Bradford White 415-45865-00 Temp Switch
The Bradford White 415-45865-00 Temp Switch is a critical safety component designed for precise thermal monitoring within the blower housing assembly. This L165F-20 blower temperature switch is engineered to open the electrical circuit when internal temperatures reach 165°F, effectively shutting down the burner to prevent heat exchanger damage or unsafe operating conditions. Featuring a 20°F differential for reset, it ensures stable cycling performance in residential and commercial atmospheric or power-vented water heaters. As a direct OEM replacement part, it guarantees exact fitment and terminal alignment, reducing diagnostic time for service technicians. This limit switch is essential for maintaining the integrity of the flammable vapor ignition resistant (FVIR) system. When troubleshooting water heater lockout codes or blower motor failures, verifying the continuity of this thermal disc is a primary diagnostic step. Rely on this authentic high-limit cutout to restore factory-spec over-temperature protection and ensure reliable appliance operation.
Product Specifications and Performance Benefits- Precise Thermal Calibration: Fixed 165°F trip point with a 20°F reset margin for accurate thermal management.
- OEM Integration: Specifically designed for Bradford White blower assemblies to ensure seamless electrical connectivity.
- Safety Compliance: Acts as a primary fail-safe against restricted airflow or blocked venting scenarios.
- Durable Construction: Built to withstand high-cycle environments common in modern high-efficiency water heating systems.
What causes this switch to trip frequently?
Repeated tripping usually indicates restricted airflow, a failing blower motor, or excessive heat buildup within the burner chamber that exceeds the 165°F threshold.
Is the 415-45865-00 a manual or automatic reset switch?
This model is an automatic reset switch; however, if the thermal condition persists, the system will continue to cycle or enter a hard lockout depending on the control board logic.
Can I bypass this switch for testing purposes?
While jumping the terminals can confirm a failed switch during diagnostics, the unit must never be left operational without a functional limit switch due to fire and safety risks.
