Q: How often should a garage door motor be serviced in South Africa?
Garage door motors should be serviced annually. Service includes spring tension check, drive rail and roller lubrication, safety auto-reversal test, limit switch calibration, battery backup load test, and motor capacitor condition check. Neglected torsion springs under up to 200kg tension can fail suddenly, causing injury or damage to the door and vehicle.
What the annual garage door service covers
✓Torsion spring tension check — balance measured; unbalanced springs cause motor overload and sudden failure
✓Drive rail and roller lubrication — dry rollers cause motor strain; correct lubricant applied (not WD-40)
✓Safety auto-reversal test — door must reverse on 50N obstruction; safety-critical compliance test
✓Limit switch calibration — open and close travel limits adjusted to prevent door over-travel
✓Battery backup load test — real backup duration measured under actual door operating load
✓Motor capacitor check — failing start capacitor is the most common motor failure point; measured and replaced if weak
✓Door panel and seal inspection — bottom seal and panel condition checked for weatherproofing and security

The spring failure risk
A torsion spring stores the energy required to lift a 60–150kg garage door. When a spring fails, it does so instantly and with significant force — it can damage the door, motor, and anything nearby. Annual tension checking identifies springs approaching end of life. Proactive spring replacement costs R800–R1,200. Emergency replacement after failure costs R1,800–R3,500.
Frequently asked questions
What brands does HomeGuard Pro service?+
Centurion (RDO, RAVE, SLIDEMASTER), Merlin, B&D, and generic DC motor systems.
My garage door is noisy — is that a service issue?+
Yes. Noise indicates dry rollers or a worn drive belt/chain. Left unattended, the motor compensates for increased friction, accelerating wear.
Can the service be done with my car inside?+
Yes. The door is tested in both directions with the technician controlling movement. Your car remains safely inside throughout.
