當我按下車庫內部的按鈕以將門關閉時,門將嘗試下降,電機指示燈會閃爍,並且門又會重新升起。我必須按住牆壁的按鈕才能使門真正落下並關閉。

The garage door will automatically reverse if it encounters too much resistance or if the sensor beam is interrupted.
To check for resistance, start with the door closed and pull the red handle. Then open and close the door. The movement should be fluid with no tough spots. If you encounter difficult spots, you likely have a bent track, a broken wheel, or a severe lack of track lubricant. Call a professional.
If the door opens with the opener fine, but reverses almost immediately when you try to close it, then you likely have a problem with your sensor alignment. One sensor should have a light on all the time. This is the transmitter. The other, your receiver, should light up when it has an unobstructed view of the invisible light beam the transmitter sends. It's easy to bump a sensor and move it out of alignment. Just bend it back in to position. Use the light on the receiver to help you so that you don't have to try and close the door to check your adjustments.
我想在線程中添加我的經驗/觀察結果:同樣的情況-除非您按住內部按鈕,否則不會關閉,錯誤會閃爍10次。
我的兩個傳感器都“似乎”在工作。也就是說,當我將它們對準時,琥珀色的發射器將使綠色接收器點亮,如果我阻擋了光束,綠色的接收器將熄滅,因此正如我所說,它“似乎”正在工作。
原因是接收器導線腐蝕。幾年前,兩條電線都被小動物割斷了。我將它們拼接起來,但是濕氣和天氣導致線路上的阻力足夠大,無法提供不一致的反饋並觸發安全控制。我剪下不良的銅並焊接了一個新的接頭,然後用膠帶將其密封,然後一切都恢復了正常。
總之,如果兩個傳感器均亮起並且您收到了阻擋光束的響應,請檢查綠色接收器接線(發射器不會有相同的問題)。使用萬用表,您可以查找電壓波動或電阻,或者僅通過肉眼檢查線路絕緣和黑色或綠色銅線是否斷裂。電線比傳感器更有可能,那麼為什麼要浪費錢呢?
上週我遇到了這個問題。傳感器上的燈很好。最終,該問題歸因於傳感器之間的連接鬆動。斷開傳感器的連接,重新捆紮導線,然後重新連接。現在門關好了。
我認為,直到傳感器門的電源由於佈線錯誤而中斷時,傳感器才能正常工作,直到車庫門開始移動為止。
Besides @longneck's excellent points, if the garage door or opener is a new installation and has not worked before, it could be that the opener's internal "tension sensor" is not correctly set.
If the door can be reasonably easily opened and closed by hand, but the opener balks at closing the door, the tension setting probably needs to be increased. See the installation manual for details how to adjust it. Usually it is a nut inside the unit, or sometimes a thumbwheel.
如果此處沒有任何操作,請確定是什麼在欺騙自動反轉。我有一扇隔熱門。由於過多的熱量(絕緣層會被孩子剝落),絕緣層上的部分覆蓋層會剝落。當門從關閉處移到一英寸或兩英寸以內時,最下部面板上的床單蓋瓣正在觸發他倒轉。修剪掉床單的折板並保存...每次都可以工作。
傳感器燈熄滅(每個傳感器側都有綠色和紅色LED指示燈)。我移動了一個擴展梯子,該梯子必須“扭曲”了為傳感器供電的天花板角線。我上去,“搖動”天花板上的電線,LED燈亮了。車庫門現在正常關閉。如果其他情況都無法解決,請嘗試此操作。
我的兩個傳感器都在工作(只有光束被阻擋時,綠色接收器才會熄滅)。我注意到關門時一個燈泡閃爍了。我決定卸下燈泡並嘗試一下。好吧,門現在關好了。我不需要第二個燈,所以我不必費心找出是燈泡還是打開器上的連接引起了關閉問題。
