The control watches it and holds the unit off until the switch confirms that pressure is in range. That protects the equipment from running under conditions it should not run in, and it is why a failed switch presents as a unit that simply will not start.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eBefore you order\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eHayward uses more than one pressure switch across its heating products. Pull the old one, read the number on it, and confirm it is CHXPRS1931 rather than ordering from the model name alone.\u003c\/p\u003e","brand":"Hayward","offers":[{"title":"Default Title","offer_id":48634285981908,"sku":"HAY-151-1460","price":78.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/9568\/2516\/files\/default_5bc9bdc3-cae5-42b5-b706-c0ab9421f63f.png?v=1788828189","url":"https:\/\/www.activepoolsupply.com\/products\/pressure-switch-cz-model","provider":"Active Pool Supply","version":"1.0","type":"link"}
