The motor runs but the door stays still
Stripped drive gear, disengaged trolley, or a chain or belt off its sprocket. Usually a same-visit repair — and the balance gets checked to find out why it stripped.

Opener Repair in Darrenwood
Darrenwood is a quiet residential suburb of family homes on regular stands in the western Randburg area. Doors that have accumulated repairs from several different people over the years, which usually means the motor's force setting has been raised more than once.
That is the context garage door opener repair in Darrenwood happens in. A lot of the units in this area are older motors retro-fitted to doors that pre-date them. That combination produces a very specific fault pattern — stripped gears and cooked capacitors — because the motor has spent years lifting more door than it was sized for.
This page covers what that means in practice — the faults we actually attend here, how the job is diagnosed and priced, and how quickly a technician reaches Darrenwood. For the subject in full, see our garage door opener repair guide; for everything else we do here, see garage door services in Darrenwood.
Own technicians, parts on the van, and a 12-month workmanship warranty in writing.
Scope of work
The unit is tested as a system: supply, board, motor, gearbox, sensors and stored settings. Most faults are a single component on a board that is otherwise fine, and replacing that component is a fraction of the cost of a new motor.
The doors here have usually had several owners and several repairers, and the history matters. A force setting that was turned up years ago to mask a dragging roller is still turned up, and the door has been pushing through the problem ever since.
Everything is quoted as a fixed price on site before work starts, and every repair and installation in Darrenwood carries the same 12-month workmanship warranty as the rest of the footprint.
Real situations
These are the calls we take most often from Darrenwood and the surrounding Randburg area.
Stripped drive gear, disengaged trolley, or a chain or belt off its sprocket. Usually a same-visit repair — and the balance gets checked to find out why it stripped.
Almost always the safety beams — filmed lenses, a knocked bracket or a loose terminal. The cheapest fault on this list, and the one most often mistaken for a dying motor.
Flattened backup battery, tripped supply, blown fuse or a surge-damaged board. Tested in that order. Most cases end at the battery, not the board.
The opener has detected an obstruction: blocked beams, a low limit setting, or genuine mechanical resistance. Clean the beam lenses first. If that is not it, do not turn the force up — find the cause.
Opener faults
This is the most common opener fault and it has three usual causes. The nylon drive gear inside the head unit has stripped its teeth, so the motor spins against nothing. The trolley has been left disengaged after someone used the manual release. Or the chain or belt has jumped its sprocket.
All three are inexpensive repairs and all three are usually finished in one visit. A stripped gear is also a symptom worth reading: gears strip because the motor has been fighting a heavy or badly balanced door, so the balance gets checked before the new gear goes in.
A significant share of "the motor is broken" call-outs end with the motor untouched. A broken torsion spring makes the door too heavy for the opener to lift, so it strains, trips its overload and stops. A slipped cable makes the door bind in the tracks, and the opener reverses out of it.
In both cases the opener is behaving exactly as designed — refusing to force a door that is not moving freely. Replacing it would achieve nothing except destroying a second motor.
Behaviour that changes day to day is nearly always either the safety beams or a board on its way out. Beams are the cheaper and far more common answer: a lens that has filmed over, a bracket knocked by a bicycle, a spider building across the sensor, or a wire that has worked loose in the terminal.
A door that refuses to close and flashes an error code on the head unit is telling you exactly this. Most units blink a count that maps to a specific fault, and reading it saves a great deal of guessing.

How it works
The same order on every job, whether it is a single household door or a run of doors in one complex.
Manual release, balance test by hand — before the opener is blamed for anything.
Error codes off the head unit, supply and fuse checked, battery load-tested.
Capacitor, motor, gearbox, drive, limit switches and safety beams tested in turn.
Repair priced against replacement where the unit's age makes that a real question.
Component replaced, travel limits reset, force set to the minimum that works.
Auto-reverse tested against an obstruction and the beams realigned and cleaned.
Coverage
Darrenwood is a short run from our Sandton base, so emergency call-outs are typically attended within 20 minutes and standard bookings are same or next working day.
A fair number of doors in this area were built to be opened by hand and automated long afterwards. The motor is then doing the springs' work on every cycle, which is why the balance test comes first here even when the call was about the motor.
The same run covers Randburg, Northcliff, Blairgowrie and Parkhurst, so a technician already working nearby can often be routed to Darrenwood the same day. If your suburb is not listed, it is worth calling — the Randburg service area extends beyond the pages published so far.
Anything that leaves a property unsecured is dispatched ahead of standard bookings at any hour — see emergency garage door service.

FAQ
Yes. Centurion, Digidoor, Chamberlain, Gliderol and ET units are all repaired in Darrenwood as part of our Randburg coverage, with common capacitors, gears, limit switches and batteries carried on the van. Darrenwood is a short run from our Sandton base, so emergency call-outs are typically attended within 20 minutes and standard bookings are same or next working day.
Usually, and usually cheaply. The common causes in Darrenwood are a flattened backup battery, corrupted travel limits and a blown fuse, all of which are inexpensive. Surge damage to the control board is tested for last, not first.
Pull the manual release and lift the door by hand. Heavy, dragging, or refusing to stay at waist height means springs or cables — a mechanical repair. Lifting easily by hand but not moving under power means the opener. We run that test first on every Darrenwood call-out.
Both figures are put in front of you at the Darrenwood visit. A capacitor, drive gear, limit switch or battery on a sound unit is well worth repairing. An obsolete unit with no parts available, or a failed board on a motor past about ten years, is normally better replaced.
Yes — the local brands fitted across Darrenwood are all covered, and the common spares travel on the van.
