Garage door repair
1. The drive device cannot be started with manual switch or remote control
Possible reasons: 1. The drive device is not connected to the power supply. 2. The manual switch or remote control receiving board is open. 3. Too many running times lead to motor thermal protection
Maintenance methods: 1. Check sockets, plugs, manual switches, and fuse fuses. 2. Check the wiring of the manual switch and the remote control receiving board. 3. Reposition the travel switch to increase the travel.
2. When the door is not closed tightly, it will automatically run in the reverse direction or when the door is opened, it will stop running midway without touching the travel switch.
Possible reasons: 1. The resistance of opening and closing the door is greater than the set opening and closing load force, which activates the obstacle sensing system. 2. Improper adjustment of connecting rod length.
Maintenance method: 1. Open the clutch device, check whether the door body and the torsion spring are balanced, and whether the opening and closing are flexible. 2. Increase the opening and closing load force. 3. Adjust the length of the connecting rod when the door is closed.
3. The manual switch can control the drive device but the remote control cannot
Possible reasons: 1. The manual switch can control the drive device but the remote control cannot. 2. The remote control system is malfunctioning.
Maintenance method: 1. Complete the code matching operation according to the instructions of the manual. 2. Replace the internal battery of the remote control. 3. Ask the maintenance personnel to check the receiving control board.
4. The door is not closed tightly or opened completely
Possible cause: The position of the travel switch is not adjusted correctly.
Repair method: reposition the travel switch to increase the travel.
5. The running noise of the door is too loud
Possible reasons: 1. The hardware installation is not firm. 2. The driving device pull rod is not located on the center line of the door. 3. The running rails of the door are not parallel. 4. No lubricating oil is applied to the hinges and rollers.
Maintenance method: 1. Firm hardware. 2. Adjust the pull rod of the driving device to coincide with the center line of the door body. 3. Adjust the running rails of the door to be parallel to each other. 4. Cover the hinges and rollers with lubricating oil.
6. The drive device operates normally, but the door does not operate
Possible cause: The load force adjustment of the headstock is not in place.
Maintenance method: readjust the opening and closing load force.
7. The operating distance of the remote control outside the garage is significantly less than 10 meters
Possible reasons: 1. The garage is heavily shielded. 2. The battery power is insufficient.
Maintenance method: 1. Extend the antenna to the outside of the garage. 2. Extend the antenna from the driver and straighten it. 3. Replace the battery.
8. The door body rushes through the travel switch
Possible cause: The travel switch is damaged or the travel switch wire is open.
Maintenance method: check the travel switch and the wiring of the travel switch.
9. The door body runs in one direction
Possible reasons: 1. The travel switch is damaged or the travel switch wire is short-circuited. 2. There are obstacles in the optical path of the photoelectric switch. 3. The load force adjustment of the opening and closing is not in place.
Maintenance method: 1. Check the travel switch and the wiring of the travel switch. 2. Clear the obstacles on the optical path of the photoelectric shape. 3. Readjust the opening and closing load force.
