Product Overview

The Pentair 461106 6-Button Membrane Pad Kit is a genuine OEM replacement keypad designed for compatible Pentair MasterTemp® and Sta-Rite Max-E-Therm® pool and spa heaters. The membrane pad serves as the heater’s user interface, allowing the operator to select operating modes, adjust temperature settings, and control heater functions.

This replacement is ideal when the existing keypad is cracked, faded, peeling, difficult to press, or no longer responding consistently. Installing a new membrane pad can restore normal control-panel operation without replacing the complete heater or control assembly.

Part number 461106 is commonly associated with newer heater configurations equipped with the updated six-button control interface and RS-485-compatible electronics. Heater production dates, control boards, and keypad configurations can vary, so the existing part number and control-panel layout should always be verified before ordering.

Benefits

A damaged membrane pad can make it difficult or impossible to adjust the heater temperature or select the correct pool and spa operating modes. Replacing the keypad restores a clean, responsive interface while maintaining the original appearance of the heater.

Because this is a genuine Pentair replacement component, it is manufactured to fit compatible heater control-panel recesses and connect to the appropriate control board. The sealed membrane design also helps protect the keypad area from routine outdoor exposure when installed correctly.

Specifications

Compatibility

The Pentair 461106 membrane pad is designed for compatible heater models using the newer six-button control-panel arrangement. It is commonly referenced for updated MasterTemp and Max-E-Therm heater configurations produced after the heater control-system transition in 2021. Compatibility should not be determined by heater BTU rating alone.

Compatible heater families may include:

• Pentair MasterTemp pool and spa heaters
• Sta-Rite Max-E-Therm pool and spa heaters
• Select newer heaters using an RS-485-compatible control board
• Select Pentair ETi heater applications when specifically identified in the applicable parts diagram

This keypad may not replace older membrane pads with a different number of buttons, connector design, button layout, or control-board configuration.

Installation Information

Disconnect all electrical power and gas service to the heater before beginning installation. The heater control-panel assembly must be opened to access the membrane-pad connection on the control board.

The existing membrane is removed from the top panel, and the replacement membrane connector is routed through the control-panel opening. The adhesive backing is then removed, and the new keypad is carefully aligned and pressed into the recessed control-panel area.

Pentair’s service instructions state that heater control components should be installed and serviced by a qualified pool professional. Incorrect installation can damage the keypad, connector, control board, or heater wiring.

Confirm Before Ordering

Before purchasing, verify:

• The heater is a Pentair MasterTemp or Sta-Rite Max-E-Therm model.
• The existing keypad has the same six-button layout.
• The current membrane pad or parts diagram identifies part number 461106.
• The heater uses the compatible updated control-board configuration.
• The membrane pad is the failed component and not the control board, wiring harness, temperature sensor, or display.
• The connector and control-panel shape match the replacement part.

Providing the heater model number, serial number, manufacturing date, and a photo of the existing control panel is recommended when compatibility is uncertain.

Warranty Information

This product is covered by the applicable Pentair manufacturer’s limited warranty against qualifying defects in materials or workmanship. Warranty coverage does not include damage caused by improper installation, incorrect wiring, moisture intrusion, chemical exposure, misuse, unauthorized modification, or failure of another heater component.

Professional installation and proof of purchase may be required for warranty consideration.

Customer Q&A

Does this kit include the heater control board?
No. Part number 461106 is the membrane keypad kit. A control board, display assembly, wiring harness, and complete heater are not included.

Will this fit every Pentair MasterTemp heater?
No. MasterTemp heaters have used different control-panel and membrane configurations. Confirm the heater’s production date, existing keypad layout, and required part number before ordering.

What are the signs of a failing membrane pad?
Common symptoms include buttons that must be pressed repeatedly, buttons that do not respond, a cracked or peeling keypad surface, faded labels, or individual heater functions that cannot be selected.

Can a bad control board cause similar symptoms?
Yes. A failed control board, damaged ribbon connection, wiring issue, or power problem can produce symptoms similar to a defective keypad. Proper diagnosis is recommended before replacing parts.
