About This Item

The Pentair Switch Membrane (42002-0029Z) is the OEM replacement switch membrane for the Sta-Rite Max-E-Therm pool heater control panel.

⚠️ IMPORTANT: HEATER COMPONENT — PROFESSIONAL SERVICE REQUIRED
Gas and electrical heater components must be serviced by a licensed pool professional or qualified HVAC technician. Do not attempt to service gas or high-voltage components without proper certification.

The switch membrane is the tactile overlay bonded to the heater's control panel face, translating button presses to the underlying control board. When the membrane deteriorates — through UV exposure, chemical contact, or general wear — buttons may become unresponsive or register false inputs, disrupting heater operation. Replacing the membrane restores reliable control input without requiring full control board replacement.

About Pentair Pool Products and Parts

Pentair is often considered the "gold standard" for pool professionals, and for good reason. Founded in 1966 (originally by five inventors making high-altitude balloons!), the company has evolved into the global leader in smart, sustainable water solutions. For the DIY homeowner, Pentair represents the intersection of rugged durability and silicon valley-tier technology. They pioneered the Variable Speed Pump revolution with the IntelliFlo®, saving American pool owners millions in energy costs. Today, their ecosystem focuses heavily on automation, allowing you to control your pump, heater, lights, and chemistry from a single app. While they are a favorite among professional builders, their "EC" (E-Commerce) line of equipment allows homeowners to access pro-grade technology with valid warranties for DIY installation.
