Question about Jandy Laars Lite2 Ld 400,000 Btu Heater

1 Answer

Jandy lite2 heater has fl5 error code, all voltages look good

All test points have acceptable voltage except will not energize igniter. Power control board is expensivr to replace on a guess.

If all voltage test points are within range, then it's 1 of 3 problems: Power Conversion Plug is faulty; Power Control Board is faulty; or Controller is faulty. Jandy says there is no way to test any of these directly. They recommend that you replace both the Power Conversion Plug (~$35) and the Power Control Board (~$230). Apparently when one fails, it can cause the other to fail as well. They said that unless the Controller has a lot of corrosion on it, then it probably is not the issue.

Error code hf hayward model h200ped2 after replacing control module


HF is a flame sense failure. make sure the off\on switch is in the on position (on gas valve in heater) if you are using an automation system, you should see BO when the pool is running and heat is not called for. if this is the case, you need to take the heater off of remote control and try to manually call for heat using the buttons on the heater. if it fires, that would make me think that there is a compatability issue between the new board on heater and old board on automation.

I have a Jandy LXi 400N that will not start. I push the button and it wants to go, but the blower does not come on. Sometimes the blower comes on and it works and other times it tries to come on, but...


The blower must be operating during the test procedure
for the blower pressure switch. Start by checking the
voltage between test point 1 and the common and
normally open contacts of the air flow switch.
Leaving the black lead of the meter on test point 1, check
the voltage at test point 11. If there is not 20-28 Volts
AC at this point, the eight-pin wire harness is faulty and
must be replaced. If 20-28 Volts AC is detected at this
point, then move the red lead of the meter to the Air Flow
Switch NO contact.
If 20-28 Volts AC is detected at this point, the device in
this circuit is closed and the circuit is working properly.
If there is not 20-28 Volts AC at the Air Flow Switch
NO contact, the pressure switch contacts are open. This
is usually due to a blower speed problem or a problem
with the air pressure tube connection between the blower
housing and the switch.
Be sure that the blower is on and that it is working
properly. Check that the gray flexible tube between
the blower pressure switch and the blower housing
is connected at both ends and has no holes or splits.
Replace the tube if necessary. If there is no problem with
the blower or the tube, check for blockages in the vent,
flue or heat exchanger that would prevent air flow. If no
blockages are found, replace the pressure switch.
If the Air Flow Switch NO contact shows 20-28 Volts AC
and the ignition control shows an air flow fault, then there
is a bad connection between the blower pressure switch
and the ignition control, or the ignition control is faulty.

Hurlcon spa heater won't ignite


I have a hurlcon mini max 120 spa heater Same type of problem. If you can't hear the relay click when you turn it on......your control board is faulty even if all the lights on ie power, flow, heat... The power for the igniter and gas valve is the orange wire coming out of the control board. if you test this with a test light (24volt) it should light up if not check power coming in. if it has power replace control board or get some guru to fix it. hope this helps

Flashing service code, indicates brownout, checked electricity to computer, 240volts, what next?


A brownout can be detected by checking the dc voltage being supplied to the electronics in the main controller board. If anything upstream of this point is causing a lower than normal voltage from getting to the controller board. The condition is checked with a comparator circuit, comparing this voltage to a reference voltage. Here are some possible causes:
1. Lower than normal input voltage (brownout).
2. Bad connection in the power wiring.
2. Defective voltage reducing transformer.
3. Faulty rectifying and filtering circuitry.
4. Defective comparator or reference voltage circuit.
5. Defective micro-controller reading the under voltage signal.

What I would do if one of my customers had this issue is prepare to take voltage measurements on the heater by being able to open it up and having a volt/ohm meter available. I would then call the Haywardtechnical support at 908-355-7995 and see if they can lead me into measuring the dc voltage on the board that has the comparator circuit and the ac voltage being supplied to this board.

If the voltage is low it needs to be corrected, maybe by replacing the transformer or repairing a bad connection. If the voltages are normal then I would suggest that it is a false alarm. If the heater still works then I would discuss with the customer that the heater was getting a false alarm but continued to heat. The customer could then decide weather they wanted to replace the board to correct the alarm or tolerate the false alarm.

Please fill me in on what happens and ask any further questions. Thank you.

Does this heater need to run on 220


Electrical connections :

The heater is shipped from the factory wired for use with 240VAC, 60 Hz field power supply. To convert the

heater to 120VAC, 60 Hz operation remove the 240VAC voltage selector jumper from the ignition control board

and replace it with the 120VAC jumper. These jumpers are tie-wrapped together and are located on the fuse
board.

Pool heater gas fire lights up and turns off 10 secs later


Assuming you don't hear any banging noises, that cycle is by design. There is a fault. 2 possible causes are the ignition board is bad, or the ignition sensor is not returning a voltage indicating the flame is lit. Take this out and put the ignition piece on your stove flame. Check for voltage while on flame (DC millivolt setting on multimeter). Put one probe on ground other on sensor lead. If it doesnt have voltage this is bad. If you do, its possible your board is bad.

it should be the other way around actually.The gas valve should remain closed until the board gets a signal the the pilot light is lit or the board has heated up the hot ignition surface.which ever you have .I imagine hot surface ignition outside.is the hot ignition surface glowing.if not if may be cracked check for a crack,or a loose connection.if the hot ignition is glowing you should also be getting a signal to your thermostat.remove the wire,and check for a voltage.if you have a voltage,the problem is with your valve.check to make sure your gas is turned on as well.If it is a pilot lite make sure your thermocouple is making contact with the flame.
