Information About 42-24195-03
The 42-24195-03 is a factory-authorized air pressure switch engineered for use in Rheem and Ruud residential gas furnaces. It operates by sensing negative pressure generated by the inducer motor, ensuring that proper venting conditions are met prior to burner activation. Built with a precision diaphragm and calibrated to 0.40 inches water column, it provides accurate and repeatable switching performance. This model is commonly used across multiple furnace series including UGRA, RGRA, UGRB, RGRB, and others, and serves as a direct replacement for earlier part numbers while maintaining strict safety compliance.
Key Features:
- Calibrated Pressure Setpoint: Precisely set to 0.40" WC for accurate airflow verification
- Furnace Safety Protection: Prevents operation under unsafe draft or venting conditions
- OEM Factory Authorized Part: Ensures exact fit and performance for Rheem/Ruud systems
- Wide Model Compatibility: Used in UGRA, RGRA, UGRB, RGRB, UGRJ, RGRJ, and more
- Direct Replacement Design: Replaces part numbers 42-24012-02 and 42-24387-02
- Durable Diaphragm Mechanism: Provides consistent pressure sensing over time
- Integrated Drain Port: Helps manage condensation within the pressure tubing system
- Electrical Switching Reliability: Stable contact operation under HVAC load conditions
- Easy Installation: Designed for quick replacement with standard tubing and connectors
- Corrosion-Resistant Materials: Suitable for furnace environments with moisture exposure
- Critical Safety Component: Must match exact pressure rating to maintain system safety
The 42-24195-03 delivers the reliability and precision required for safe furnace draft monitoring and combustion control.
