My garage door opener opens on it own.


hi, this seems like a relay problem. internal relays in the control unit can get old and start connecting and disconnecting automatically causing the garage to open randomly. especially if you are in a high humidity climate.

You can either replace the control unit or send it to an electronics repair shop to replace the relays inside the control unit for you.

The most common cause of this problem is a bad wall control the wiring going to it. You can eliminate both temporarily by removing the wire at terminal 1 on the back of the motor unit. The wiring sometimes is shorted by the staples the installer uses. The wall control gets used a lot.
