Craftsman Opener Error Code Yellow Learn LED rapid flash: Meaning and Fix
Also shown as: Yellow light flashing fast, Learn button LED flashing continuously
Reading the opener display
A garage door opener reports faults through blinking LEDs on the motor head, a diagnostic window on the logic board, or the wall control. Count the flashes slowly and repeat the count before you decide what you saw. Craftsman openers follow the Chamberlain flash chart.
Craftsman garage door openers are made by the Chamberlain Group under license, so they share the LiftMaster and Chamberlain diagnostic codes. Look for a model number starting with 139. on the label. Check the model label on your unit before using any chart.
What causes Yellow Learn LED rapid flash
- A remote, mini-remote or visor clip with a button wedged down by a seat, keys or a bent case
- A wall control with a shorted pushbutton
- A weak or leaking coin cell that makes the control transmit constantly
- A wireless keypad with a swollen battery or a sticky key
How to fix it
- Pull the battery out of each remote and the keypad one at a time, and watch the yellow LED after each removal.
- When the flashing stops, you have found the device that was transmitting; clean around the button or swap its battery.
- If it starts flashing again with fresh batteries, replace that remote or keypad and re-learn it with the Learn button.
- Check the wall control wiring for a pinched wire if the flashing continues with every wireless device unpowered.
- Unplug the opener for 30 seconds and power it back on to clear the fault memory.

Questions
Why is the yellow light on my Craftsman opener flashing quickly?
The opener is hearing a continuous signal from a paired remote or keypad whose button is stuck. Pull batteries one device at a time to find it.
Can a stuck button drain my car remote battery?
Yes. A button held down transmits constantly, which kills a coin cell in days instead of years.
Do I need a new logic board?
Rarely. The cause is nearly always a remote or keypad, not the board.
