Decoding the Blinking Patterns of Your Chamberlain Garage Door Opener

When your Chamberlain garage door opener blinks 2 times, it’s trying to communicate a specific message about the state of your garage door system. Understanding these blinking patterns can help you diagnose potential problems more effectively. Here are some common reasons why your Chamberlain garage door opener blinks 2 times:

  1. Sensor Misalignment: The blinking pattern may indicate that the safety sensors installed on either side of your garage door are misaligned or obstructed. These sensors are designed to detect objects in the door’s path and prevent accidents. If they’re not properly aligned, your Chamberlain opener may blink 2 times to alert you to the issue.
  2. Obstruction Detection: The sensors in your Chamberlain garage door opener actively detect if there’s an obstruction preventing the door from closing properly. If the sensors detect an obstacle, the opener may blink 2 times to indicate that it’s unable to close the door safely.
  3. Lack of Power: In some cases, a blinking light on your Chamberlain garage door opener could signal a power-related issue. If the opener is not receiving sufficient power or if there’s a problem with the electrical connection, it may blink 2 times to alert you to the problem.
