1. Adjust the door closer

  1. Open the door using the handle.
  2. Check if the door is properly closed by checking if the green light is off. If the door is not properly closed, there may be something obstructing the door from closing completely, in which case you will need to remove the obstruction.
  3. If the door is properly closed, press and hold the button on the side of the door closer for 2 seconds.
  4. Release the button and wait for the door closer to reset.
  5. Close the door closer.
  6. If the error code persists, you may need to replace the door closer.

2. Check the door for obstructions

To check for obstructions in the door, you will need to remove any obstructions and then re-install the door. Once the door is re-installed, you can test the door to see if the excessive closing force error code is resolved.

3. Check the door alignment

  2. Look at the alignment of the side rails and the door panel. If there is an adjustment that needs to be made, make the adjustment.

  5. Check the alignment again. If there is still an adjustment that needs to be made, make the adjustment.
  6. Reinstall the door and close it.

4. Check the door hardware
