Garage Door Opener Starts To Open Then Stops

If your garage door opens and suddenly stops it might be because of your logic board.

Garage door opener starts to open then stops.

It goes partway down reverses direction and goes back up again. A torsion spring has. This is almost always the result of a dirty or obstructed safety feature. In order to fix this you ll want to make small changes to the close limit setting until the door opener knows to stop once the door has reached the floor.

Sometimes the limit switch is activated by the movement of a specially shaped nut traveling on this track. You push the button to close the garage door. If the door is working properly it should be easy to lift by hand. If your garage door is closing fully and then reversing to open again then it may be due to a problem with the close limit switch.

If not re engage it. Opener runs but the garage door does not move screw drive models make sure the carriage is engaged. You might need to consider replacing it if your door is not working properly or you may purchase a new opener. Check to make sure the chain belt assembly is not broken or off its pulley.

Open up the case and look for a screw type track that moves when the opener runs. The garage door can be operated manually by disconnecting the garage door opener from the door using the red pull cord. When the garage door ascends correctly but stops short it is fully open these are the likely causes. The up limit switch may need to be moved toward the motor unit.

When the door is fully open use a mallet to lightly tap the bent side of the track back into alignment. Check to make sure the pulley is not boken. This switch is usually a simply touch lever mounted on the end of the track near the motor unit and if it is too far away the motor will stop the door before it fully opens. Replace broken chain belts sprockets or pulleys.

When the opener is activated the screw rotates causing the nut to move until it reaches the switch. The logic board receives and responds signals to any remote.
