This switch monitors draft in the induced-draft venting system and safely locks out ignition if adequate airflow is not detected — protecting your home from incomplete combustion and flue blockages. A weak, stuck, or failed pressure switch is one of the most common causes of a furnace that ignites briefly then shuts down, or that never fires at all.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eTrip Point:\u003c\/strong\u003e -0.10 in.

Generic replacements often carry looser calibration tolerances that can trigger nuisance lockouts in cold weather or, worse, fail to trip when they should.

Verify the correct trip rating stamped on the old switch before installing, and test furnace operation through a full heat cycle afterward. If you are not comfortable working around gas appliances, hire a licensed HVAC technician.\u003c\/p\u003e","brand":"Goodman","offers":[{"title":"Default Title","offer_id":63058119000435,"sku":"GOODMAN-11345","price":32.95,"currency_code":"USD","in_stock":true}],"url":"https:\/\/nationalhvacparts.com\/products\/oem-goodman-0-10-in-wc-pressure-switch-for-gmh950904cxae-20197308","provider":"National HVAC Parts","version":"1.0","type":"link"}
