The opener should have a purple learn button and use a 315 MHz Security+ radio system.

A purple learn button alone does not guarantee compatibility. Before ordering, confirm that the number printed on the original logic board or listed in the opener’s replacement-parts diagram matches 041AS050-1 or one of its confirmed alternate numbers.

This board is not intended for openers using yellow, red, orange, green, or another learn-button system.

Common Symptoms of a Failing Logic Board

Replacement may be needed when the opener:

• Does not respond to compatible remotes or wireless keypads
• Operates unpredictably or intermittently
• Has visible burn marks or damaged electronic components
• Does not correctly process safety-sensor signals
• Has stopped working after an electrical surge
• Has power but does not operate correctly
• Has a damaged receiver or control circuit

These symptoms can also be caused by wiring, sensors, remotes, power supply problems, or other opener components. Proper diagnosis is recommended before replacing the board.

Programming After Installation

After replacing the logic board, existing remote controls, wireless keypads, and vehicle HomeLink systems may need to be programmed again using the purple learn button.

Package Contents

• One 315 MHz receiver logic board
• Attached end panel

Remote controls, wireless keypads, safety sensors, wiring, and additional opener components are not included unless specifically shown or stated.

Installation and Safety

Disconnect electrical power to the garage door opener before removing the housing or handling internal components. Photograph and label the existing wire connections before disconnecting the original board.

Logic boards contain sensitive electronic components that can be damaged by static electricity or incorrect wiring. Installation should be performed by a qualified garage door technician when the cause of the failure is uncertain.
