Installed on the low (suction) side of the refrigerant circuit, it opens the control circuit and stops the compressor when suction pressure drops too low — protecting against loss-of-charge, a restricted metering device, or freeze conditions. This prevents the compressor from running dry and slugging, which is a common cause of costly compressor failure.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003ePart type: Low-pressure (loss-of-charge) safety switch\u003c\/li\u003e\n\u003cli\u003eCircuit side: Low (suction) side\u003c\/li\u003e\n\u003cli\u003eFit: Goodman\/Amana WPH4324AMAB packaged unit\u003c\/li\u003e\n\u003cli\u003eFunction: Opens control circuit on low-side underpressure\u003c\/li\u003e\n\u003cli\u003eFactory-matched cut-out \/ cut-in pressure setpoints\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe \u003cstrong\u003eOEM 0130M00075\u003c\/strong\u003e uses the exact factory cut-out and cut-in setpoints tuned to this refrigerant system. Generic replacements with the wrong setpoints either lock out the compressor in cold weather or fail to protect against a genuine loss of charge.

Cut power to the unit, thread on the new switch, land the control leads on the correct terminals, and confirm normal suction pressures at startup with gauges.\u003c\/p\u003e","brand":"Goodman","offers":[{"title":"Default Title","offer_id":63058254594419,"sku":"GOODMAN-14859","price":22.95,"currency_code":"USD","in_stock":true}],"url":"https:\/\/nationalhvacparts.com\/products\/oem-goodman-low-pressure-switch-for-wph4324amab-0130m00075","provider":"National HVAC Parts","version":"1.0","type":"link"}
