Pressure switches monitor the negative pressure created by the inducer motor during the heating cycle, confirming proper venting conditions before allowing the gas valve and ignition sequence to proceed. This switch is a direct OEM-replacement component engineered to match original manufacturer specifications for fit and function. At 0.23 pounds and compact dimensions, it installs quickly in the pressure switch bracket without modification. HVAC technicians working on residential gas furnaces will find this a straightforward swap during a no-heat or pressure-switch fault diagnosis.\u003c\/p\u003e\n\u003cp\u003eThis pressure switch is intended for use in residential gas furnaces where the original switch has failed, is stuck open or closed, or shows erratic behavior during the inducer pre-purge and post-purge cycles. Compatible units include the N80ESL0451412A1, N80VSL, and N80ESN series furnaces, among others. Always verify the replacement part number against the unit nameplate or service literature before installation to confirm fitment for the specific model on the job.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eOEM-replacement pressure switch built to original manufacturer specifications\u003c\/li\u003e\n  \u003cli\u003eMonitors inducer motor negative pressure to ensure safe furnace ignition sequencing\u003c\/li\u003e\n  \u003cli\u003eCompact form factor at 3.55 x 3.35 x 3 inches for direct bracket installation\u003c\/li\u003e\n  \u003cli\u003eLightweight at 0.23 pounds for easy single-tech handling during service calls\u003c\/li\u003e\n  \u003cli\u003eDesigned for residential gas furnace applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eCompatible with International Comfort Products furnace models including N80ESL0451412A1, N80VSL, and N80ESN series.

Shut off power to the furnace at the disconnect or breaker and turn the gas supply to the off position before beginning any service work. Disconnect the rubber hose port connections and low-voltage wiring harness from the existing switch, noting or photographing wire positions before removal. After installing the replacement switch, restore power and run the furnace through a full call-for-heat cycle to confirm the inducer pre-purge pressure signal closes the switch and the ignition sequence proceeds normally.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 3.55 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 3.35 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.23 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: International Comfort Products\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 1191249\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HEATINGVARIOUSMFG-GENERIC","offers":[{"title":"Default Title","offer_id":51467410538802,"sku":"1191249","price":160.26,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/313946882.png?v=1783903824","url":"https:\/\/voomisupply.com\/products\/icp-1191249-pressure-switch-furnace-parts","provider":"Voomi Supply","version":"1.0","type":"link"}
