2. Disconnecting the Power Supply and Ensuring Safety

Safety should always be a top priority when working with garage doors. Before proceeding with any repairs, disconnect the power supply to prevent accidents. Make sure to follow the manufacturer’s instructions for your specific garage door model. It’s also advisable to wear safety gear, such as gloves and safety glasses, to protect yourself during the process.

3. Adjusting or Replacing Broken Springs

Broken springs are one of the most common issues with garage doors. If you notice a broken spring, it’s crucial to replace it promptly. Begin by releasing the tension from the springs using the appropriate tools. Then, carefully remove the broken spring and replace it with a new one, following the manufacturer’s instructions. Remember to balance the tension on both sides to ensure smooth operation.

4. Aligning or Replacing Misaligned Tracks

Misaligned tracks can cause your garage door to operate unevenly or get stuck. To fix this issue, inspect the tracks for any obstructions or debris that may hinder smooth movement. If necessary, gently tap the tracks back into alignment using a rubber mallet. In case the tracks are severely damaged, it may be best to replace them altogether.

5. Fixing or Replacing Faulty Sensors

Garage door sensors play a crucial role in ensuring safety by detecting any obstructions in the door’s path. If your door refuses to close or keeps reversing, there may be an issue with the sensors. Begin by cleaning the sensors to remove any dirt or dust that may be interfering with their functionality. If cleaning doesn’t solve the problem, check for loose connections or damaged wiring. Replace the sensors if necessary, following the manufacturer’s guidelines.
