Question about Jandy Teledyne Laars HiE2 Pool Heater 350000 BTU Natural Gas

1 Answer

During a recent power outage my Jandy Pool Heater Hi-E2 no longer would initiate the heater. I tried the standard process or turning off and then turning back the heater - which I've done on numerous other occasions during the 10 year life of my heater. Any recommendations before I call my gas or pool repair company to come out?

SOURCE: jandy aqua link main control box

Do you have a 4 button switch in the spa and is the light on the button that is slightly under water? If so , the button is bad as the water is completing the circuit and turning the light on and off.

Repalce the button or disconnect it at the outdoor panel.

SOURCE: low pressure reading on Pool Heater

I had this problem with ours last year. I replaced the water pressure switch and it began working fine. We later had a symptom that the blower would start but it would not ignite. The ignitor rod was corroded so I took it out and sanded it with some sandpaper---worked fine...until I dropped it trying to reinstall and it broke. Bought a new one and it works fine now.

Today's problem is related to the blower now.... it is always something, isn't it?!?

The air flow switch is in the upper panel on the inside of the heater. There are gray hoses plugged into it.

SOURCE: I have Jandy RS4 system with 4-button poolside

Pull the cover off the control panel. You will probably find a button which would be accessible from outside the panel with a paper clip or pencil but is unlabeled. On the board itself by the button, in small letters it should say "reset". Push the button and see what happens.

If the unit is lighting then shutting off then repeating it isn't rectifying, means not sensing the flame. May have a bad flame sensor or ignition control. I'm guessing your AGS is indicated on the GUI also.

My Jandy Laars Natural Gas pool heater (LJ250N)

Check your heater by-pass valve and be sure it is almost closed. If not that then it will be your internal by-pass. These will force water through heater and keep it from overheating the water inside it and shuting it down. Also check to be sure the baskets are clean and the filter is clean.

Laars HI EZR heater does not come on

Hi. I work on Laars HI-E2 heaters at the hotels and there are 3 possible problem. The igniter, ignition control module or "not enough air for good hot combustion" are the main sources. I can go into details about my experiences. I suggest it is best to contact a service company to look at the problem.
