An opener that stops working has failed in one of four layers, power, logic, drive or the door itself, and checking them in that order finds the culprit in minutes instead of guessing at parts.

No lights, no sounds, no response: outlet first. Plug a lamp into the opener outlet; garage GFCIs trip constantly and the reset button may be on a different outlet in the chain. Power confirmed, look for status LEDs; most brands blink error codes that decode in the manual or on our decoder pages for LiftMaster, Chamberlain and Genie.
A rapid click with no motor movement often points to a failed start capacitor or a logic board fault. Capacitors are a cheap, common repair on chain and belt units.
Motor runs, door ignores it: the drive is broken. On chain and belt units the classic failure is a stripped main gear, white plastic shavings inside the housing confirm it, and a gear kit is far cheaper than a new opener. On screw drives, worn couplers do the same. A snapped trolley shows up as the traveler moving without the door.
Pull the red cord with the door closed and lift by hand. Heavy, crooked or grinding means the door itself is the patient: spring, cables or track. An opener forced to drag an unbalanced door strips gears and burns out early, so fixing the door first also saves the opener. Balance and spring work live on our spring page.
Want a number, not a sales pitch? Call 757-208-1600 and we quote it on the phone where we can.
On a unit under roughly ten years old with a sound motor, usually yes; a gear kit runs far below replacement. Older than 15 years, the math flips because of missing safety and security features.
Lock mode engaged on the wall console, dead remote batteries, or lost remote pairing. Re-pair per the learn button under the opener light cover; it takes seconds.
No, that is the photo-eye safety system vetoing the close. Align the sensors until both LEDs are steady and the door will close normally.
If the failed part is generic, capacitor, gear kit, trolley, yes. When boards or rails are unobtainable we say so and quote a replacement with the labor priced in the open. Details on the opener service page.
