When it fails, you may notice short-cycling, a no-start condition, or recurring pressure-fault lockouts. This factory-matched replacement uses the precise trip and reset points your model calls for, delivering accurate protection and steady performance. Installation is quick: disconnect power, isolate refrigerant per code if required, unthread the old switch, and connect the new one with its quick-connect terminals — a 20 to 30 minute task for most technicians. Installing the correct OEM switch eliminates nuisance trips and protects your most expensive component from costly failure. Genuine Payne construction holds its cut-out calibration reliably year after year. In stock and ready — orders placed before 3PM CST ship the same day so your system gets back to safe, dependable cooling fast. Don't risk your compressor on an out-of-spec generic part.\u003c\/p\u003e\n\u003ch2\u003eCompatibility\u003c\/h2\u003e\n\u003cp\u003eThis part is compatible with Payne model PA12NA018000AAAA.\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":"Payne","offers":[{"title":"Default Title","offer_id":62942556127603,"sku":"payne-pressure-switch-pa12na018000aaaa","price":48.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0984\/1190\/5395\/files\/nhvac-pressure-switch-pa12na018000aaaa.jpg?v=1781475790","url":"https:\/\/nationalhvacparts.com\/products\/payne-pressure-switch-pa12na018000aaaa","provider":"National HVAC Parts","version":"1.0","type":"link"}
