Question about Lite On Laars Lite 2 Heaters: 250,000BTU MV Heater

1 Answer

Laars Lite 2 - Turns off after 5mins of being on!

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!



    Would appreciate any help....

Pool Heater Light main burner then goes out


take millivolt reads while main burner is on.i suspect you will see a drop in voltage until you get to point where it will no longer operate burner(around 200mv).if this is the case you probably have poor pilot characteristics due to dirty pilot,pilot out of adjustment ,obstruction or insufficient gas pressure

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.

Won't fire


It may also be the high temp switches under the 2" inlet/outlet header. The 150 degree high-limit switch sits horizontal and corrosion happens often there. But be careful removing as if the header is corroded and the switch is also, water will flow out , so be ready to bypass the heater. You will have to replace the header. Try to jumpe that switch out and I'll bet the heater fires up.
