Product details

The Hayward IDXL2ICB1931 is the integrated control board for H-Series Low NOx pool heaters, models H250IDL2, H350IDL2 and H400IDL2, built after 09/2004. It is the genuine Hayward replacement.

What it does

Hayward consolidated several jobs onto one board on these heaters. It manages ignition, regulates temperature and runs the diagnostic monitoring that reports faults back to the display. One assembly, several functions, which makes installation simple and makes the board central to whether the heater runs at all.

Check the build date

The date qualifier on this listing is not decoration. Hayward revised the control on the H-Series, and this board is the version for units built after 09/2004. The build date is on the rating plate. A heater older than that takes a different board, and the two are not interchangeable.

Before you swap it

A failing control board can imitate almost any other fault, so almost any other fault gets blamed on the board. Before ordering, confirm gas supply, the igniter, the sensors and the grounding are all healthy. If one of those is the true fault, a new board will fail the same way the old one did.

Questions and answers

What people ask about this product, answered by our pool techs.

Which heaters does this board fit?
Hayward H-Series Low NOx models H250IDL2, H350IDL2 and H400IDL2.
Why does the date matter?
This board is specified for units built after 09/2004. Hayward changed the control on the H-Series, so a heater built before that date takes a different board. The build date is on the heater rating plate.
What does the board control?
Ignition, temperature regulation and diagnostic monitoring, all on one integrated assembly rather than as separate modules.
Should I replace the board or keep troubleshooting?
Control boards get blamed for faults that belong to sensors, gas supply, the igniter or grounding. Confirm the inputs are good first, because a board swap that does not address the real fault often takes the new board with it.
