Question about Jandy Laars Lt 400,000 Btu Heater
My Jandy LT 400,000 doesn't come on. When I turn it on the blower doesn't come on and in a minute or two the service and high pressure light comes on. What could the problem be and what do I do?
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?!?

Re program your assorted timer functions and make sure you set AM and PM or use a 24 hour clock. I think your model allows for a 24 hour clock setting but I am not certain.
I hope this helps you

I had this problem. Jandy ended up replacing the burner from day 1 with the heater (LT400 propane). It was a manufacturing defect. Of course it took 5 trips from the "warranty" company to not fix it before they finally punted to Jandy. Then, there's only one Jandy service rep from VA to ME (I'm in PA).
