This is similar to the post "Garage Door Won't Open All the Way"
I have a Genie Door Opener Model GX9000 Screw Drive. Probably around 1994.
It will open a short distance then stop, If I press the button again it goes the other way. It sounds like the motor is really strained, like it is running at half speed, like it is a 220V that dropped a leg.
The door is a sectional and I can raise it manually very easy, plus I released the door from the screw, so that takes it out of the equation.
I have kept the screw greased and the door rollers lubed. I can turn the motor by hand from the back where the tension adjust is and it turns the motor and screw easy.
So is the motor shot??? If it is I was looking at this one.
Genie Powerlift Plus 1/2 HP Screw Drive Garage Door Opener. $177.00 online $208.00 delivered to the door. Or does someone recommend a different one?
I thought of pulling the screw from the motor and seeing how the motor runs then, but that I didn't want to get into all that if someone knew what was wrong.
I don't have the money for a new one if I can fix this one, but I guess $200 isn't too awful bad if I have to replace it.
