Bradford White 415-45867-01 Pressure Switch
The Bradford White 415-45867-01 Pressure Switch is a critical safety component designed for power vent water heaters. As a 0.75" WC SPST pressure switch, it is factory-calibrated to a fixed set point of 0.75 inches of water column, ensuring the draft inducer blower is moving sufficient air before the ignition sequence begins. This Single-Pole Single-Throw (SPST) switch remains normally open (NO) and closes only when the specific negative pressure threshold is reached, preventing the risk of carbon monoxide backup due to venting obstructions or blower motor failure. Built for OEM compatibility, this switch features a rugged housing and standard spade terminals for a secure electrical connection. For field service, use a manometer to verify that the inducer is pulling at least 0.75" WC to rule out blocked intake pipes or condensate buildup in the pressure switch tubing. Replacing a faulty switch with this genuine Bradford White replacement part ensures the gas control valve receives the correct signal to initiate the spark-to-pilot ignition system.
Key Benefits
- OEM Reliability: Exact Bradford White 415-45867-01 replacement ensures proper fitment without the need for mounting modifications.
- Precise Calibration: Fixed 0.75" WC set point maintains the integrity of the combustion safety circuit.
- System Protection: Effectively prevents the burner from firing if the vent pipe is restricted or the inducer fan is underperforming.
- Standard Connectivity: Utilizes a SPST configuration and standard terminals for rapid 1:1 swap-outs during service calls.
- Safety Compliance: Crucial for resolving 3-flash LED error codes related to pressure switch faults on Defender Safety System models.
Common Questions
What does a 3-blink error code mean on my Bradford White water heater?
A 3-blink code typically indicates a pressure switch failure. This means the 0.75" WC SPST switch failed to close within 30 seconds of the inducer blower starting, or it opened during a heating cycle. Verify that the venting is clear and the tubing is not cracked before replacing the switch.
How do I test the 415-45867-01 with a multimeter?
With the unit powered down, disconnect the wires and check for continuity. The switch should be open. Then, with the draft inducer running, the switch should close and show near 0 ohms. If it remains open while the blower is at full speed, the switch is likely defective or the negative pressure is insufficient.
Can I use this switch as a universal replacement?
No. Pressure switches are safety-critical and calibrated to specific water heater models and vent lengths. Always match the WC rating and part number 415-45867-01 exactly to ensure safe flue gas evacuation.
