Liftmaster Garage Door Excessive Closing Force Detected

Understanding Excessive Closing Force Detection

The excessive closing force detection feature is designed to prevent accidents and protect individuals and property from potential harm. It monitors the force exerted by the garage door when closing and activates safety measures if the force exceeds a specified limit. By detecting excessive force, Liftmaster ensures that the door stops and reverses to prevent damage or injury.

Potential Causes of Excessive Closing Force Detected

  1. Misaligned Safety Sensors: Misaligned safety sensors can trigger the excessive closing force detection mechanism. When the sensors aren’t properly aligned or obstructed, the system assumes an obstacle is present and activates the safety measures.
  2. Incorrect Force Setting: The force setting on your Liftmaster garage door opener may be set too high. This can lead to false detections of excessive closing force. Adjusting the force setting can help resolve this issue.
  3. Damaged or Worn Components: Over time, various components of the garage door system may become damaged or worn out. Malfunctioning springs, cables, or rollers can cause increased resistance, triggering the excessive closing force detection feature.
