Question about Jandy Laars Lt 400,000 Btu Heater

1 Answer

I have a Jandy LT low NOx heater, about 3 years old. It worked once this season, but now I turn it on, power light lights up, but nothing happens (no air/gas, etc.). Gas lines are on and water is flowing thru.

I have a Jandy LITE2 LG325. Only two years old.


Does the pilot light stay light? Or light then go back out? If it is doing that then it is the thermocoupler. looks like a wire that is in the flame of the pilot light. Other than the sparker. That is what dectects that there is fire in the pilot light before it starts the gas. Safety thing. So if that isnt detecting fire, then it will never let the gasvalve open up, Try taking some steel wool or real fine sandpaper and clean up that sensor. The wire. It builds up a thin film on it from gas burning.

Service light and ags light comes on after a minute or two


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).

Laars Lt heater will not start- pressure switch light


it is time to check your filter make sure is not dirty and if your filter is clean and still doing this then the problem can be with one of the safety sensors they do have 2 hight limit switch located in the heater heather they re round with two wires on each one turn power off to heater and get a voltemer reader and check the hight limits for continuty they should read zero on your metter it can be your temp sensor heaters are so complicated that it is always good to have a pool tech service it I was a pool tech in california but now I am located in georgia
