought a new one and it works fine now.
Today's problem is related to the blower now.... it is always something, isn't it?!?

I have the exact same problem. Just opened the pool and heater won't start due to low pressure flashing on screen. Does anyone know what is causing this and how to fix it?
