It guards against overcharge, blocked condenser airflow, and outdoor-fan failure — the leading causes of catastrophic compressor damage on R-410A systems.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eFunction: High-pressure cut-out (opens on rising pressure)\u003c\/li\u003e\n\u003cli\u003eTypical setpoint: ~610 PSI open \/ ~420 PSI auto-reset (R-410A)\u003c\/li\u003e\n\u003cli\u003eConnection: 1\/4 in.

Universal switches often carry generic setpoints that trip early or, worse, too late — leaving the compressor exposed. Match the OEM part to keep the safety chain intact.\u003c\/p\u003e\u003ch3\u003eInstallation Difficulty: Moderate (3\/5)\u003c\/h3\u003e\u003cp\u003eRequires recovering refrigerant or using the Schrader port, threading the switch onto the fitting, and reconnecting the low-voltage leads. Plan 30–45 minutes; confirm zero system pressure before removing the old switch. Best handled by an EPA-certified technician.\u003c\/p\u003e","brand":"Goodman","offers":[{"title":"Default Title","offer_id":63058259902835,"sku":"GOODMAN-15052","price":34.95,"currency_code":"USD","in_stock":true}],"url":"https:\/\/nationalhvacparts.com\/products\/oem-goodman-high-pressure-cut-off-switch-for-wph4430ahab-0130m00074","provider":"National HVAC Parts","version":"1.0","type":"link"}
