    Laars lite 2 model lg 250 000 btu. The pilot light is on and putting .495 milivolts to gas valve. Pressure switch is closed and all components ring out. The light on the square black module is not flashing. Any ides?

    No red led light as well. Jumpered around everything and still no ignition. How much milivolts do you need for the system to work? Could it be the pilot generator? Help!!

1st time this happened to me the filter wasn't clean. 2nd time it was the pressure switch and for the third time they say I have to bleed the gas line, not enough gas to lite. And I also need the on/off switch gone bad.

Hi I am unable to get the pilot light to stay lit even though I have replaced the thermocouple on my laars lite 2 heater ?. I checked te voltage on the pilot geneator and it rose from 300 mv to 600 mv but...


I take it you are talking about the powerphile which will give the readings you have , check pilot is not blocked , do the leads from the powerphile go on to the valve with out any other conections in the wire as this will drop the volts and it will not work , check thermocouple is tight and is in the flame from the pilot ,

Pilot lights but main burner dose not light when turned on


possibly a fowled thermocouple if the thermocouple doesn's sense the pilot flame then it will not send a signal to the gas valve telling it that its okay to open cause the pilot is lit.

Pilot light does light , but as soon as you release the gas knob it goes out


Hi there. You must continue to hold the knob in for at least 30 seconds before releasing. If the pilot still goes out, the "thermocouple" is bad. It's the little tube in the pilot flame. To replace, remove the main burner assembly/pilot. You can get a thermocouple at any hardware store. Ask questions while you are there.
Thanks

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 Pilot will not light


If you have not found the problem yeat, it IS the thermocoupling( or pilot generator(same thing))
You may test by placing a multimeter on the red and white leads coming to the gas valve. you do not need to disconnect the leads first but you can
