Spring type
Torsion vs extension, wire size and cycle rating.
01Common opener problems
Misaligned or dirty safety sensors, stripped drive gears, worn trolley carriages, dead remotes, travel limits drifting out of adjustment and failed logic boards. Power outages and storms can also damage boards.
02Repair or replace
Older openers without rolling code security or battery backup may be worth replacing. Belt drives are quieter for garages under bedrooms; chain drives are durable; wall-mount jackshaft units free up ceiling space.
03Check the door first
An opener cannot fix a heavy, unbalanced door. If springs are worn, fix them first with garage door spring repair.
