Garage Door Starts to Close Then Goes Back Up: Troubleshooting and Solutions

I’m sure many homeowners have experienced the frustration of their garage door starting to close but then reversing back up. It can be a confusing and annoying issue, especially if you’re not sure what’s causing it. In this article, we’ll explore the possible reasons why your garage door reverses and provide a detailed guide on how to troubleshoot and fix the problem.

Before we dive into the technical details, it’s important to understand the basic components of a garage door opener. The opener is the motor that powers the door, and it’s connected to a series of sensors and safety features that ensure the door operates smoothly and safely. If any of these components malfunction, it can cause the door to reverse.

Possible Causes and Troubleshooting

Here are some of the most common reasons why a garage door starts to close but then goes back up:

  1. Obstructions in the Doorway: Check the path of the door to make sure there are no obstructions blocking its movement. This could include objects like toys, bikes, or even snow and ice.
  2. Misaligned Sensors: The photoelectric sensors near the base of the door emit beams of light that must be aligned properly. If the sensors are misaligned, the door will reverse to prevent it from closing on an object.
  3. Faulty Wiring: Loose or damaged wires can disrupt the electrical signals that control the door’s movement. Inspect the wiring for any cuts or breaks.
  4. Bad Circuit Board: The circuit board in the opener controls the door’s operation. If the circuit board is damaged, it can cause erratic behavior, including reversing the door.
  5. Improperly Adjusted Travel Limits: The opener needs to know how far to travel in both the open and closed positions. If the travel limits are not set correctly, the door may stop or reverse prematurely.

Tips and Expert Advice for Troubleshooting

If you’ve checked for obstructions and the sensors are aligned, here are a few expert tips to help you troubleshoot the issue further:

  • Reset the Garage Door Opener: The reset button is usually located on the opener motor. Press and hold the button for 5-10 seconds to reset the system. This may resolve minor glitches.
  • Check the Rollers and Tracks: Damaged or bent rollers or misaligned tracks can cause resistance and prevent the door from closing properly. Inspect the entire system for any obvious issues.
  • Test the Force Sensitivity: If the door seems to be closing too quickly or hitting objects, adjust the force sensitivity on the opener. This can be done using the adjustment screws or buttons on the motor unit.
