Short in the safety beam sensor wiring

 Replace wiring to safety beam sensors to troubleshoot. Upgrade from 22 guage wiring to 16 guage. Cold temperatures can affect the wiring and cause a short. Lower guage wiring is thicker. Check for pinches, frays, or cuts in the wiring that can also short the wiring. Stapling the wiring is a common cause for shorts because it cuts through the plastic coat of the wiring and shorts the system.

Garage Door Opening On It's Own Tips:

  • Unplug the garage door opener when you leave for work everyday if it is opening on its own.
  • Unplug the garage door opener when you leave for vacation.
  • Do not leave batteries in spare or defective remotes because they can short and send signals to open the garage door.
  • Do not share your keypad access code with neighbors, if you do, change the access code to prevent them from opening your garage door when you are not there.
  • Unplug the garage door opener while you sleep if you are still troubleshooting the problems of it opening on it's own. Prevents burglary while you and your loved ones are sleeping. Prevents pets from escaping.
  • Add a Heavy Duty Appliance Module to control the electrical outlet by remote before using the actual remote for the garage door opener as an added layer of security to the biggest door of your house. (See X10 PRO Tip)
 X10 PRO TIP: Added layer of security for your automatic garage door opener:

PAO11 replaces existing outlet for garage door opener, garage door plugs into "Controlled" half of PAO11. Set house & unit code other than A1. PAT01 plugs in "hot" half of outlet. Set house code to match PAO11. PHR03, PHR04 or properly programmed Home Link system will power outlet before garage door remote will work.
