One Call Can Solve all your Garage Door Problems
Sears garage door? I can hear motor but garage door wont move up or down. chain is in place.
admin Many garage door openers use a big plastic gear as a safety mechanism. If the door meets an obstruction, the gear strips. Take the cover off and if you see a lot of white powder, thats the cause.You can buy replacement gears easily and they don’t take very long to put in.The gear is supposed to be greased frequently but nobody ever does and this is what eventually happens.
