Question about Jandy Laars LX Pool Heater / 400,000 BTU / Natural Gas
This is most likly your heat exchanger and you will probally need a new one. It will be expensive and you will probally have issues with some other components. This is almost always caused by chemical damage. If your heater is very old it is probally time for a new heater.
Sorry for the bad news.

I have two LT/LX units - one I use and one I keep just for parts. In taking them apart, I can see in the header gaskets where the water escaped out on both of mine. Looks like the gasket is designed too thin. You may very well need a new heat exchanger, (very costly) but you might try a $20 gasket replacement first. Part number is R327500 and fits the front or rear header. $25 bucks for each header with shipping from a variety of places on the internet.
