SOURCE: Model LG Lite 2 pilot is lit but the burners will not light

If this is a standing pilot you will want to check your voltage out put from the pilot. For this you will need a milivolt meter. The pilot should supply 500-700mv (1/2-3/4v) It only takes 200mv to open the pilot valve but needs another 300+ to open the main half of the gas valve. This would be the first thing I would check. If this is the problem you will need to replace the pilot assembly. If your getting the power you need from the pilot then it is probally your gas valve itself. Good luck.

SOURCE: I have a Jandy LITE2 LG325. Only two years old.

Does the pilot light stay light? Or light then go back out? If it is doing that then it is the thermocoupler. looks like a wire that is in the flame of the pilot light. Other than the sparker. That is what dectects that there is fire in the pilot light before it starts the gas. Safety thing. So if that isnt detecting fire, then it will never let the gasvalve open up, Try taking some steel wool or real fine sandpaper and clean up that sensor. The wire. It builds up a thin film on it from gas burning.

Ignites but wont stay lit


I started getting the FL2 ignition failure error code on my Jandy Lite2 Spa heater again this week. I seem to get some variation of this problem every few years, by which point I've forgotten some of the details like which screws not to take out.

So, in hopes of saving someone else, and possibly myself, some
time in diagnosing this, here are some notes and pictures re
how I fixed it.

One time it was a bad ignitor. That's the part w/ 2 white wires sticking out just above the burners in the first shot. It's easy
to order online and replace.

The harder problem which I've seen most often is when the burner lights, but shuts off after about 5 seconds because the flame sensor doesn't detect the flame. The flame sensor is the glowing red rod to the right of the flames in the first picture. I took this shot after
cleaning it and getting the heater working again.

The second picture shows where it's mounted below the burner w/ one black wire leading to it. Don't remove the screw on the flame mount as the nut behind it comes off and is a bear to get back on. Besides, there's another screw that's nearly impossible to get to that keeps you from removing the sensor w/o removing the burner assembly.

However, I've found I can reach up from below w/ some steel wool and clean the corrosion off the flame sensor rod and that has fixed it
at least 3 times as I recall.

You should also check the burner tubes to see if they've been blocked by spiders. That happened to me once on a gas grill. Be sure to keep your face back when testing w/ the door off so you don't get singed.

Hope this helps!

I have Laars Lite2 125k BTU Propane. pilot stay lit and after some time hear click sound in gas valve but it will not fired up and also pilot goes off right away.


It sounds like you need to replace the pilot generator. This is the metal cylinder that sets in the flame of the pilot and supplies voltage to the system. When it gets weak, it will support the pilot valve to remain open, but when the main valve tries to open the pilot generator cannot provide enough electricity, and everything shuts down. It's a prime suspect in your situation.

Why won't the pilot light stay lit?


You have a "pilot generator" that sits in the flame of the pilot light. This generates a low voltage output from the flame of the pilot light. This voltage goes to the gas valve and tells the valve that the pilot is lit and to keep the pilot gas line open.
In almost all cases replacing the pilot generator will resolve the issue . They run about $60-$75.
Other causes may be the gas valve itself or a short in the safety loop, in either case should be looked at by a pool tech.

Jandy lite 2 pool heater will not stay lit.


I'm having the same issue as the above user with Jandy Lite 2 (which from what I can tell stands for the number of times that you can get this POS to work annually)!
The unit LIGHTS OFF, but WON'T STAY LIT! Igniter engages, gas valve opens, unit lights, burns for 10 seconds, and flames out. Error code FL 2, after third attempt, already replaced the flame sensor....

What is the flame sensor


The flame sensor is attached to the pilot light. It's down on the right side of the burner tray and usually has an orange wire attached.
The flame sensor lets the heater know that the pilot light has been lit and it's okay to open the main valve.

Jandy LG250N pilot won't stay on after releasing switch on gas valve. Main switch on unit is off. I am able to keep pilot flame on for one minute by depressing switch but pilot always goes out after...



Thank you for posting your question here on Fixya.com.



No, the pilot generator or the pilot head itself is the issue. You need a good, solid blue flame across the generator to get enough power to hold the switch open when you let go of the knob. If the pilot flame is week or not aimed across the generator it will not stay lit.



If it is but the generator is old and weak, it will go out as well. If you can see the pilot flame and it is a nice blue color, replace the generator. If it is not, disassemble the pilot and either clean it out or replace it.

How to I start my heater


If it is this heater, then you must:

1- turn the toggle switch to the ON position.
2- Turn the gas valve dial to the PILOT position.
3- Depress the pilot button while pressing the ignitor until you see a flame. Continue to depress the pilot dial for about 30-60 seconds.
4- let go of the button, and the pilot flame should stay lit. If it does , then turn the gas valve dial to the ON position.
5- Set the temperature and your done.
