LiftMaster 41A5021-1HATS 390 MHz Receiver Logic Board for ATS211X and ATS211R

The LiftMaster 41A5021-1HATS is a genuine replacement receiver logic board assembly for select LiftMaster ATS garage door operators using the 390 MHz Security+ radio system.

This board controls the operator’s primary electronic functions, including remote-control reception, wall-control communication, safety-sensor input, and normal opening and closing commands.

It is designed for compatible ATS211X and ATS211R operators equipped with a red or orange Learn button. Because several LiftMaster boards use similar 41A5021 part numbers, verify the complete number, radio frequency, Learn-button color, and connector layout before ordering.

How It Works

The receiver logic board acts as the main electronic control center inside the garage door operator. It processes signals from compatible remote controls, the wired wall control, safety-reversing sensors, and the operator’s internal components.

The integrated 390 MHz receiver uses Security+ rolling-code technology. After installation, compatible remote controls and wireless keypads must be programmed to the replacement board using the red or orange Learn button.

Installation Requirements

Disconnect electrical power from the operator before removing the cover or handling internal electronic components.

Photograph or label all existing wire and connector locations before removing the original board. Transfer each connection carefully to the corresponding terminal or connector on the replacement board.

After installation, compatible remote controls and wireless keypads must be reprogrammed. Travel limits, force settings, and safety systems may also require testing or adjustment.

Installation & Safety

Garage door operator repairs involve electrical components and moving mechanical equipment. Professional installation is recommended when the source of the failure has not been properly diagnosed.

Before replacing the board, inspect the operator for damaged wiring, loose connectors, moisture, corrosion, power-surge damage, safety-sensor problems, and other conditions that may have caused the original failure.

After installation, test the wall control, remote controls, safety-reversing sensors, travel limits, force settings, and automatic reversal system before returning the operator to service.
