Hayward H-Series Display Board, IDXL2DB1930

The Hayward IDXL2DB1930 is the genuine display board for the H-Series heater family. It is the panel that shows set temperature, operating state and the diagnostic codes used to trace a fault.

What it fits

Hayward lists it for ASME heaters, H-Series Low NOx induced draft heaters and the Universal H-Series Low NOx range, covering models H250IDL2, H350IDL2, H400IDL2, H150FD, H200FD, H250FD, H300FD, H350FD, H400FD and H500FD, in both pool and spa applications.

Check the build date

This board is for heaters manufactured after 8/19/2002. That date is the dividing line in the H-Series control platform, so read the rating plate before ordering rather than going by model number alone.

When to replace it

A display that stays dark with power present, shows scrambled segments, or refuses to accept input at the buttons points at the display board rather than the heater itself. Replacing it restores the interface and the fault code readout that the rest of the diagnosis depends on.
