If your electric garage door malfunctions, an article on yahoo.com provides these troubleshooting tips to help you get to the root of the problem.

  • Make sure the opener is plugged in and switched on.
  • Pull the emergency release chain – if the door still won’t open, proceed to the next step.
  • Check the tracks – look for dirt, rocks or anything that could be blocking them.
  • Check the door – check the frame and panels for signs of impact or warping.
  • Cool the motor down – allow the motor to cool off, as it may have overheated.
  • Press the auxiliary button – if it doesn’t work, you may have a faulty controller.
  • Try the remote – if this doesn’t work, check the batteries, as they may be flat.
  • Change your security code – someone nearby may have accidentally pressed your code to try and open their own door.
  • Check the header and door bracket – look for any misalignment or looseness.
  • Check the drive belt – look for any looseness and tighten accordingly.
  • Check the safety sensitivity control – this may be malfunctioning if the door is reversing suddenly.
  • Check the height adjustment screws – these may need adjusting if the door only partially opens or closes.
