Garage Door Starts To Open Then Stops

Understanding the Mechanism

Before we delve into the troubleshooting process, let’s briefly understand how a typical garage door system works. A garage door operates through a combination of various components:

  1. Motor: The motor provides the power to lift and lower the garage door. It’s controlled by the garage door opener.
  2. Opener: The garage door opener, usually controlled by a remote or a wall-mounted button, activates the motor to open or close the door.
  3. Springs: Garage doors are equipped with either extension or torsion springs, which counterbalance the weight of the door and assist in its smooth operation.
  4. Tracks and Rollers: These guide the movement of the door, ensuring it moves up and down without friction.
  5. Safety Sensors: Located near the bottom of the door, these sensors prevent the door from closing if they detect an obstruction in the door’s path.
  6. Cables and Drums: These components work together to wind and unwind the door, aiding in its movement.

Common Causes of the Problem

When your garage door starts to open but then stops, several potential causes should be considered:

  1. Obstruction: One of the most common reasons is an obstruction in the door’s path. This could be an object blocking the door or even debris on the tracks.
  2. Misaligned Tracks: If the tracks are misaligned, it can cause the door to get stuck during operation. This misalignment may be due to loose bolts or damaged sections.
  3. Safety Sensor Issues: Sometimes, the garage door’s safety sensors may be misaligned or malfunctioning, preventing the door from closing. These sensors are a crucial safety feature.
  4. Spring Tension: Issues with the garage door springs can affect the door’s balance. If the springs are damaged or improperly adjusted, it can cause the door to stop during operation.
  5. Motor Problems: The garage door opener motor can develop issues, such as overheating or wear and tear, causing it to stop during operation.
