LAARS LIT2 Heater Problem

Model is LD400N, and it fires up for 2minutes after changing transformer which was blowing the fuse, but now it shuts off, I am told to change pressure switch, and rectifier rod, and the dual thermostat, but where do I start to save money? which one to change first, and where do I buy them on line?

My Laars LX pool heater would shut off soon after it fires up


This error is Automatic Gas Shutdown. Here is what you can do:

  1. Check for fluctuating pump pressure (air in strainer, pressure guage bounce)
  2. Check all wiring connections
  3. Replace ignitor/flame sensor assembly
Depending on your expertise, it could also be the gas valve or ignition control (aka the IID).

Since the burners do fire briefly, I would suspect the flame sense rod first. Attached is a link to the owners manual in PDF.

Lo Nox heaters can be a little tough so follow the directions exactly.
