This normally-open switch closes at a set-point of \u003cstrong\u003e-0.60 inches water column (WC)\u003c\/strong\u003e, confirming the inducer motor has established proper venting airflow before the ignition sequence begins. If adequate draft isn't proven — due to a blocked vent, failing inducer, cracked hose, or clogged drain trap — the switch stays open and safely prevents ignition, protecting against flue-gas spillage.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eOEM Part Number: 20197310\u003c\/li\u003e\n\u003cli\u003eType: Air \/ draft pressure switch\u003c\/li\u003e\n\u003cli\u003eSet Point: -0.60\" WC (water column)\u003c\/li\u003e\n\u003cli\u003eContacts: Normally Open (NO), close on negative pressure\u003c\/li\u003e\n\u003cli\u003eFits: Goodman GKS91155DXAA gas furnace\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003ePressure-switch set-point and contact configuration are matched to the furnace's specific venting design. The -0.60\" WC rating and NO contacts must be exact — a mismatched switch will either fail to prove draft (no ignition) or prove it prematurely (a safety hazard). Genuine OEM guarantees the correct calibration and tubing ports; generics frequently differ. For this safety control, insist on OEM.\u003c\/p\u003e\u003ch3\u003eInstall Difficulty: Moderate\u003c\/h3\u003e\u003cp\u003eCut power, mark and swap the spade wires, transfer the pressure hose to the same port, and remount with the original screws. Manageable for an experienced DIYer — verify the -0.60\" WC rating stamped on the switch matches the original before installing.\u003c\/p\u003e","brand":"Goodman","offers":[{"title":"Default Title","offer_id":63057147167091,"sku":"GOODMAN-20197310","price":42.95,"currency_code":"USD","in_stock":true}],"url":"https:\/\/nationalhvacparts.com\/products\/oem-goodman-0-60-wc-no-pressure-switch-for-gks91155dxaa-20197310","provider":"National HVAC Parts","version":"1.0","type":"link"}
