It is the genuine Jandy replacement part.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat it protects\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eA heat pump moves heat by circulating refrigerant, and the compressor lives on the high pressure side of that loop. If pressure there climbs past the design limit, the compressor is at risk. The high pressure switch is a simple safety device that opens the control circuit when that happens, shutting the unit down before the expensive part is damaged.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDiagnosing before you replace\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eA heat pump repeatedly faulting on high pressure has two possible causes: the switch has failed and is opening when it should not, or the pressure really is high. Genuinely high head pressure comes from a dirty or blocked coil, a fan not moving air properly, or poor water flow through the heat exchanger. Check those first. Replacing a switch that was doing its job correctly just removes the protection and leaves the underlying fault in place.\u003c\/p\u003e","brand":"Jandy","offers":[{"title":"Default Title","offer_id":48634156351700,"sku":"AEH-151-1141","price":65.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/9568\/2516\/files\/default_42a66d6d-d005-4faf-8fff-1dd79cf799ef.png?v=1788825962","url":"https:\/\/www.activepoolsupply.com\/products\/zodiac-r0575400-high-pressure-switch-for-je-heat-pump","provider":"Active Pool Supply","version":"1.0","type":"link"}
