Bradford White 233-40248-05 Pilot Assembly

The Bradford White 233-40248-05 Pilot Assembly is a critical OEM replacement part designed for specific natural gas water heater models equipped with the Defender Safety System. This assembly functions as a direct replacement for the discontinued 233-41801-05B, ensuring continued reliable ignition and flame sensing. Engineered for high-temperature durability, this pilot burner assembly includes the thermopile, thermocouple, and igniter wire required to restore the standing pilot system to manufacturer specifications. Proper installation maintains the integrity of the CCT (Flammable Vapor Ignition Resistant) system, preventing nuisance shutdowns and intermittent combustion issues. When performing a water heater pilot repair, technicians should verify the orifice size and millivolt output to ensure compatibility with the existing gas control valve. This kit is built to withstand the rigorous cycling of residential and light commercial applications, providing the necessary thermal feedback to the gas valve for safe operation.

Key Benefits

• OEM Compatibility: Specifically engineered for a precise fit within Bradford White combustion chambers.
• Streamlined Installation: Integrated lead wires and connectors reduce field labor time during pilot assembly replacement.
• Direct Supersession: Serves as the official factory-authorized substitute for part 233-41801-05B.
• System Reliability: High-grade sensors ensure consistent millivolt generation for stable burner operation.

Common Questions

Why is my Bradford White pilot not staying lit?
A common cause is a degraded thermopile or a clogged pilot orifice. If the voltage signal to the gas valve is insufficient, the safety magnet will drop out, extinguishing the flame. Replacing the entire 233-40248-05 assembly ensures all ignition components are refreshed.

Can I use this assembly on an LP (Propane) unit?
No, this specific part number is calibrated for natural gas water heaters. Using a natural gas pilot on an LP system creates a significant safety hazard due to incorrect orifice sizing.

What does the 233-40248-05 include?
This is a complete pilot burner kit containing the pilot tube, electrode, and sensing elements, allowing for a comprehensive overhaul of the pilot system.
