It operates with two independent switching stages: a high set point of 0.85 inches W.C. and a low set point of 0.87 inches W.C. The switch monitors inducer and combustion air pressure to confirm safe operating conditions before allowing ignition to proceed. Licensed HVAC technicians install and service this component as part of routine furnace diagnostics and repair.\u003c\/p\u003e\n\u003cp\u003eThis pressure switch is suited for residential gas furnace installations where two-stage pressure sensing is required. It replaces OEM part number 101021-07 and is intended for systems that require independent high and low pressure confirmation during furnace operation. The dual set-point design allows the furnace control board to verify both stages of inducer operation before advancing through the ignition sequence.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eTwo independent switching stages for precise pressure monitoring\u003c\/li\u003e\n  \u003cli\u003eHigh set point at 0.85 inches W.C.\u003c\/li\u003e\n  \u003cli\u003eLow set point at 0.87 inches W.C.\u003c\/li\u003e\n  \u003cli\u003eOEM replacement for Lennox part number 101021-07\u003c\/li\u003e\n  \u003cli\u003eDesigned to confirm safe combustion air pressure prior to ignition\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eReplaces Lennox OEM part number 101021-07.

Shut off power to the furnace and close the gas supply valve before beginning service. Inspect the pressure tubing for cracks, blockages, or moisture before connecting to the new switch. Verify proper set-point operation after installation using a manometer before returning the system to service.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSet Point High\u003c\/strong\u003e: 0.85 inches W.C.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSet Point Low\u003c\/strong\u003e: 0.87 inches W.C.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSwitch Stages\u003c\/strong\u003e: 2\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: LENNOX\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 26W83\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"LENNOX","offers":[{"title":"Default Title","offer_id":51525053186354,"sku":"26W83","price":86.93,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/99d50bc73de4abe1e8fade71bd61e538.jpg?v=1785463326","url":"https:\/\/voomisupply.com\/products\/lennox-26w83-2-stage-pressure-switch-hvac","provider":"Voomi Supply","version":"1.0","type":"link"}
