It monitors the negative pressure created by the inducer draft motor and verifies proper venting before the control board permits ignition. If the switch detects a blocked flue, a failing inducer, or a cracked pressure hose, it opens the circuit and prevents the burners from firing, protecting your home from unsafe combustion conditions. A faulty switch is a common cause of furnaces that hum but never light, or that lock out after a few seconds. Built to factory specifications, this direct replacement matches the original setpoint and connector so no rewiring or guesswork is needed. Installation is a moderate DIY job for a handy homeowner: shut off power, photograph the hose and wire connections, swap the switch, and reconnect. Most techs complete it in 15 minutes. Pairs perfectly with the GB1AAV036090AAJA inducer assembly. Ships same-day when you order before 3PM CST so you can restore heat fast.\u003c\/p\u003e\n\u003ch2\u003eCompatibility\u003c\/h2\u003e\n\u003cp\u003eThis part is compatible with Carrier model GB1AAV036090AAJA.\u003c\/p\u003e\n\u003ch2\u003eShipping\u003c\/h2\u003e\n\u003cp\u003eSame-day shipping before 3 PM CST. 30-day returns on uninstalled parts.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"Carrier","offers":[{"title":"Default Title","offer_id":62942812602739,"sku":"carrier-pressure-switch-gb1aav036090aaja","price":44.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0984\/1190\/5395\/files\/nhvac-pressure-switch-gb1aav036090aaja.jpg?v=1781469609","url":"https:\/\/nationalhvacparts.com\/products\/carrier-pressure-switch-gb1aav036090aaja","provider":"National HVAC Parts","version":"1.0","type":"link"}
