Wired into the low-voltage control circuit, it opens when suction-side pressure drops too low — protecting the compressor from running on a leaking or undercharged system that would otherwise cause overheating and coil freeze-up.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eOEM Part Number: 0130M00075\u003c\/li\u003e\n\u003cli\u003eFits Model: APH1543M41AB (3.5-ton, 15 SEER packaged heat pump)\u003c\/li\u003e\n\u003cli\u003eFunction: Low-side pressure limit (auto-reset)\u003c\/li\u003e\n\u003cli\u003eContacts: Normally closed, opens on falling pressure\u003c\/li\u003e\n\u003cli\u003eConnection: 1\/4\" SAE quick-connect fitting with Schrader depressor\u003c\/li\u003e\n\u003cli\u003eWiring: Push-on 1\/4\" spade terminals\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eGoodman calibrates this switch to the precise cut-out\/cut-in pressures the APH1543 platform expects. Aftermarket substitutes often trip early on cold mornings or fail to detect a slow leak, leading to false lockouts or unprotected compressor operation.

Kill power, label the two low-voltage leads, thread on the new switch, and reconnect. Budget 20–30 minutes. When no sealing port is present, refrigerant recovery is required — call a licensed technician.\u003c\/p\u003e","brand":"Goodman","offers":[{"title":"Default Title","offer_id":63058288738675,"sku":"GOODMAN-15622","price":22.95,"currency_code":"USD","in_stock":true}],"url":"https:\/\/nationalhvacparts.com\/products\/oem-goodman-low-pressure-cut-off-switch-for-aph1543m41ab-0130m00075","provider":"National HVAC Parts","version":"1.0","type":"link"}
