Rheem-Ruud 42-105601-106 Pressure Switch Kit

The Rheem-Ruud 42-105601-106 Pressure Switch Kit is a critical OEM safety component designed for precise furnace air pressure monitoring and combustion control. Engineered as the direct replacement for 42-24335-95, this SPST pressure switch is factory-calibrated to a -0.35" WC set point, ensuring the draft inducer motor maintains the specific vacuum required for safe flue gas exhaustion. In technical environments, this part is essential for resolving furnace won't start conditions or pressure switch open fault codes common in high-efficiency gas furnaces like the UKKB, RKKB, and RKMB series.

This comprehensive kit includes a genuine factory-authorized part, 36-inch silicone rubber tubing, a mounting bracket, and specialized wire leads with self-cleaning contacts to prevent signal failure due to oxidation. By replacing a faulty furnace pressure switch with this exact OEM Rheem replacement part, technicians can eliminate short-cycling and ensure absolute compliance with factory safety sequences. The 42-105601-106 also supersedes legacy part numbers including 42-23649-02 and 42-24335-15, providing a standardized solution for modernizing older inducer safety circuits.

• Precise Calibration: Features a factory-set -0.35" WC trip point for accurate negative pressure sensing in residential and commercial units.
• Complete Replacement Kit: Includes silicone tubing, mounting hardware, and wire ties for a professional, "one-trip" service call.
• Enhanced Reliability: Utilizes self-cleaning contacts to maintain electrical continuity even in environments with high vibration or debris.
• Universal Compatibility: Serves as the verified direct replacement for 42-24335-95, 42-23649-02, and 42-24335-15.
• Safety Integrity: Prevents gas furnace ignition if the venting system is obstructed or the inducer motor fails to reach required RPM.

• What causes a pressure switch error on a Rheem furnace? Common causes include a blocked flue pipe, a cracked inducer hose, a clogged condensate drain, or a ruptured diaphragm within the switch itself.
• Can I use a universal pressure switch instead of the 42-105601-106? No. Because pressure settings are highly sensitive, installing a switch with a different WC rating can lead to dangerous ignition delays or premature system shutdowns.
• How do I test if the pressure switch is actually bad? Technicians should use a manometer to measure the actual vacuum produced by the inducer and a multimeter to check for continuity across the terminals when the rated pressure is reached.
