This is the single most important verification step for this part. Once confirmed, check whether the membrane pad or the control board behind it is the source of your input failure: if all buttons are unresponsive while the display remains active, the membrane pad is the likely culprit. If the display is blank or showing fault codes unrelated to button input, have the control board evaluated before replacing the membrane pad.\u003c\/p\u003e\n\n\u003c!-- wft:processed:manual:2026-04-03 --\u003e","brand":"Pentair","offers":[{"title":"Default Title","offer_id":53912383258899,"sku":"472610Z","price":140.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0920\/0687\/5411\/files\/PEN472610Z_0.png?v=1772793779","url":"https:\/\/poolaroo.com\/products\/pentair_472610z","provider":"Poolaroo","version":"1.0","type":"link"}
