Troubleshooting Guide
Garage Door Will Open But Won't Close
Written by Nir S. Garage Door Technician – B&W Garage Doors
Encountering a garage door that will open but refuses to close can be frustrating. Luckily, B&W Garage Door in Calgary has compiled a straightforward troubleshooting guide to help you address this common issue.
Follow these steps to diagnose and potentially solve the problem:
Step 1: Check the Sensors
- Action: Inspect the safety sensors located at the bottom of the door tracks. Ensure they are clean, aligned, and unobstructed.
Misalignment or blockage can prevent the door from closing. - Tip: Wipe the sensors gently with a clean cloth and adjust their position until the small LED lights on both sensors are lit steadily.
Step 2: Examine the Tracks for Obstructions
- Action: Look for and remove any debris, objects, or build-ups that might be in the tracks. Even small obstructions can stop the door from closing.
- Tip: Use a flashlight for a thorough inspection and clear any obstructions carefully.
Step 3: Check the Remote Control and Wall Switch
- Action: Attempt to close the door using both the remote control and the wall switch. If the door closes with the wall switch but not the remote, the issue might be with the remote.
- Tip: Replace the batteries in the remote control and try again.
Step 4: Adjust the Close Limit Switch
- Action: Consult your garage door opener’s manual to locate and adjust the close limit switch. This switch instructs the motor when to stop running, and incorrect settings can prevent the door from closing.
- Tip: Make small adjustments and test the door after each change.
Step 5: Inspect for Loose or Damaged Components
- Action: Check for any loose cables, springs, or hardware.
Be cautious and do not attempt to repair high-tension parts like cables and springs yourself. - Tip: Contact B&W Garage Door in Calgary for a professional inspection if you suspect damaged or loose components.
Step 6: Reset the Opener
- Action: Sometimes, resetting the garage door opener can resolve the issue.
Turn off the power to the opener, wait a minute, and turn it back on. - Tip: Refer to the owner’s manual for specific reset instructions for your model.
