Look at it closely i ll bet it is jammed against the 5 16 bolt just in front of the motor unit.
Garage door opener hums but does not move.
Not the garage door the opener trolley.
There are several reasons why this could have happened but usually it may have simply slipped out it went up slightly crooked once or the weather may have caused it to become uneven when it closed.
The trolley doesn t move and the door does not budge.
Press the remote or the wall mounted start switch listen to the motor and watch the movement of the chain.
They can hear the motor going but the door itself is not opening.
The next step is to attempt to open your garage door manually.
I then ask the customer the approximate age and usage of the garage door.
If the motor hums but the chain doesn t move that indicates a problem with the motor.
This indicates that something in the opener system has malfunctioned.
This will determine if the issue is connected to the door itself or the opener.
Automatic garage door opener runs but door doesn t move sometimes homeowners will find that their automatic garage door opener runs but the door doesn t move.
There are mainly two reasons for this occurrence and one of the reasons is depicted in this blog.
Detach the opener by pulling the emergency handle downward.
You activate the door opener by either a remote control hand held unit or by pressing the wall button mounted on the wall and hear the motor humming but the garage door does not move.
Is it all the way in the up open position.
If so loosen the chain adjuster until it is no longer jammed against the bolt run the opener down a few inches and then unplug it.
If it is used frequently or is at least five years old odds are that it has a stripped gear kit.
The gear kit is made up of two plastic gears that move each other to engage the trolley and get everything moving.
This is frustrating especially if you re trying to get your car out of the garage.
If you are able to raise your garage door easily it is not the problem.
The first step is to locate the emergency release and disengage it do it only if the garage door is completely closed.
