It provides loss-of-charge and low-ambient protection, preventing the compressor from running under a refrigerant leak or frozen-coil condition that would otherwise destroy it.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eFunction: Low-pressure cut-out (opens on falling pressure)\u003c\/li\u003e\n\u003cli\u003eTypical setpoint: ~20 PSI open \/ ~45 PSI auto-reset (R-410A)\u003c\/li\u003e\n\u003cli\u003eConnection: 1\/4 in.

Generic replacements with mismatched setpoints can either nuisance-trip in cold weather or fail to protect the compressor during a slow leak. OEM keeps the factory safety logic intact.\u003c\/p\u003e\u003ch3\u003eInstallation Difficulty: Moderate (3\/5)\u003c\/h3\u003e\u003cp\u003eThread onto the suction-line Schrader port and reconnect the low-voltage leads. Verify the system is not under pressure at the port before servicing. About 30 minutes for an EPA-certified technician; homeowners should defer to a pro for sealed-system work.\u003c\/p\u003e","brand":"Goodman","offers":[{"title":"Default Title","offer_id":63058259935603,"sku":"GOODMAN-15053","price":22.95,"currency_code":"USD","in_stock":true}],"url":"https:\/\/nationalhvacparts.com\/products\/oem-goodman-low-pressure-switch-for-wph4430ahab-heat-pump-0130m00075","provider":"National HVAC Parts","version":"1.0","type":"link"}
