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.


Short in the safety beam sensors


Safety beam sensors may be defective. Replace safety beam sensors to troubleshoot. If you have two identical garage door openers, remove the safety beam sensors from the other opener and add them to the non-working garage door opener to troubleshoot.

Short in the garage door opener circuit/logic board

Circuit/Logic board may be defective. Replace circuit board to troubleshoot. If you have two identical garage door openers, remove the circuit board from the other opener and add it to the non-working garage door opener to troubleshoot.

Short in the garage door opener receiver board


Receiver board may be defective. Replace receiver board (receiver board may be internal or external - internal means inside the powerhead - external is a separate box outside the powerhead) to troubleshoot. If you have two identical garage door openers, remove the receiver board from the other opener and add it to the non-working garage door opener to troubleshoot.

Short in the wiring from external receiver


Receiver board may be defective. Replace receiver board (receiver board may be internal or external - internal means inside the powerhead - external is a separate box outside the powerhead) to troubleshoot. If you have two identical garage door openers, remove the receiver board from the other opener and add it to the non-working garage door opener to troubleshoot.

Your remote is sending random signals (if defective or if the remote is becoming defective)

Remove battery from remote for a few days and see if problem continues. Replace remote if necessary.

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 its 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.
