Gate Motor & Garage Door Repairs in Pretoria

Common gate motor faults and their usual causes

A gate that misbehaves can have an electrical, electronic or mechanical cause, and the symptom often points to which. These are the faults most often reported.

• Remote does nothing: a flat remote battery, or the remote has lost its coding and needs to be synchronised with the receiver again
• Gate stops halfway or reverses: an obstruction, a dirty or misaligned safety beam, or the motor sensing too much resistance
• Motor runs but the gate doesn't move: a worn pinion or gearbox, or the rack has come loose from the gate
• Gate is slow or struggles: worn wheels, debris in the track, or the gate has come off its track
• Gate only works for a while: a backup battery that no longer holds its charge
• Gate dead after a storm: lightning or a power surge has damaged the controller

When the gate, not the motor, is the problem

A gate motor is only as good as the gate it drives. If a sliding gate is hard to push by hand when the motor is disengaged, the motor is fighting it every cycle, which wears the gearbox and drains the battery.

Mechanical repairs mean clearing stones, sand and leaves from the track, replacing worn wheels and guide rollers, straightening a bent track, and making sure the rack meshes evenly with the pinion along the gate's full length. Swing gates need sound hinges and posts that haven't shifted.

Batteries, ants, moisture and storm damage

Backup batteries wear out with age and repeated charging. A gate that opens sluggishly or stops working overnight often has a battery that charges but can no longer hold it, and a simple test shows whether it needs replacing.

Ants and other insects like the warmth inside a motor housing and can build nests across the controller board, causing erratic behaviour or a dead unit. Moisture getting in during the summer rains corrodes connections, so a cracked cover or missing seal is worth mentioning.

Highveld thunderstorms between roughly November and March bring lightning and power surges that can damage controllers, receivers and safety beams. Note in your enquiry whether the fault started straight after a storm.

Installing or replacing a gate motor

A new gate motor suits a manual gate that is sound, straight and moves freely by hand, or replaces a motor that is worn out or no longer worth repairing. Sliding and swing gates use different types of motor, and the choice also depends on the gate's weight and how often it's used.

Every gate motor installation needs a mains power supply. Connections to the mains must be done by a registered electrician, who issues a Certificate of Compliance for the work, so mention in your enquiry whether there is already a power point near the gate. The contractor can explain how that part is arranged when they quote.

Electric fences are a separate specialist field with their own installer requirements and certificate, so electric fence work isn't covered on this page, even where the fence and gate are linked.

Sectional, roll-up and tip-up garage doors

Garage door repairs in Pretoria depend first on the type of door. Sectional doors are made of horizontal panels that run up on tracks to sit under the ceiling. Roll-up or roller doors coil around a drum above the opening. Tip-up doors are a single panel that swings up and out on a pivot frame with side springs.

Each type has different springs, tracks and hardware, so knowing which you have, or sending a photo, helps the contractor understand the job before they visit.

Garage door faults: cables, springs, rollers and motors

Garage door faults tend to show up as a door that hangs crooked, feels heavy, makes new noises or stops responding to the remote.

• Door hangs crooked or one side drops: a frayed or snapped lifting cable, or a cable off its drum
• Door suddenly very heavy or won't lift: a broken spring
• Grinding, jerking or scraping: worn rollers, bent tracks or loose track brackets
• Dented or warped panels: often from a car bump, which can also bend the track
• Motor hums but the door doesn't move: the door is jammed or out of balance, or a drive part has worn
• Remote or wall button doesn't respond: a flat battery, lost coding or a receiver fault

Safety: springs, safety beams and manual release

Garage door springs hold a great deal of tension, and adjusting or replacing them, or loosening the brackets and cables attached to them, can cause serious injury. Don't attempt spring or cable work yourself.

Never bypass or disconnect a safety beam or obstacle detection to get a gate or door working; have the fault repaired instead. Keep children and pets away from moving gates and doors, teach children not to play near the track or ride on the gate, and store remotes out of their reach.

Most gate and garage door motors have a manual release that disengages the motor so the gate or door can be moved by hand. Follow the manufacturer's instructions, including switching off the power if they say so, move it slowly and keep hands clear of moving parts. Re-engage the motor afterwards, or the gate or door stays unsecured. A garage door with a broken spring may be too heavy to lift safely by hand.

Maintenance, makes and models, and complex gates

Keeping the gate track clear, checking that garage door rollers run smoothly and having both looked at before the summer storm season, when moisture, insects and surges cause the most trouble, prevents many faults. The manufacturer's manual sets service intervals, and moving parts should only be lubricated where and how it specifies, because the wrong product attracts grit.

Gate and garage door motors differ between makes and models, and parts and controller boards aren't interchangeable. The contractor will confirm which makes and models they handle, so a photo of the motor and its label helps.

Shared entrance gates in complexes and estates are normally common property, so repairs are arranged through the body corporate, HOA or managing agent.
