Product Overview

The Hayward H-Series Heater Display Board Only | IDXL2DB1930 is a genuine replacement display board designed for compatible Hayward H-Series, Universal H-Series Low NOx, and H-Series IDL2 induced draft pool and spa heaters.

This board provides the heater’s user-facing display interface, allowing the unit to show temperature readings, settings, operating status, and diagnostic information. If the original display board is blank, damaged, unresponsive, difficult to read, or no longer communicating properly with the heater controls, replacing it with the correct board can help restore normal heater operation.

The IDXL2DB1930 is commonly referenced for Hayward heater models including H250IDL2, H350IDL2, H400IDL2, and select Universal H-Series Low NOx FD models when confirmed by model number, serial number, and parts diagram.

Installation Notes

This display board should be installed by a qualified pool heater technician. Pool heaters involve gas, electrical, ignition, and safety systems that must be serviced correctly.

Before installation, turn off power and gas to the heater. Allow the heater to cool before opening the control compartment. Carefully disconnect the existing display board and wiring, noting orientation and connector placement.
