Steady Yellow Antenna LED — Chamberlain Garage Door Opener Yellow Antenna LED — Constant Signal or Learn Mode

The yellow LED next to the antenna/Learn button reports two different things depending on how it behaves. If it is flashing rapidly or continuously, the opener is receiving a constant radio signal — usually a remote with a button stuck down. If it is simply steady/solid because you just pressed the Learn button, that means the opener is in Learn/programming mode, waiting for a remote press to pair. Neither behavior means no remote is paired or that memory was cleared.

How to fix it

  1. If the LED is flashing on its own (you did not just press Learn) and the door is moving or reversing unexpectedly, suspect a stuck remote.
  2. Gather every remote paired to this opener and remove the battery from each one, one at a time, checking after each removal whether the flashing stops.
  3. Once you isolate the stuck remote, replace its battery, or replace the remote if a button is physically stuck or damaged.
  4. If the LED is steady only because you just pressed the Learn button, that is normal — press the button on the remote or keypad you want to pair within 30 seconds, or let the opener time out of Learn mode on its own.

Why it happens

Typical signs: Yellow LED near the Learn button flashing rapidly or continuously (not from pressing Learn) · Door opens, closes, or reverses on its own · LED goes solid yellow for about 30 seconds right after pressing the Learn button (normal)

  • Stuck remote control button A remote lodged in a pocket, console, or under something with a button pressed transmits continuously, which the opener reads as a constant signal.
  • Learn/programming mode active Pressing the Learn button lights the LED steady for about 30 seconds while the opener waits to pair a remote or keypad — this is expected, not a fault.
