Jandy LX/LT Hot Surface Ignitor for Low NOx Heater In stock$12599
Quick overview
- Genuine Jandy Factory part R0386900, the ignitor specified for these heaters.
- Low NOx models Built for the Low NOx version of the LX and LT heaters, which is a different ignitor from the standard LX/LT part.
- Hot surface ignition The element heats until it glows and lights the gas directly, so there is no standing pilot to relight.
- First suspect on a no light fault A heater that calls for heat, runs its blower and then locks out often has a failed ignitor.
- Pairs with the flame sense rod The flame sensor for these heaters is a separate part, and both are worth inspecting on the same visit.
- Handle by the base Ignitor elements are brittle. Touching or knocking the element is the quickest way to break a new one.

Product details
The Jandy R0386900 is the hot surface ignitor for the LX and LT Low NOx pool heaters. It is the genuine part for those models.
What it does
A hot surface ignitor takes the place of a standing pilot. When the heater calls for heat, current runs through the element until it glows, and the gas lights off that glowing surface. Nothing burns between cycles, which is why these heaters do not need relighting after a windy night.
When to replace it
The classic symptom is a heater that starts its sequence, runs the blower, and then locks out without ever lighting. Ignitor elements crack and burn out with age and thermal cycling, and once the element is open the heater has no way to light. The flame sense rod is a separate part on these heaters, so a unit that does light and then immediately shuts down is usually pointing at the sensor rather than the ignitor.
Fitting note
Confirm your heater is the Low NOx model, since the standard LX/LT ignitor is a different part number. Handle the new ignitor by its base. The element is brittle and easy to crack before it ever gets power.
