It monitors draft pressure to verify proper inducer operation before allowing ignition to proceed, functioning as a critical safety device within the combustion air proving circuit. The switch is rated at 0.18 inches water column (WC), which defines its setpoint for making or breaking the control circuit. Licensed HVAC technicians install and replace this component as part of routine furnace diagnostics and safety-circuit service.\u003c\/p\u003e\u003cp\u003eThis pressure switch is suited for residential gas furnace installations where a draft inducer assembly is present. It connects to the inducer housing or flue system via a rubber pressure hose and interfaces with the integrated furnace control board. Common service scenarios include nuisance lockouts caused by a failed or out-of-calibration pressure switch, inducer motor issues, or blocked condensate or flue passages. Verify the cause of lockout before replacing the switch to avoid repeat callbacks.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSPST configuration opens or closes a single control circuit based on sensed draft pressure\u003c\/li\u003e\n\u003cli\u003e0.18 inches WC setpoint for precise draft proving in low-pressure sensing applications\u003c\/li\u003e\n\u003cli\u003eDesigned as a direct replacement for OEM pressure switches in compatible gas furnace systems\u003c\/li\u003e\n\u003cli\u003eCompact form factor fits standard inducer-port hose connections\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement pressure switch for residential gas furnace control systems requiring a 0.18 inches WC SPST draft-proving switch.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed HVAC technician. Shut down power to the furnace and close the gas supply valve before servicing any pressure switch or combustion safety circuit. Inspect the pressure hose, hose barb fittings, and inducer port for cracks, clogs, or moisture before installing the new switch, as these conditions can cause the replacement switch to fault. Work should comply with applicable local mechanical codes and the furnace manufacturer installation instructions.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSwitch Type\u003c\/strong\u003e: SPST (Single-Pole Single-Throw)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePressure Setpoint\u003c\/strong\u003e: 0.18 inches WC\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: RCD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: hk06wc090\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"RCD","offers":[{"title":"Default Title","offer_id":51233608368434,"sku":"HK06WC090","price":90.61,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/307626086.jpg?v=1780104520","url":"https:\/\/voomisupply.com\/products\/rcd-hk06wc090-spst-pressure-switch-0-18-inches-wc","provider":"Voomi Supply","version":"1.0","type":"link"}
