Pool Heater Troubleshooting Help (We have Laars Lite 2)

[PoolGuy01]

Our Laars Lite 2 heater won't fire up. The Pilot light is lit; but turning it on does not light the burners.
Is there an easy method to troubleshoot?

- Would like to determine if the on/off switch is working. Is there an easy way to do that?
- If switch is working, is there anything I can easily check?


Thank you,
Steve

Find the manual on the Internet.

Use a multimeter to check continuity and voltages expected.

Probably one of the safety switches open.

Thanks Allen. Is there anywhere I can see a video of what the pilot light should look like when properly lit? I read somewhere that if its dirty it might not be hot enough to trigger other events.

NG flames should be blue with maybe yellow tips. Not yellow or orange that indicate a poor air/fuel mixture.

Think about it. If a pilot flame is hot enough to be igniting it's gas feed then it should be able to ignite the gas in the burners.

Let's see what @swamprat69 says.

I think that this may be the manual for your heater https://shop.solardirect.com/pdf/pool-heaters/gas-pool-heaters/jandy-lite2manual.pdf Since you have a pilot, I am assuming that you have a millivolt heater with no electrical connection for power to the heater. How old is the heater? Has the heater ever been cleaned or serviced? Pilot flame shoud be a couple shades of blue ( inner and outer cones ) and possible brief yellow/orange flares at the edge of the outer cone from entrained dust/debris burning off. Do you have a multimeter and basic knowledge in its use? Photos of heater label, front controls and wiring would be helpful.
