That involves changing out the complete burner tray including the igniter/pilot assembly, burners and the gas valve. It runs deep into the cost of a new heater, (well over $1000, not installed).

Laars-lite LD 97-2000 pool heater wont burn


cycling usually begins as the result of poor water flow caised by debris in the pump, dirty filter or low water level. once you have had some cycling the heater burners and ignitor become sooted and this requires pulling the burner tray, de-sooting the burners and pilot and reassembly. unless you are very competent you may want to call a service tech. Pool heater repair is a high laibility endeavor if done improperly. During the certification class our instructor showed us several houses that were burned down from improper heater repair.

Laars lite 2 pool heater burner not lite


If the pilot flame is not strong enough, it will not tell the gas valve to open, or if the gas valve is not getting the signal to open, it won't. Check all wire connections at the thermostat and gas valve. Check ground wires. Clean the pilot light and flame rod.
