The easiest way to troubleshoot any heater, is to call the manufacturer. Their techs will walk you through each possible problem and solution until you find the answer.

the control module is the problem it allows the heater to come on then turns off power to the gas valve.if you are not getting enough water flow the high limit is turning the heater off then your problem is flow.

could very well be thermocouple or fan switch if you have a meter that reads millivolts you can check thermocouple output or fan switch for continuity if you jump out fan switch be careful cause you can go boom if you are not familiar with this type of equipement you should call someone who is

SOURCE: How do I access the thermocouple on my Laars Lite, LLD-400N

whoo told you it does the trick?The only trick I know that works on a thermocoupler is replacing it with a good one. It is the probe that sits in the pilot flame. If you take it out to scrub it, you may as well put a new one in its place . They are relatively inexpensive.

Teledyne laars series 2 pool heater pilot is on,gas is on,switch is on,pump is on,water flowing to pool,replaced thermocouple, and heater wont kick on. thermostat is set. what am i missing. Is there...


First of all, I'm assuming that your heater has a pilot and not self ignition.You will need a jumper wire ( 16" of wire with an alligator clip on each end)attach one end to the terminal on the gas valve that the red wire from the pilot generator is connected to ( pilot gen. is the thing the pilot flame touches).
Now attach the other end of the jumper to the terminal where the wire from the connects to the knob where you set the water temp).
NOTE:
JUMPING BYPASSES ALL BUILT IN SAFETY DEVICES AND IS FOR TEST LEAVE THE JUMPER CONNECTED TO RUN THE HEATER FOR HEATING PURPOSES!!!!

We have a teledyne gas furnace whose pilot won't stay lit. Any ideas?


Is this a standing pilot,or pilot always on.

If so a bad thermocouple will cause pilot to go out.

Thermocouple is a small copper tube running from the pilot light area to the gas valve. easy to replace.
