SOURCE: heater will not heat

If you dont smell any gas make sure that all gas valves between the heater and the main gas meter are open, and the gas valve in the heater is in the on position. Try cleaning out the nozzles that the gas comes out of. Sometimes they can build up with cobwebs.

SOURCE: FL 4 error, Jandy Lite 2 pool heater

I believe you may have a draft restriction and this may stop the start up diagnostics. The draft detection switch is sometimes restricted or weak. Common problem. Tap the gas valve to see if the winter has caused the valve to seat heavily and stick.

SOURCE: I have a Jandy Lite

This sounds very much like spider webs in the gas orfaces. If you shut the power off and remove the wires to the gas valve then shut the gas down and remove the fed pipe from the gas valve you should be able to pull the burner tray out of the heater. Now if you remove the burners you should be able to remove the brass orfaces connected to the main gas feed pipe. If you use an air hose or a can of compressed air you can blow this out now. Now take the orfaces you removed and clean them with a tooth pick or a small piece of wire. The webs will look like small cotton balls or lint. They don't stop the gas they just slow it or disperse it and keep it from firing clean and evenly.
At this point you can reassemble the tray and install. This should fix your problem.

Display says "CFH" but heatert wont fire up. Just makes a clicking sound


You don't have gas supplied to the heater. It sounds like you have a gas powered unit and the clicking you're hearing is the sparker sparking.

We have a jandy Lite2, when turning on, you hear the igniter firing, and seconds later everything stops and the pool is not being heated!!


Does the heater fire up at all? If the igniter is ticking that means that it is trying to fire. The problem can be as simple as a clogged pilot orifice. Otherwise the gas valve may not be opening due to a bad wire telling it to open, or the gas valve has failed.


Also, double check that the gas cutoff valves at the gas meter and the one next to the heater are open, valve handle in line with pipe. Closed, the handle is perpendicular to the pipe. They have been known to shut themselves!

if it runs for the first 15 to 30 minutes and then no heat you have bad gas coils,located on top of the gas valve,when the coils heat up they fail,if you try to start it again after it sits for a long time it will lite again,also you could have a bad gas valve,try tapping the valve to see if it lites,if it does lite while you're tapping on it most likely it will be the valve,let me know what you find and send the model number.good luck

tough one doug, easy way is buy a new gas valve under red knob.
harder to try to fix old one.
the stopage of your mister heater is caused by the pilot lite going out
so what is causing the pilot lite to go out? that is the problem.

inspect the pilot lite and its gas supply tube all the way up to the main gas valve under the red knob control valve. unscrew the pilot lite gas supply line from the main gas control valve and clean out interior of gas supply line all the way through the pilot lite orfice to the open air. It must be totally clean, .like new, including the pilot
orface, in order to work properly.the least obstruction might deflect
or restrict the gas flow & cause poor or no opperation
.
when you unscrew the pilot lite gas supply line from the main gas valve,with a flashlight, look inside the hole, that the gas supply line was removed from.
It may be full of gunk that has to be removed for gas to flow properly. try blowing out with compressed air with a straw tipped blow gun. you may need carburator cleaner to loosen the gunk ,if gunk is present.
WARNING:::
If you use carb. cleaner, it burns like gasoline, so make sure any carb cleaner is blowed of with compressed air or blotted up with facial tissue & totally dried up & removed before firing up mr heater, in order not to catch mr. heater on fire.

If a lot of gunk is in the outlet of the main gas supply valve,you will
need a pocket screwdriver,a paper clip and maybe a sewing needle in order to pick out the crud.
It must be totally clean inside, like new, in order to have a chance at working.
It may still not work if more crud is inside the main gas control valve where you can not get to clean it out.

if you reach the point where you decide to buy a new main gas control valve, first try disassembling your old main gas control valve and cleaning it out,like rebuilding a carb, and reassembling it.
If this works,you dont need to buy a new main gas control valve
and have saved 30.00 plus 12.95 shipping
if it dont work,all it cost you was time & angervation.and you still need to buy a new main gas control valve.
