Homeowners often face the frustrating issue of their garage doors not closing all the way. This not only hampers convenience but also poses a risk to the security of valuable items stored inside.
DIY Repairs to Save Costs
Troubleshooting your garage door can potentially save you the cost of professional service calls. Here are some common steps to identify and resolve the issue.
Steps for Troubleshooting
Check Sensors:
Ensure safety lasers near the floor are clean to avoid false signals.
If sensors are blinking, they may require realignment.
Inspect Tracks and Rollers:
Ensure there are no obstructions, and check for bent tracks or damaged rollers.
Grease rollers to prevent them from sticking.
Examine Trolley Mechanism:
Ensure the trolley isn’t in bypass mode; pulling the rope can reset it.
Remote Control Issues:
Replace dead batteries; if still non-functional, the remote may need reprogramming using the “learn” button.
Adjust Limit Screws:
Adjust screws that determine how far the door opens/closes, ensuring it closes all the way without bouncing back.
Consult the Manual:
Blinking lights on the opener may indicate specific issues; refer to the troubleshooting guide in the manual.
Manually Close the Door:
If repairs are inadequate, secure the garage by pulling down the bypass rope or using bolts in track holes for locking.
