Quick Guide from the Manual

This document provides instructions for replacing the logic board on your Chamberlain garage door opener. Important: Before beginning, disconnect all electric and battery power.

Always wear protective gloves and eye protection when working near the battery compartment.

Logic Board Replacement

1. Disconnect power and open the front panel.
2. Remove the battery cover and disconnect the battery.
3. Disconnect all wires from the logic board (safety reversing sensors, door control, door lock, and cable tension monitor).
4. Remove the logic board cover and disconnect all wiring harnesses.
5. Remove the four screws securing the logic board and discard the old board.
6. Install the new logic board and connect the wiring harnesses. Route the antenna through the channel in the new battery cover.
7. Adhere the new myQ serial number label over the original label on the logic board cover.

Door Profile Adjustment

You must set the door profile based on your garage door type and drum size to ensure proper operation.

• Door Profile 1: Standard to Heavy Weight Door with 4" drum (Recommended).
• Door Profile 2: Light Weight Door with 4" drum.
• Door Profile 3: Heavy Weight Door with 6" drum.
• Door Profile 4: Light Weight Door with 6" drum.
• Door Profile 5: High Lift or Vertical Lift Door (Tapered drum).

To set the profile: Press and hold the black button for one second until the UP and DOWN buttons turn solid. Use the UP and DOWN buttons to change the setting; the Learn LED will blink to indicate the selected profile. Press the black button to save.

Programming Travel Limits

1. Press and hold the Adjustment Button until the UP button flashes or a beep is heard.
2. Press and hold the UP button until the door reaches the desired UP position.
3. Press and release the Adjustment Button; the opener lights will flash twice.

Automatic Force Setup

Once travel limits are set, the opener will automatically enter a force-sensing operation. The door will open and close automatically. The opener will beep three times to confirm successful completion. If you hear one long beep, the setup failed; restart from the Travel Limit programming step.

Safety Testing

Protector System: Open the door and place an obstruction in its path. Attempt to close the door with the remote. The door should not move more than an inch.
