Rheem-Ruud 42-101956-12 Pressure Switch THPU32HP7Y Broad Compatibility: Replaces a wideThe Rheem Ruud 42 101956 12 Pressure Switch is an essential safety component designed for precise draft monitoring in high efficiency gas furnaces. Functioning as a 0. 50" WC SPST pressure switch, this OEM furnace part ensures that the draft inducer motor is moving sufficient air through the heat exchanger before the ignition sequence begins. When the inducer establishes the required negative pressure of 0. 50 inches water column, the single pole
