Sears 1/2 hp GDO replaced Gear...I have a ?
I replaced the broken gear on my GDO. It seems that the trolley is moving the opposite direction. When I press the button, the trolley moves down the track and hits the bolts at the end of the track. When it hits the bolt, it returns back a few inches. I have the same GDO in my other garage and the trolley moves the opposite direction when you press the button. The sensors are clean and aligned, and I labled my wires before unplugging them and reinstalled them correctly.
Thanks in advance.
