the display does not show any flow of water and the display does not show anything but there is water going thru the heater could this be the problem

Hi Vince it is possible that this could be the issue as this is one of the most common parts in pool heaters to go bad. It may also be the case that your flow through the heater is lower than 2 PSI as this is the pressure required to activate the switch.

The code FL4 comes on and will go away after turning pump on and off or by just letting the heater cycle 2 or 3 times. Heater will go into display mode and display FL4 if after 3 times it does not cycle on. I can repeat steps above and it may come on line, it may not. Could this be the pressure/flow switch.
Thank you
Peter

Hi Peter, The "FL4" error code in the Lite 2 LJ Troubleshooting Guide refers to a bad Igniter (R0367100).

I need to replace our pressure switch,on our LD250N. how do I select the correct one,with the correct PSI setting?

There should be a model number on a sticker on the pressure switch that you are looking to replace. I would verify this information against the alternate part numbers listed for that switch for confirmation.

I have a Laars Lite 2, Model LD125N, natural gas pool heater. The pressure switch is leaking water. We need to replace it. What is the correct pressure switch we need to purchase to replace the bad one? Also, does your recommendation for a replacement come with all the necessary compression fittings to install it? Thank you.

You need the R0013200 to replace what you have. It doesn't come with the compression fitting as this is on the siphon tube

47-295-1027 will work as a replacement pressure switch & does include the compression fitting.
