Why does garage door opener only move a few inches?

Garage door opener will only move a few inches back and forth even with the door disconnected from the rail. I already replaced the sensors and checked the switches on the rail.

Check the spring above the door, mine would go up a couple of inches and we found that the spring had broke.

Remove the cover from the motor unit and check the drive gear. It is a white nylon gear just in front of the motor and may be stripped. If so you will also find what looks like white sawdust inside the motor unit.

It moves up a few in. then stops. Then you push the button again it closes hard aginst the floor. I disconneted the dr andf it still dose the same thing.


The opener has lost track of what is open and closed. This MIGHT be due to damaged gears, but first get a manual and do the initial setup work.

You could disconnect the motor and manually move the carriage back to where is should be, then engage the motor again.

If this is a chain drive, the chain may have slipped cogs until it thinks the door is up when it is only inches up.

Power shuts down when I try to close or open


Your motor may be working too hard anad ripping the reset button on the garage door,
Try increasing the power on the unit ( should be some type of dial.) or the door may be jamming up somewhere, Try disconnecting the opener from the door and see if it goes up easily, the door might need service

My garage door opener moves about 8" then reverses direction before touching the limits


Remove the cover and take a look at the drive gear. It is white nylon and is just in front of the motor. It is most likely stripped. You can purchase a new one at Sears or any good door opener company. It comes with instructions.
