This OEM Goodman switch is factory-calibrated to the exact trip point the AMVC board expects, so first-stage ignition sequences reliably. Generic replacements frequently miss this tolerance.\u003c\/p\u003e\u003ch3\u003eInstallation Difficulty: Easy to Moderate\u003c\/h3\u003e\u003cp\u003eCut power, move the vacuum tube and wiring to the new switch, and mount in the original location. Confirm the sensing hose is clear of condensate and cracks, then test a low-fire heat call to verify the switch closes and the furnace lights normally.\u003c\/p\u003e","brand":"Goodman","offers":[{"title":"Default Title","offer_id":63057888739699,"sku":"GOODMAN-8888","price":32.95,"currency_code":"USD","in_stock":true}],"url":"https:\/\/nationalhvacparts.com\/products\/oem-goodman-10-wc-pressure-switch-for-amvc950905dxac-20197308","provider":"National HVAC Parts","version":"1.0","type":"link"}
