SOURCE: Jandy 'Lite 2' 325 btu "LG" Natural gas unit will not fire up!!

You have to make sure the heater is wired for 110v where you hook the wires up to it. Depending on model it has a red and a black and a red tracer and a black tracer wireyour leads hock to two and the other two wire nut together It will have a tag or scematic to tell you how in a couple of places on the unit. If not that it will simpley be a plug that pulls out in one place and plugs in another. On the early units of that model it may be you just need to reverse polarity also. One more thing if it is a forced draft (with an internal fan) It is imperetive that you gas meter and gas line are sized correctly or it won't fire at all.

SOURCE: Jandy Lite2 Pool heater will not stay lit after firing.

Aside from the other suggestions made here... make sure you have the inlet, and outlet pipes from the heater routed properly. If you have them backwards, the unit will fire, then kick off shortly after.

Reason for this is because the unit kicks off when the water temp at the inlet reaches a specific temp, if they are swapped, it's measuring the water it just heated, not the water coming back from the pool/ spa. Make sense?

SOURCE: my jandy valve drips in the off position but stops

It sounds as if when the valve is in the "off" position it may be causing a build up of pressure on the valve. When the valve is "on" the water is nit restrictes and the bwck pressure is reduced to a point that allos thw valve to operate without leaking. the fix may be as simple as replacing the orings. Generally, a rebuild kit will cost $15.00 and can be installed by most homeowners. If that does not solve the problem, the valve may be worn out and need to be replaced. Over time, the holes that the screws around the top screw into just wear out to a point thqt they cannot be fully tightened.

Good luck and if you need to purchase a new valve, or would like to try a rebuild kit, call us at 602-74-3880.

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....

if you have not been keeping the water balanced, there may be a buildup in the pipes inside the heater core. this would cause the heater to work harder, produce less heat transfer and cause the over temperature sensor to kick out before meeting the set point.

My service light is on and I have a bO code. The heater will run some times, more time than not it will not run. Thanks Dave


The bO code is a normal code. It stands for bypass operation and just means that the heater is wired into an automatic controller such as a jandy or aqualogic. If there is a call for heat and the heater doesn't fire, you should be getting an error code. It may take several (3 or so) attempts at firing before you will get the code. HTH
