Halfway up, the door lets go of the opener with a clunk and sinks back to the floor while the trolley carries on to the top alone. It has happened three times this month, and each time the release lever is found half-cocked.
There are two releases on many garages, and this service covers both. Inside, the red handle drops from the trolley and anyone standing in the garage can pull it. Outside, some doors carry a small keyed cylinder, near the top on a sectional door or at mid-height on others; turning the key pulls a cable that throws the same lever from the driveway, which matters when the garage has no other door and the opener is quiet. Repair inside usually means a new cord, handle, lever or trolley. Repair outside means a new cylinder, cable or keys, routed clear of the section joints so the key turn reaches the lever.

Scene 1
With the door settled, the release is inspected link by link rather than as a single handle. The cord: frayed, knotted, sun-rotted or cut short. The handle: present, red, and the right shape to grip. The lever on the trolley: does it swing fully to the release position and snap back, or is it bent, sticky or missing its spring. The trolley and carriage: are the latch surfaces worn, is the body cracked, is the arm to the door straight. The stops at either end of the rail: has the trolley been driven into one. Each link is checked so the repair replaces what failed rather than the part nearest to hand.
Scene 2
A trolley jammed against the stop at the end of the rail is freed rather than forced. The release is pulled so the door is out of the picture, the chain or belt tension nut is backed off a few turns to give the trolley room, and the motor is run so the trolley walks away from the stop. The travel limit that let it run too far is then adjusted, the chain or belt is re-tensioned to the sag the maker specifies for that rail, and the trolley is reconnected. Because the limits were touched, the door is cycled and the reversal tests are repeated before the job is called done.
Scene 3
Before leaving, the technician walks through the release with you rather than describing it. Door closed. Pull the handle straight down until the lever clicks over. Lift the door by its handle or a gripping point on the panel face, never at the joint between sections. Lower it the same way. To reconnect, pull the cord toward the opener, or simply run the opener, and listen for the trolley to click onto the carriage. Anyone in the house who might face a blackout with the car inside is welcome to try it while the technician is there.

It covers most outages: the battery opens and closes the door on stored power, so the release stays on its hook. It is a wearing part that needs replacing every few years, and a status light or beep tells you when. The release is still the fallback for a flat battery or an opener that has itself failed, which is why the two are checked together. Many households on outage-prone streets keep both in working order.
Salt spray and meltwater get into the keyway during a thaw and freeze overnight, the same way they do in a house lock. Keep the cylinder face clear of slush, give it a puff of dry lock lubricant before the cold sets in, and carry a small de-icer through the winter. A weather cap over the cylinder helps on a door that faces the road. The technician cleans and treats the cylinder as part of any outside release repair.
Three usual causes. On many rails, pulling the cord back toward the opener deliberately holds the lever out for a spell of manual use, and someone forgot to return it. Or the trolley latch teeth or the release arm are worn or bent, so the two parts pass without catching. Or the carriage sits at the wrong point for the powered trolley to meet, since reconnecting is meant to happen during an opener cycle, not by pushing the door shut by hand. Each is a short fix once identified.
