Hayward Control Board Kit, FD

The Hayward FDXLICB1930 is the integrated control board kit for the Universal H-Series Low NOx FD heaters. It fits the H150FD, H200FD, H250FD, H300FD, H350FD and H400FD, including the ASME versions, in both pool and spa/hot tub service.

What it does

This is the main board in the heater. It runs the ignition sequence, monitors the safety and temperature inputs and drives the display and keypad on the front panel. When the heater will not respond, shows a persistent board fault or has suffered a surge or water damage in the control compartment, this is the part that gets replaced.

Before you order

Confirm your heater model on the rating plate ends in FD. If the keypad or wiring harness is also suspect, the bezel and keypad assembly and the complete FD wiring harness are separate parts.
