Tubular Motor Troubleshooting and Maintenance Guide
Trouble shooting
Common Issues and Professional Solutions
Tubular motors are essential components in automated systems for roller shutters, blinds, awnings, and zip screens. Though they are designed for long-term reliability, issues can occasionally occur due to power problems, wear, or improper setup.
This Tubular Motor Troubleshooting guide provides practical steps to identify and fix common problems, while our tubular motor maintenance tips will help you extend the motor’s lifespan and ensure optimal performance.
1. Motor Does Not Operate
When your tubular motor does not respond to any command, start by checking the power source and connections.
- Possible causes: power supply interruption, disconnected wires, or thermal protection activation.
- Solutions: verify power with a tester, check cable integrity, and ensure the circuit breaker is on. If thermal protection has been triggered, wait 15–20 minutes for the motor to cool before trying again.
2. Motor Moves in Only One Direction
A frequent Tubular Motor Troubleshooting issue occurs when the motor rotates only upward or downward.
- Possible causes: faulty limit switch, wiring error, or defective control relay.
- Solutions: inspect the wiring diagram, test the control switch or receiver, and reset electronic limits if your model supports it.
If the issue persists, test the motor directly to determine if the problem lies in the control unit.
3. Motor Overheats or Stops Suddenly
All tubular motors include internal thermal protection to prevent damage from overheating.
- Possible causes: excessive load, frequent operation cycles, or blocked roller movement.
- Solutions: reduce operation frequency, remove obstructions, and ensure the curtain rolls freely.
During routine tubular motor maintenance, verify that the torque rating matches the system weight to prevent recurring overload shutdowns.
4. Noise or Vibration During Operation
Unusual noise or vibration often indicates mechanical imbalance or installation looseness.
- Possible causes: misaligned tube, worn adapters, or loose brackets.
- Solutions: tighten all mounting points, check for tube deformation, and ensure the motor head fits snugly into the roller. A well-aligned system reduces vibration and extends motor service life.
5. Remote Control Malfunction
If the motor does not respond to remote control commands:
- Possible causes: remote pairing failure, low battery, or interference.
- Solutions: replace the remote battery, re-pair according to the user manual, and ensure no strong wireless interference near the receiver.
For reliable operation, include remote testing in your tubular motor maintenance schedule.
Preventive Maintenance Tips
Proper tubular motor maintenance significantly reduces failure rates and extends product life:
- Inspect wiring and terminals every six months.
- Keep the motor dry and free of dust.
- Avoid exceeding the rated running time or torque load.
- Test limit positions regularly to maintain accuracy.
- Lubricate moving components if required by the model’s specifications.
