Quick overview
- Blower and board together Supplied as a matched kit rather than as two separately ordered parts.
- Genuine Hayward Factory part number IDXL2BWR1931 for H-Series Low NOx heaters.
- For Low NOx models Built for the H-Series Low NOx version, which is not interchangeable with the standard H-Series.
- IDL2 generation The IDL2 blower and control board assembly, so match the generation before ordering.
- Restores the burn cycle The blower and its board control combustion air, and the heater will not fire without them working together.
- Order by part number Heater electronics change across revisions, so IDXL2BWR1931 is the reference that matters.

Product details
The Hayward IDXL2BWR1931 is the LoNox IDL2 blower and control board kit for H-Series Low NOx pool heaters, supplied as a matched pair from the factory.
What the blower does
A Low NOx heater depends on controlled combustion air. The blower moves that air and the control board runs the blower, so a failure at either point stops the heater before it ever lights. Symptoms usually read as a heater that calls for heat, runs its checks and then locks out rather than firing.
Why it is a kit
Hayward supplies the blower and the board together for this generation. Fitting them as a set keeps the assembly matched to a single revision, which is the safer route on heater electronics that changed across model years.
Before you order
Confirm the heater is an H-Series Low NOx model and that the assembly is the IDL2 generation. The standard H-Series uses different parts.
