Laars LT400 heater problem-won't light

Postby fireman1173005 » Mon 30 Mar, 2009 17:48

I have a Laars LT400 propane pool heater. I can't get it to ingnite and keep getting an AGS (Auto Gas Shutdown) sensor flashing light. It will try to ignite several times but will not. The wires were broken to the Hot Surface Ignitor so I replaced it. I took the burner tray back out and plugged the ignitor back in and cycled the unit with the propane off and the ignitor did not get hot, should it with the propane off. Is there any way I could check it with the burner try installed?
