door opens about 1 foot
When I press and release the opener button on the wall, the motor runs for a second or two. The door barely moves.
If I hold the button down, the door will move up very slowly. After it goes up about 1 foot, the rail (where the screw drive runs) seems to bounce up and down a bit before the door stops moving. The rail moving seems strange to me. The motor will not raise the door much further than this.
If I release the door from the carriage, I can manually raise and lower the door fully. I'm not sure if the force I need to lift the door is normal or not, but it doesn't seem overly difficult. If I open the door half-way it will stay there. If I hold down the opener button while the door is disconnected from the carriage, the motor will run as long as I hold down the button.
The opener seems fairly old, and doesn't seem to have any up/down force adjustment controls.
I had the spring replaced about a week or so before the door stopped working.
I recently put white lithium grease along the screw drive because the person who replaced the spring told me to. I may have put too much though (I have since wiped some of it off).

Shorting the screws does the same thing as the button right? What would adjusting the clutch or replacing the capacitor do?
