It monitors low-side suction pressure and opens the control circuit to stop the compressor when pressure drops too low — protecting against loss-of-charge, a frozen coil, or restricted refrigerant flow. When it fails, the compressor may refuse to start or may run unprotected during a charge loss.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eOEM part number: 0130M00075\u003c\/li\u003e\n\u003cli\u003eType: low pressure (loss-of-charge) switch\u003c\/li\u003e\n\u003cli\u003eFunction: opens control circuit on low suction pressure\u003c\/li\u003e\n\u003cli\u003eFits: Goodman WGPH4549AMAB package unit\u003c\/li\u003e\n\u003cli\u003eConnection: factory spade terminals \/ refrigerant fitting\u003c\/li\u003e\n\u003cli\u003eAction: auto reset per OEM spec\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe OEM switch carries Goodman's exact cut-out and cut-in pressure setpoints. Aftermarket switches with mismatched setpoints can leave the compressor unprotected or cause repeated nuisance trips. For a low-cost safety component that guards an expensive compressor, the genuine OEM part is the smart choice.\u003c\/p\u003e\u003ch3\u003eInstall Difficulty\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eEasy to moderate\u003c\/strong\u003e — port-mounted versions typically thread onto a Schrader fitting with two spade wires and no refrigerant recovery; brazed-in versions need an EPA-certified tech. Plan 15–35 minutes. Always disconnect power before servicing and confirm the wiring matches the unit diagram.\u003c\/p\u003e","brand":"Goodman","offers":[{"title":"Default Title","offer_id":63057215848819,"sku":"GOODMAN-1054","price":27.95,"currency_code":"USD","in_stock":true}],"url":"https:\/\/nationalhvacparts.com\/products\/oem-goodman-low-pressure-switch-for-wgph4549amab-0130m00075-1","provider":"National HVAC Parts","version":"1.0","type":"link"}
