After prolonged use, garage doors are bound to encounter various issues. If the motor is running but the door remains stationary, it could be due to a broken chain or a blocked track. In this case, you need to inspect the chain and clear any foreign objects from the track. If the motor fails to start, first check if there's a power supply problem or if the remote control battery is dead. Promptly replace the battery and examine the power source.
The door's movement can also be troublesome. Jerky operation is often caused by a deformed track or damaged rollers. Simply adjust the track and replace the rollers to fix it. If the door can't fully close or open, the limit switch may be inaccurate, and you'll need to readjust its position. Safety device malfunctions are also common. If the sensor triggers an alarm, check if it's misaligned or covered with dust, then clean and realign it.
Don't panic if the remote control stops working. First, try replacing the battery. If that doesn't solve the problem, there may be signal interference or the remote could be damaged. Move away from interference sources or re-pair the remote. Environmental factors can also have an impact. In cold weather, the door may freeze and get stuck. Using anti-freeze lubricant and clearing the ice layer will resolve this issue.
Regular maintenance is essential. Lubricate the tracks and rollers periodically and inspect the safety devices. For complex faults, such as spring adjustments, don't attempt to fix them yourself. Contact professionals to ensure safety and peace of mind!
