Chamberlain Garage Door Opener · Error code 1-3

What 1-3 Means

The wall control reports a stuck button or open circuit. Typically the lock or light button on the multifunction console is mechanically jammed.

Symptoms

  • 1 flash then 3 flashes
  • Opener ignores wall button presses
  • Door light may stay on

Common Causes

1
Stuck lock or light button

Mechanical button stuck in pressed position.

2
Failed wall control PCB

Internal switch contacts welded.

3
Broken wall wire run

Open circuit between head unit and wall control.

How to Fix It

  1. Press the lock and light buttons on the wall control to free any stuck button.
  2. Disconnect the wall control wires from the motor head. If 1-3 clears, the wall control is at fault.
