Bradford White 415-47845-05 Pilot

Professional-grade Bradford White 415-47845-05 Natural Gas Pilot Assembly is a high-precision OEM replacement engineered for peak ignition reliability in atmospheric vent water heaters. This Honeywell 17/26 pilot assembly features a robust thermopile/thermocouple integration designed to interface seamlessly with Honeywell gas control valves, ensuring stable flame sensing and consistent burner ignition. Optimized for natural gas service, this assembly is a critical component for maintaining the safety and efficiency of Bradford White Defender Safety System models, effectively resolving common field issues such as intermittent pilot outage, weak millivolt signals, or failure to ignite. The assembly is rated for systems up to 65 gallons and facilitates a direct-fit installation to minimize downtime. As a genuine manufacturer part, it maintains the strict tolerance levels required for flammable vapor ignition resistant (FVIR) compliance. Contractors should note that this unit is the verified technical successor to several legacy part numbers, providing a standardized solution for a wide range of Bradford White MI, M1, M2XT, and RG residential series tanks.

Key Benefits for Technicians:

• Direct OEM Compatibility: Specifically designed for the Bradford White M-I-40T6FBN-TOPTP and related MI/RG series atmospheric models.
• Universal Replacement: Serves as the official successor for part numbers 233-47845-05, 233-47845-01, 233-47845-02A, 233-47845-03, and 233-47845-05A.
• Precision Ignition: Includes the Honeywell 17/26 NG pilot burner and integrated sensing components for reliable millivolt production.
• System Integrity: Ensures continued compliance with FVIR safety standards in residential gas water heater applications.
• Simplified Service: Factory-configured for natural gas, eliminating the need for field adjustments to the pilot orifice or air intake.

Common Questions & Technical Support:

Will this work if my water heater uses Liquid Propane?
No, this assembly is strictly for natural gas models. Installing an NG assembly on an LP unit creates a high-pressure fire hazard.

Why does my pilot keep going out after installation?
Verify that the thermocouple is fully seated in the bracket and providing a consistent signal to the gas valve. Check for any debris in the ScreenLok flame arrestor that may be starving the pilot of combustion air.

Is 233-47845-05 the same part?
Yes. Bradford White frequently uses 233-47845-05 and 415-47845-05 interchangeably; they are identical in form, fit, and technical performance.
