Overhead Door opener codes

About Overhead Door codes

Overhead Door openers (Legacy and Odyssey lines) report problems through red and green LED patterns on the powerhead. Count the blinks of the color that is lit and match them to the table. The codes apply to model numbers such as Legacy 850 and Legacy 920; check the label on your unit to confirm yours.
