Troubleshooting Steps

Step 1: Checking for Obstructions

The first step is to visually inspect the garage door tracks, rollers, and hinges for any obstructions. Debris, loose items, or even ice and snow buildup can hinder the door’s movement. Carefully remove any obstructions you find to ensure smooth operation.

Step 2: Testing the Safety Sensors

Garage doors are equipped with safety sensors near the bottom to prevent accidents. Over time, these sensors can become misaligned or dirty, causing the door to stop prematurely. Check the sensors’ alignment and clean the lenses if necessary. This simple adjustment might resolve the issue.

Step 3: Examining the Limit Switches

Limit switches control the open and close positions of the garage door. If the switches are incorrectly set, they can cause the door to stop prematurely. Locate the limit switches and carefully adjust them according to the manufacturer’s instructions. Take caution not to overadjust, as this can lead to further issues. If you’re uncertain, it’s best to consult a professional.
