I have a 10 month old new Laars pool heater.
Just fired up for summer (off during winter).
Pilot lights, boiler kicks in...then after 5mins everything turns off.
Then have to do it all again!
Thermostat is set properly, just don't know why it all shuts itself down?
-   Have the same problem - heater works well, intermittently. Checked (methodically) the following:
pressure switch
fusible link
fireman's switch
on\off switch
hi-temp limit
potentiometer (thermostat)
and thought I'd discovered a problem with the on/off switch. Bypassed to no avail - still performing intermittently. Very frustrating. Would recommend anything but Laars!

I am winterizing my Laars Lite2 pool heater and have what may seem to be easy questions but... What Do I grease the drain plugs with before I put them back after draining heater?. Should it be Silicone based? Also where do I blow the compressed air to dry out heat exchanger?.. Thru the drain plug holes? Thanks

I have a Laars LX400 heater. Yesterday the heater would not start - Hi Lim SW error. I replaced both of the limit switches. Now when I start the heater, there is no sound for a minute or so and then I get "Air Flo SW" error.
