BSNOVT FDXLIGN1930 FD Ignitor is a direct replacement igniter and flame sensor for Hayward Universal H-Series low-NOx pool heaters, restoring reliable ignition and flame detection.

If your Hayward Universal H-Series heater (models H150FDN through H400FDP including HDF400) fails to light or shows ignition-related faults, this BSNOVT replacement kit gives you the components needed to get the unit back to dependable operation. Built from stainless steel, ceramic, and silicon nitride materials, the package replaces OEM part FDXLIGN1930 and is intended for technicians and DIYers comfortable with heater maintenance. The kit is sized to fit the specified Hayward family of low-NOx heaters and includes the full ignitor assembly for a straightforward swap.

How will this replacement ignitor affect heater ignition reliability?

Replacing a worn or failed ignitor with this kit restores consistent spark generation and accurate flame sensing, reducing intermittent misfires and lockouts. The durable construction reduces the chance of premature failure in high-heat, corrosive environments.

• Direct-fit replacement for part FDXLIGN1930 to simplify installation.
• Materials like silicon nitride and ceramic retain performance at high temperatures.
• Precision flame sensing lowers false shutoffs and improves burner stability.

What models and applications is the FDXLIGN1930 kit compatible with?

This BSNOVT kit is designed specifically for Hayward Universal H-Series low-NOx pool heaters across multiple capacities, covering both in-ground and above-ground pool setups. Confirm your model number before ordering to ensure compatibility.

• Fits H150FDN, H150FDP, H200FDN, H200FDP and higher-capacity H250–H400 series models.
• Works with both natural-gas and propane configurations when matched to the heater model.
• Supplied as a single complete ignitor replacement for rapid swap-out.

How difficult is installation and what safety features are included?

Installation is typically straightforward for a trained service technician or experienced DIYer; the kit replaces the original ignitor location using the heater's existing mounting. The assembly incorporates an auto shut-off design and a boiling-point (overheat) sensor to help protect the heater during fault conditions.

• Direct replacement design minimizes wiring and mounting modifications.
• Auto shut-off feature helps prevent unsafe ignition cycles.
• Boiling-point sensor adds thermal protection if abnormal temperatures occur.

What materials and build qualities support long-term service life?

The BSNOVT ignitor kit uses corrosion-resistant and heat-stable materials to endure continuous exposure inside combustion chambers. These choices help maintain ignition performance over many heating cycles and lower the frequency of replacements.

• Stainless-steel components resist rust and mechanical wear.
• Ceramic insulation stands up to thermal stress and electrical isolation needs.
• Silicon nitride tip improves high-temperature durability where spark and flame contact occur.

Who is this for: This ignitor replacement kit is intended for pool owners, service technicians, and maintenance professionals who operate Hayward Universal H-Series low-NOx heaters and need a reliable, OEM-equivalent ignitor swap. If your heater is experiencing ignition failures, flame-sensor faults, or recurring lockouts, this direct-fit kit offers a durable, engineered solution to restore normal operation—just verify model compatibility and follow proper installation and safety procedures.
