Rheem-Ruud 42-24194-83 Furnace Pressure Switch SPST 0.1" WC OEM Replacement

The Rheem-Ruud 42-24194-83 is a genuine OEM Single-Pole Single-Throw (SPST) furnace pressure switch rated at 0.1" water column (WC). Designed for use in Rheem, Ruud, and Weatherking gas furnaces, this pressure switch monitors inducer motor draft pressure to verify safe combustion venting before allowing the furnace to fire.

As a safety-critical component, this switch opens or closes an electrical circuit based on the measured pressure within the system. If the inducer fails to develop the correct draft pressure, the switch prevents ignition, protecting the appliance and occupants from combustion hazards.
