• Enhanced Reliability: Designed specifically for the Bradford White Defender Series to resolve recurring pilot outages.
• Complete Assembly: Includes the pilot tube, electrode, and sensing element to streamline the maintenance process.
• Optimized Millivolt Output: Provides a stable signal to the burner control for precise gas flow management.

Common Technical Questions

How do I troubleshoot a pilot that will not stay lit on a Bradford White unit?
First, inspect the thermopile output and check for manifold pressure drops. If the thermopile is failing to generate sufficient millivolts, replacing the entire 233-45515-00 assembly is the standard procedure to restore the thermocouple signal and gas valve hold-in circuit.

Is the 233-45515-00 compatible with older 233-40876-02 models?
Yes, this is the official manufacturer-designated superseded part number. It is built to the same specifications and replaces the legacy pilot burner assembly found in many natural gas water heaters.

What causes pilot assembly failure in high-efficiency atmospheric units?
Common failure points include scorched thermopiles, clogged orifices from gas impurities, or damaged ceramic insulators on the electrode. Replacing the assembly ensures clean ignition and accurate flame rectification.
