Causes of the “Excessive Closing Force Detected” Issue

  1. Misaligned Safety Sensors: Chamberlain garage door openers have safety sensors situated near the floor on each side of the garage door. If these sensors are misaligned, the system might mistakenly detect an obstruction, triggering the safety feature and stopping the closing process.
  2. Dirty or Obstructed Sensors: Dust, dirt, or debris on the safety sensors can interfere with their proper functioning. This interference may lead to inaccurate readings and the erroneous triggering of the “Excessive Closing Force Detected” message.
  3. Damaged Garage Door Tracks: Bent or damaged tracks can cause the garage door to veer off its path, leading to increased resistance when closing. The opener’s sensors will detect this resistance and activate the safety feature.
  4. Broken Garage Door Springs: Garage door springs counterbalance and ease opening/closing. A broken or tensionless spring can make the garage door heavy and trigger the safety feature.

Troubleshooting and Solutions

  1. Check Sensor Alignment: Start by inspecting the alignment of the safety sensors. Ensure they directly face each other and have no obstructions. Adjust their positions if necessary, and clean the sensors to remove any dirt or debris.
  2. Inspect Garage Door Tracks: Examine the garage door tracks for any signs of damage or misalignment. If you notice any issues, consider contacting a professional garage door technician to make the necessary repairs.
  3. Test the Garage Door Springs: Regularly inspect garage door springs to identify signs of wear and tear. If you suspect a broken or faulty spring, it’s best to seek professional assistance as handling springs can be dangerous.
  4. Check Opener Settings: Some Chamberlain garage door openers have adjustable force settings. Ensure you appropriately set the closing force according to the manufacturer’s guidelines. Adjust the settings if necessary to avoid excessive force.
