It monitors pressure changes within the combustion air or inducer circuit and opens or closes the control circuit in response to those changes. The switch activates at 1.60 inches water column on a falling pressure signal, confirming that the inducer motor has established proper draft before allowing ignition to proceed. It measures 4.65 inches long, 3.85 inches wide, and 3.8 inches tall, weighing 0.215 pounds. Licensed HVAC technicians install this switch as a direct OEM replacement when a furnace fails a pressure switch diagnostic.\u003c\/p\u003e\u003cp\u003eThis switch is suited for residential gas furnace systems where draft-proving or combustion-air proving is required. It is a genuine OEM replacement part, meaning it matches the original factory specifications for the equipment it serves. Compatible units include the FC9S040A12UP11, FC9S040A12UP11A, and FL9S040A12UP11A, among others. Installers replacing a failed or out-of-spec pressure switch during a service call will find this part drops into the existing mounting location without modification.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eActivates at 1.60 inches water column on a falling pressure signal\u003c\/li\u003e\n\u003cli\u003eSingle-pole, normally open configuration for standard furnace control wiring\u003c\/li\u003e\n\u003cli\u003eGenuine OEM replacement part engineered to factory specifications\u003c\/li\u003e\n\u003cli\u003eCompact form factor fits existing mounting hardware without alteration\u003c\/li\u003e\n\u003cli\u003eLightweight at 0.215 pounds for easy handling during install\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eCompatible with FC9S040A12UP11, FC9S040A12UP11A, and FL9S040A12UP11A units, as well as additional YORK furnace models.

Before servicing, shut off power to the furnace at the disconnect switch and allow the inducer assembly to come to a full stop. Verify the new switch activation pressure matches the original specification before reinstalling hose connections. Follow all applicable local codes and manufacturer service documentation when replacing pressure-sensing components.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eActivation Pressure\u003c\/strong\u003e: 1.60 inches water column on fall\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConfiguration\u003c\/strong\u003e: Single Pole Normally Open\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 4.65 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 3.85 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 3.8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.215 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: YORK\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 2440000000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"YORK","offers":[{"title":"Default Title","offer_id":68093273735474,"sku":"2435264000","price":58.31,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ee137015de918bd7068a1d6976831abc.gif?v=1793234272","url":"https:\/\/voomisupply.com\/products\/york-2440000000-air-pressure-switch-1-60-on-fall","provider":"Voomi Supply","version":"1.0","type":"link"}
