The garage door opener is compatible with myQ® accessories such as the G828LG Internet Gateway, 041A7928-3 myQ® Control Panel, and 041A6287 Remote Light. These accessories enable remote monitoring and control of the garage door and associated lighting.
Mounting the Door Control
Mounting the door control is a critical step in the installation process. The following instructions are adapted from the manufacturer’s manual and should be followed carefully to ensure proper alignment and functionality:
Positioning the Mounting Bracket:
- Place the mounting bracket against the wall with curved arms facing the door. Ensure there is sufficient clearance for the sensor beam to remain unobstructed.
- If additional depth is required, use an extension bracket (Model 041A5281-1) or wood blocks. These are available in the Accessories section of the manual.
Drilling Pilot Holes:
- Use the bracket mounting holes as a template to locate and drill two 3/16" diameter pilot holes on the wall at each side of the door. The holes should be no higher than 6" (15 cm) above the floor.
- If using extension brackets or wood blocks, adjust the right and left assemblies to the same distance out from the mounting surface. Ensure all door hardware obstructions are cleared.
Attaching the Bracket:
- Attach the brackets to the wall using lag screws (not provided). If the installation requires floor mounting, use wood blocks or extension brackets to elevate the sensor brackets so the lenses are no higher than 6" (15 cm) above the floor.
Aligning the Sensors:
- Slide a 1/4"-20x1/2" carriage bolt head into the slot on each sensor.
- Carefully measure and place the right and left assemblies at the same distance from the wall. Ensure that all door hardware obstructions are cleared.
- Fasten the brackets to the floor using concrete anchors as shown in the diagram.
Connecting the Power and Wires
Proper electrical connections are essential for the safe and efficient operation of the Chamberlain B2401T. The following steps outline the process for connecting the power cord and internal wiring:
Preparing the Power Cord:
- Remove the garage door opener from the torsion bar and set the cover aside.
- Cut the line cord 6" (15.2 cm) above the strain relief.
- Squeeze the strain relief and push it into the garage door opener, then remove the strain relief from the line cord.
Installing the Conduit Adapter:
- Install a 90° conduit (not provided) or flex cable adapter (not provided) to the 7/8" hole. Reinstall the garage door opener to the torsion bar.
Running and Stripping Wires:
- Run the wires through the conduit, cutting them to the proper length. Strip the insulation from the wires as follows:
- 1/2" (1.3 cm) from the existing black, white, and green wires.
- Connect the line to the black wire and neutral to the white wire using wire nuts (not provided).
- Connect the ground wire to the green ground screw.
- Run the wires through the conduit, cutting them to the proper length. Strip the insulation from the wires as follows:
Securing Wires:
- Properly secure the wires under plastic ties to ensure they do not come into contact with moving parts.
- Reinstall the cover and ensure all connections are tight and secure.
Safety Precautions for Electrical Work
The manual emphasizes several critical safety precautions to prevent injury or equipment damage:
- Power Disconnection: Always ensure the power is disconnected before removing the cover and establishing any wiring connections.
- Electrical Code Compliance: The installation and wiring must comply with all local electrical and building codes.
- No Extension Cords: Avoid using extension cords, 2-wire adapters, or any modifications to the plug. Ensure the opener is properly grounded.
Failure to follow these precautions may result in serious injury, electrocution, or fire. Users are advised to consult a trained technician for advanced or customized adjustments.
Setting Up the Internet Gateway and myQ® App
To enable remote access and control, the Chamberlain B2401T must be connected to the myQ® ecosystem using the G828LG Internet Gateway and the myQ® app. The following steps outline the setup process:
Connecting the Internet Gateway:
- Connect the Internet Gateway to the router and power supply.

Downloading and Configuring the myQ® App:
- Download the myQ® app from the App Store or Google Play.
- Create an account or log in with an existing one.
- Follow the on-screen instructions to locate and connect the Internet Gateway.
Adding the Garage Door Opener:
- Select the device you wish to add (Garage Door Opener).
- Within three minutes of selecting the opener in the app, press the LEARN button two times on the myQ® control panel. The red LEARN LED will turn on.
- When the red LEARN LED turns off, the programming is complete. The opener will appear in the device list.
- Name the device (e.g., "Garage Door Opener") for easy identification.
Troubleshooting Connection Issues
If the myQ® control panel cannot be added to the Internet Gateway, the user is advised to erase all codes from the door control and try again. This will require reprogramming any accessories that were previously used.

- Position the bottom hole of the door control over the screw and slide down into place. Attach the top screw.
Adjusting the Limit Settings:
- The garage door opener must be calibrated to ensure it stops at the correct open and closed positions.
- Use the limit adjustment settings to fine-tune the travel distance based on the door’s weight and track length.
Verifying Safety Sensors:
- The door will not close unless the Protector System® and cable tension monitor are connected and properly aligned.
- Periodic checks are required to ensure the sensors are functioning correctly and the door operates safely.
