This switch confirms that the induced-draft blower has established proper venting before the ignition sequence is allowed to proceed. If adequate draft is not sensed, the switch keeps the burners locked out — protecting against dangerous flue-gas conditions.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eOEM Part Number: B1370126\u003c\/li\u003e\n\u003cli\u003eSet Point: -0.40 in.

The \u003cstrong\u003egenuine Goodman OEM switch\u003c\/strong\u003e is calibrated to factory spec. A generic switch with a slightly different trip point can cause nuisance lockouts or, worse, fail to protect properly. For any combustion-safety component we strongly recommend OEM; a verified-compatible generic is offered only where set point and configuration match exactly.\u003c\/p\u003e\u003ch3\u003eInstallation Difficulty\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eEasy (2 of 5).\u003c\/strong\u003e Typically 15–20 minutes. Disconnect power, note the hose and wire positions, then transfer the draft hose and terminals to the new switch. Confirm the hose is free of blockage and the switch closes on an ignition cycle. Because it is a safety control, verify correct operation — or have a licensed HVAC technician perform the replacement.\u003c\/p\u003e","brand":"Goodman","offers":[{"title":"Default Title","offer_id":63058193940851,"sku":"GOODMAN-13194","price":26.95,"currency_code":"USD","in_stock":true}],"url":"https:\/\/nationalhvacparts.com\/products\/oem-goodman-0-40-in-wc-pressure-switch-for-gup050-2a-b1370126","provider":"National HVAC Parts","version":"1.0","type":"link"}
