是温度变化造成变形,继而导致车库门的传感器没有瞄准:在车库门两边靠近地面附近,有两个传感器,其一是发射,另一个是接受,当二者没有瞄准的时候,因接受器不能接收到发射器来的信号(即使发射器有信号),就作出判断认为是门有阻挡(或者车子或者人或者杂物),因此给出开门的信号。 c' n8 T3 P* J9 v& z. f o; x
My garage door has the same problem. I phoned Barcol and the guy told me it is a easy fix. Usually because the two sensors above the ground are not in alignment.8 K5 [: i8 S+ J6 i) a

The sensors are located on each side of the garage door. You can manually adjust to make them align. 7 R2 O- g$ d+ m0 }% G: i: j! s6 G8 r0 E7 b
