Common faults and solutions of electric remote control garage door opener:

1. 车库门开门机既不能从门控板也不能从遥控器操作：车库门开门机有电源吗？在插座中插入一只灯。如果灯不亮,检查保险丝盒或断路器。所有门都解锁了吗？重新阅读安装说明警告。门下是否有积冰或积雪？门可能冻到地面上了。清除障碍物。车库门弹簧可能断裂了。请合格人员进行更换。

1. The garage door opener cannot be operated from either the door control panel or the remote control: is the garage door opener powered? Insert a lamp into the socket. If the light is not on, check the fuse box or circuit breaker. Are all the doors unlocked? Reread the installation instructions warning. Is there ice or snow under the door? The door may have frozen to the ground. Remove obstacles. The garage door spring may be broken. Ask qualified personnel to replace.

2. 车库门开门机可以从遥控器操作但不能从门控板操作：门控板按钮亮吗？如果不亮,从车库门开门机终端拆卸电铃线。用一条导线同时接触两个终端使红,白终端短路。如果车库门开门机运转,检查门控板是否有接线 错误,U形钉下是否短路或者导线是否断裂。所有线路连接都良好吗？重新阅读安装说明书。

2. The garage door opener can be operated from the remote control, but not from the door control panel: is the door control panel button on? If it doesn't light up, remove the bell wire from the garage door opener terminal. Use a wire to contact both terminals at the same time to short circuit the red and white terminals. If the garage door opener operates, check whether there is wiring error on the door control panel, whether there is a short circuit under the staples or whether the wires are broken. Are all lines connected well? Reread the installation instructions.

3. 车库门开门机可以通过门控板操作但不能通过遥控器操作：必要时更换电池（一般国产电动遥控车库门车库门开门机遥控器的电池的使用寿命约5年左右）。如果你有两个或更多遥控器,只有一个起使用,重复“编程车库门开门机和遥控器”章节中详细说明的例行程序。门控按钮闪烁吗？此时车库门开门机上的锁定特点已被启用。如果你有一只多功能门控板,持续按下锁定按钮2 秒钟。门控按钮会停止闪烁。

3. The garage door opener can be operated through the door control panel, but not through the remote control: replace the battery when necessary (generally, the service life of the battery of the domestic electric remote garage door opener is about 5 years). If you have two or more remote controls and only one is in use, repeat the routine detailed in the chapter "programming garage door opener and remote control". Does the door control button flash? At this time, the locking feature on the garage door opener has been enabled. If you have a multi-function door control panel, press the lock button continuously for 2 seconds. The door control button will stop flashing.

4. 遥控器范围不足：安装电池了吗？改变遥控器在车中的位置。金属车库门,背部有箔的绝缘或金属挡板会缩小传输范围。

4. Insufficient range of remote control: is the battery installed? Change the position of the remote control in the car. Metal garage door, insulation with foil on the back or metal baffle will reduce the transmission range.

5. 没有明显的原因门作反向运动,而且车库门开门机灯不闪烁：有什么东西挡住门了吗？拉动释放柄。用手操作门。如果它不平衡或者卡住了,应找来合格人员进行修理。在车库门关闭的地方,从车库地面上清扫冰或雪。重复说明书中“设置极限”和“设置力”章节中详细说明的例行程序。进行任何必要的调整后,均应重复安全反向测试。

5. There is no obvious reason why the door moves in the opposite direction, and the light of the garage door opener does not flash: is there anything blocking the door? Pull the release handle. Operate the door by hand. If it is unbalanced or stuck, get qualified personnel to repair it. In the place where the garage door is closed, remove ice or snow from the garage floor. Repeat the routine detailed in the "set limit" and "set force" sections of the manual. After making any necessary adjustments, the safety reverse test shall be repeated.

6. 门没有明显的原因即反向运动并且反向运动后车库门开门机灯闪烁5秒钟：检查防护系统（红外传感器）（如果安装了这个附件）。如果发光二极管指示灯闪烁,则校正对准。

6. The door has no obvious reason, that is, it moves in the opposite direction, and the garage door opener light flashes for 5 seconds after the reverse movement: check the protection system (infrared sensor) (if this accessory is installed). If the LED indicator flashes, correct the alignment.

7. 在生活小区里,车库门开门机的噪音扰民：如果由于车库门开门机靠近生活小区,正常的操作噪音成为问题,建议安装隔振器套件 。该套件设计为减少“共鸣板”效应,并且易于安装。

7. In the living quarter, the noise of the garage door opener disturbs the residents: if the normal operation noise becomes a problem because the garage door opener is close to the living quarter, it is recommended to install the vibration isolator kit. The kit is designed to reduce the "soundboard" effect and is easy to install.

8. 车库门自行打开和关闭：确保遥控器上的按钮没有卡在“开”位置上。

8. The garage door opens and closes by itself: make sure the button on the remote control is not stuck in the "on" position.

9. 门停止,但不能完全关闭：重复“设置极限”一节中详细说明的例行程序。对门臂长度,关闭力或向下（关闭）极限进行任何调整后,应重复安全反向测试。

9. The door stops, but cannot be completely closed: repeat the routine detailed in the "setting limits" section. After making any adjustment to the length of the door arm, the closing force or the downward (closing) limit, the safety reverse test shall be repeated.

10. 门可以打开但不能关闭：检查防护系统（红外传感器）（如果安装了这个附件）。如果发光二极管指示灯闪烁,则校正对准。如果车库门开门机灯不闪烁而且设备是新的,则重复说明书中“设置极限”和“设置力”章节中详细说明的例行程序。权：进行任何必要的调整后,均应重复安全反向测试。

10. The door can be opened but not closed: check the protective system (infrared sensor) (if this accessory is installed). If the LED indicator flashes, correct the alignment. If the garage door opener light does not flash and the device is new, repeat the routine detailed in the "set limit" and "set force" chapters of the manual. Right: after making any necessary adjustments, the safety reverse test should be repeated.

11. 车库门开门机灯不亮：更换电灯泡（较大24V/21W）。用粗制的维修照明灯泡更换有缺陷的灯泡。

11. The light of garage door opener is not on: replace the electric bulb (larger 24v/21w). Replace defective bulbs with rough maintenance lighting bulbs.

12. 车库门开门机发出吱吱嘎嘎的响声：门可能不平衡或者弹簧断裂。关闭门并用手动释放绳和手柄断开滚轮。用手打开和关闭门。妥善平衡的门可以停留在行程的任意点,并完全由弹簧支撑。如果情况不是这样,应找来合格人员纠正问题。

12. The garage door opener creaks: the door may be unbalanced or the spring may break. Close the door and disconnect the roller with the manual release rope and handle. Open and close the door by hand. Properly balanced doors can stay at any point of travel and are fully supported by springs. If this is not the case, qualified personnel should be called to correct the problem.

13. 车库门开门机电动机暂时有嗡嗡声,然后不工作：车库门的弹簧可能断裂。见上。如果问题发生在初次操作车库门开门机时,则门是被锁定了。解除门锁定。进行任何必要的调整后,均应重复安全反向测试。

13. The motor of garage door opener buzzes temporarily, and then does not work: the spring of garage door may break. See above. If the problem occurs when the garage door opener is operated for the first time, the door is locked. Unlock the door. After making any necessary adjustments, the safety reverse test shall be repeated.
