It has to confirm its condition before the sequence is allowed to continue, which is what stops the heater firing when something upstream is wrong.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhen to suspect it\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe pattern to look for is a heater that starts its sequence, gets partway, and then quits without producing heat. Plenty of faults look like that, but the pressure switch is one of the least expensive to replace, so it is worth eliminating before you move on to the costlier components.\u003c\/p\u003e","brand":"Pentair","offers":[{"title":"Default Title","offer_id":48628782006484,"sku":"PUR-151-4110","price":53.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/9568\/2516\/files\/default_b5bc97c3-d912-4e1c-8086-2929da9d65c6.jpg?v=1788750561","url":"https:\/\/www.activepoolsupply.com\/products\/minimax-nt-air-pressure-switch","provider":"Active Pool Supply","version":"1.0","type":"link"}
