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.
