Question about Teledyne Laars Laars Lite 2 Pool Heater 125,000 Btu / Propane Gas

1 Answer

Every year I have a problem getting it to light. The pilot is lit but the heater will not turn on. It is 8 years old and I have been having trouble with it since day one. My pool guy comes out fires it up and charges me plenty but this year it worked on day of opening but hasn't worked since.I don't want to pay for another service call.

First, check the gas valve and make sure the valve in all the way to "on" not "pilot".After shutting to off for the winter, and not turning the valve all the way on start up could be it. If that is ok, check/replace the pilot generator next to the pilot lite. One question. Does the pilot go out soon after calling for heat? Next, if you have it on "spa" or "pool" on the temperature adjusting module, try the other setting. eg. If it is on "pool", switch the knob to "spa" and adjust the temperature.

SOURCE: Pilot light is lit, but heater will not fire

Make sure thermostat is set higher than water temperature. Make sure pump is running and water is flowing through unit. If gas valve is not opening then flame sensor or gas valve is bad.

I have an Americdan Water Heater 50 gal. gas. 38000BTU the pilot light does not stay lit. what can i do?


Usual problems are:. Bad thermocouple, Bad vent, blowing pilot outl. Too small of pilot flame. Low gas pressure Leaking water heater, dripping on pilot. Bad gas valve. If your water heater is more than 8 years old and the gas valve is bad, I would replace the water heater. IF you decide to replace the pilot or the gas vavle, be sure to mount pilot exactly as is was designed. If you replace gas valve get an exact replacment or a "listed" replacement. If you'rd doing this and it's older, replace the temperature/relief vavle also. Water heaters can be very dangeroius if not properly repaired/maintained.

I have a Raypac C155A LP spa heater. won't light


I would agree with you. The pilot generator has probably degraded over the years and is only proving enough millivolts to power the pilot but not enough to run the gas valve for your main burners.

Replacing the pilot generator, preferably the entire pilot assembly, will fix the problem.

My 1.5 yr old gas water heater has a pilot light problem


YOUR WATER HEATER HAS WHAT IS CALLED A STANDING PILOT-STAYS LIT ALWAYS WHEN THE PILOT GOES OUT YOU LOOSE EVERYTHING. YOU HAVE TO REPLACE THE THERMOCOUPLE WHICH KEEP THE PILOT LIT. ONCE THE PILOT IS LIT THE THERMOCOUPLE SENDS IN MILLIVOLTS TO THE BURNER TO SAY ITS READY FOR BURNING

GWN10T pilot blows itself out


You must clean the pilot regularly to ensure it burns properly. Use a small can of air for cleaning computers and blow air through the pilot to remove dust and small particles that accumulate in the pilot barrel. Use several burst being that it is 2 years old and has not been blown out. THe manual references cleaning the pilot in the maintenance section.
