The door cannot be opened and closed properly:

Clean up foreign bodies or debris around the door body to ensure that the door can open and close normally.

The motor does not rotate:

Check whether the power supply is unblocked and whether the capacitor is lost.

If it is a power problem, cut off the power supply, find the power line or replace the power capacitor.

Check whether the limit switch is working properly and replace it with a new limit switch if necessary.

Slow motor operation:

It may be that the motor load is too large, the power supply voltage is insufficient, or the motor aging and other problems.

Reduce the load on the motor, check the power supply voltage, such as the need to install a regulator if the regular voltage is insufficient.

If the motor is aging, consider replacing the motor.

Loud or harsh sounds:

Check whether the door and wheel path need to be filled with lubricating oil.

Check whether the upper and lower wheels of the door are loose, and replace them if necessary.

Door body deviates from the scheduled route:

It may be that the distance between the navigator and the ground is too high, it is recommended to lower the navigator to less than 25 mm from the ground.

The navigator may be faulty or damaged and need to be replaced with a new one.

Check the road for obstacles and remove them if necessary.

Electric retractable door stuck:

Could be a blocked rail or loose hinge.

Clean the debris in the guide rail, strengthen and adjust the hinge position.

Remote control is close or ineffective:

Check whether the transmitter antenna and receiving antenna are broken, and re-weld if they are broken.

Replace the battery of the remote transmitter and ensure that the battery model matches the original battery.

Check the surrounding environment to prevent interference sources from affecting the remote control.

Clutch problem:

Manual clutch failure may be the control handle is damaged or the clutch internal stuck, can replace the handle and output gear.

The motor works but the door body does not move may be the clutch is not engaged, need to check the status of the clutch and adjust.

Anti-climbing false alarm:

Check the position and condition of the anti-creep probe and re-align or replace the probe if necessary.

Other specific issues:

Improper correction: The correction reed tube may be too high from the ground, damaged, or the magnet is abnormal. Adjust the height, replace the reed tube, or check the magnet.

Dual motor cannot start: Check the power supply and switch and replace the fuse if necessary.

To prevent retractable doors from failing, you are advised to maintain and clean them regularly to ensure that the power supply, motor, switch, and guide rail work properly. At the same time, pay attention to the use of environment and operation methods to avoid problems caused by external factors.
