Hayward FDXLFWP1930 Field Wiring Panel Kit (Fuse Board) for Universal H-Series Low NOx FD Heaters
The Hayward FDXLFWP1930 is a genuine OEM field wiring panel kit (often referred to as the fuse board) for Hayward Universal H-Series Low NOx “FD” pool heaters. This assembly provides the heater’s primary field wiring connection interface and helps distribute incoming power safely to the heater’s control circuits.
Fits / Compatibility
- Hayward Universal H-Series Low NOx FD heaters: H150FDN, H150FDP, H200FDN, H200FDP, H250FDN, H250FDP, H300FDN, H300FDP, H350FDN, H350FDP, H400FDN, H400FDP
- Also commonly listed for H500FDN / H500FDP (verify your heater model and parts diagram)
- Used on many ASME/commercial Universal H-Series FD heater configurations (model/revision dependent)
What It Does
- Provides the terminal/connection point for field wiring inside the heater
- Functions as the heater’s fuse board/power distribution panel for supported circuits
- Helps ensure reliable power delivery to the heater’s electronics when the original panel is damaged or corroded
Common Reasons to Replace
- Heater won’t power up and diagnostics point to a failed/damaged fuse board
- Burned terminals, heat damage, or corrosion on the wiring panel
- Moisture intrusion inside the heater cabinet causing board damage
- Intermittent power issues after confirming supply voltage and wiring integrity
Installation Notes
- Turn off power at the breaker before opening the heater.
- Label or photograph all wiring connections before removal for correct reinstallation.
- If the original failure was moisture-related, fix the sealing/conduit issue before installing the new panel.
- Electrical service should be performed by a qualified technician and must follow applicable codes.

Maintenance Tips
- Keep the heater cabinet sealed and dry—moisture is a leading cause of electrical panel and board failures.
- If the heater loses power intermittently, inspect supply voltage, wiring terminals, and any signs of heat discoloration at connections.
- Maintain proper water flow (clean baskets/filters) to reduce nuisance faults that can lead to repeated cycling and electrical stress.
