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. Genie counts blinks on its LEDs; the number of blinks, not their speed, identifies the fault.

Genie, from The Overhead Door Corporation, signals faults by blinking LEDs on the motor head and by wall-console diagnostics. Genie blink counts differ from LiftMaster, so do not use a LiftMaster chart for a Genie opener. The codes apply to model numbers such as H8000 and ISD990; check the label on your unit to confirm yours.
