Chamberlain Opener Error Code 1-5: Meaning and Fix
Also shown as: 15, Up 1 Down 5
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. Chamberlain boards use the same flash chart as LiftMaster; the Learn button color matters.
Chamberlain makes the openers sold at home centers and shares its logic boards and diagnostic code tables with LiftMaster and Craftsman. The faults show as a flash count on the Learn LED or the motor-head display. The codes apply to model numbers such as B4505T and B2212T; check the label on your unit to confirm yours.
What causes 1-5
- A door that is binding or a spring that has broken so the motor cannot turn
- A loose or damaged travel module cable
- A trolley caught on a stop or a worn drive gear
- A failed RPM sensor or travel module
How to fix it
- Pull the emergency release and move the door by hand; it should travel smoothly.
- Fix any binding, bent track or broken spring first (spring work is a pro task).
- Reseat the travel module cable at the board and module.
- Unplug the opener for 30 seconds and retest.
- Replace the travel module if the code returns with a free-moving door.

Yes, because the motor cannot turn a door it cannot lift.

A travel module kit is a moderate part; labor depends on the model.
