DuckcowsC FDXLIGN1930 Ignitor & Flame Sensor Kit for Hayward H-Series Heaters — Stainless Steel, Direct-Fit

If your Hayward H150–H400 series heater stalls, won’t light, or shows error codes related to ignition or flame sensing, this DuckcowsC replacement kit provides the core components you need to get the unit back to dependable operation. The kit is engineered to match Hayward universal H-series specifications and is made from durable stainless steel, ceramic and silicon nitride materials to withstand high temperatures and resist corrosion.

What exactly does this ignitor replacement kit include and why does it matter?

The FDXLIGN1930 kit provides a replacement ignitor and flame sensor assembly compatible with Hayward H-Series low NOx pool heaters. Replacing worn or damaged parts helps the heater detect and maintain a stable pilot or main burner flame, preventing frequent lockouts and unnecessary service calls. The kit’s materials are chosen for longevity and thermal stability.

• Direct-fit component for Hayward H150FDN–H400FDP models and HDF400
• Stainless steel, ceramic, and silicon nitride construction for heat resistance
• Integrated flame sensing and auto shut-off compatibility for safety
• Includes installation guidance in the packaging for easier swap-out

How difficult is installation and what tools do I need?

Installation is designed to be straightforward for someone comfortable with basic pool heater maintenance or a qualified technician. The kit includes step-by-step instructions to guide you through removing the old ignitor and fitting the new assembly. Typical installations take less than an hour depending on access and experience.

• Basic hand tools: screwdrivers, nut drivers, and pliers
• Turn off gas and power to the heater before starting
• Follow supplied instructions; professional service recommended if unsure

Will this part fit my specific Hayward model and restore operation?

This replacement is compatible with Hayward universal H-Series low NOx models including H150FDN, H150FDP, H200FDN, H200FDP, H250FDN, H250FDP, H300FDN, H300FDP, H350FDN, H350FDP, H400FDN, H400FDP and HDF400. Installing the correct ignitor and flame sensor typically resolves ignition failures caused by worn electrodes or degraded sensors, restoring normal heater start-up behavior when no other system faults exist.

• Cross-replaces part number FDXLIGN1930 for the listed Hayward H-series units
• Best for ignition/flame sensing failures, not for unrelated control board faults
• Keep other heater components inspected to ensure full repair success

What safety and quality features are included?

The kit incorporates materials and design choices intended to meet the operating demands of pool heaters: heat-resistant ceramics, robust stainless fittings, and silicon nitride sensor elements. It also supports the heater’s built-in safety systems like automatic shut-off and high-temperature sensing to maintain safe operation once installed correctly.

• High-temperature-stable ceramics and silicon nitride for consistent sensing
• Corrosion-resistant stainless steel for longer service life
• Supports heater auto shut-off and boiling point sensing functions

Who is this for: The DuckcowsC FDXLIGN1930 replacement ignitor kit is intended for pool owners, maintenance technicians, and service professionals who operate Hayward H-Series low NOx gas pool heaters and need a direct-fit, durable replacement for failed ignition or flame detection components. If your heater exhibits ignition errors or frequent lockouts and the rest of the system checks out, this kit provides a focused, quality solution to restore reliable firing and safer operation.
