The troubleshooting steps to follow if your automatic garage door refuses to open.

  • Check the plug – make sure the cord is plugged in and the power is turned on.
  • Make sure it’s not locked – many doors have a lock feature, which may have been inadvertently activated.
  • Turn it off and on again – sometimes the sensors need resetting and this will often do the trick.
  • Check the batteries – inspect and replace the batteries in your remote if they are flat.
  • Reprogram the remote – resetting your remote may fix the problem if it has become re-programmed.
  • Check the sensor – make sure it is plugged in and clean the ‘eye’, as it may have dust on it.
  • Check the chain – a broken or loose chain could cause the problem. If it is broken, you will need to have a new one fitted.
  • If all these steps fail to fix the problem, pull the red release cord, so that you can at least open and close the door manually, until a professional repairer can be contacted.
