The MasterTemp line includes multiple BTU ratings and fuel configurations; blower kits are not interchangeable across models. If your heater is displaying an ignition fault or airflow fault code, inspect the blower for seized bearings or debris obstruction before condemning the component — a blocked intake can produce the same fault as a failed motor. Have a licensed technician verify the fault code against the MasterTemp service manual before replacing this blower.\u003c\/p\u003e\n\u003c!-- wft:processed:manual:2026-04-06 --\u003e","brand":"Pentair","offers":[{"title":"Default Title","offer_id":53971919536403,"sku":"460743","price":696.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0920\/0687\/5411\/files\/pentair-air-blower-kit-natural-gas-units-models-250na-mastertemp-460743-3.webp?v=1780914494","url":"https:\/\/poolaroo.com\/products\/pentairwaterpoolandspainc_460743","provider":"Poolaroo","version":"1.0","type":"link"}
