Description
The Rheem 42-106081-01 is a genuine OEM (Original Equipment Manufacturer) pressure switch, a crucial safety and operational component used in Rheem, Ruud, and WeatherKing gas furnaces. This switch is part of the furnace’s air-proving circuit, designed to monitor the successful flow of combustion air and the proper venting of exhaust gases. It is typically a low-range, snap-action type switch, which must close to signal the integrated furnace control board that the induced draft motor is operating correctly and that it is safe to proceed with ignition.
If the switch does not detect the minimum required pressure (often 0.2 inches of water column (in. W.C.) as found on similar models), it will remain open, preventing the furnace from igniting. This protects the home and equipment from hazardous conditions like blocked vents or heat exchanger failures. When replacing this part , it is vital to use the exact replacement to maintain the factory’s safety calibrations. The 42-106081-01 is often compatible with high-efficiency gas furnace models like the R97MV and R97V-KSA series.
Key Features:
- Genuine OEM Component: Factory-authorized part from Rheem/Ruud, ensuring exact fit and pressure calibration for safe and reliable operation.
- Air-Proving Safety Function: Monitors the vacuum or pressure created by the inducer motor to ensure proper air flow for combustion and venting.
- Fixed Pressure Setting: Calibrated to a specific low-pressure rating (commonly 0.2 in. W.C.) that must be met before the burner is allowed to fire.
- Self-Cleaning Contacts: Features self-cleaning contacts for enhanced durability and stable switching performance over the component’s lifespan.
