If your rolling door motor has failed, replacing it is usually more cost-effective than repairing it. Here's what to expect in Shenzhen.
Motor Cost
A standard domestic brand tubular motor for a residential garage door (lifting capacity 600 to 1000kg) costs roughly 600 to 1200 yuan. For a heavier commercial door, a 1500kg motor runs 1000 to 2000 yuan. Imported brands like SEW or Nice cost more, 2000 to 5000 yuan depending on specs. The motor is the main cost.
Labor Cost
In Shenzhen, expect to pay 300 to 800 yuan for motor replacement labor. The job takes 2 to 4 hours typically. Factors that increase labor: the door is very large, the motor location is difficult to access, or additional wiring work is needed.
What the Job Involves
The technician removes the old motor, checks the drive chain and sprockets, installs the new motor, aligns it, wires it to the control box, sets the limit switches, and tests the door through several cycles. If the old control box is compatible, it can be reused.
Additional Parts That Might Need Replacement
Drive chain (50 to 150 yuan), limit switch assembly (100 to 300 yuan), remote controls (80 to 200 yuan each). If the capacitor on the old motor failed, the new motor comes with its own capacitor, so that's not extra.
Total Ballpark
For a typical storefront electric rolling door in Shenzhen, motor replacement runs 1000 to 2500 yuan all in, depending on the motor brand and door size.
Before Replacing the Motor
Make sure the motor is actually dead. Sometimes the problem is simpler: a blown capacitor, a tripped thermal protector, a bad limit switch, or even just a dead remote battery. Get a diagnosis before committing to a new motor.
Warranty
New motors typically come with a 1 to 3 year warranty from the manufacturer. The installation labor usually has a separate warranty from the installer, often 3 to 6 months.
