Why Won’t My Chamberlain Garage Door Fully Open?
Before you learn how to fix your Chamberlain garage door opener, you have to understand why your garage door won’t open. Some of the most common reasons why your garage door won’t open include:
Track Aren’t Aligned Properly
When the automatic garage door opener activates, the cables physically maneuver the door while the strings control its speed. The metal tracks keep the garage door in line and help the operating system function efficiently. The garage door tracks must be straight and even at all times for the garage door to open and close.
A crooked door that jerks around or makes grinding noises could have fallen off the track. Over time, as misalignment worsens, the garage door could stop working.
To assess whether the garage door track is misaligned:
- Be gentle with the door: If your garage door won’t fully open, forcing the door open or closed could damage the door. Dealing with the garage door forcefully could bend the vertical tracks and pop the door out. Protect yourself and your property by carefully trying to maneuver your door.
- Use your eyes and ears: Make sure the door is gliding smoothly along the track. Check the track for bends, gaps, or obstacles. Listen to and watch the door’s path along the track. If you hear areas of friction or see jams along the track, a misaligned track could be the issue.
- Adjust the tracks: Before making any adjustments to the garage door track, check that the door is completely closed. For an extra safety measure, turn off the automatic feature on your garage. To realign the garage door into the track, loosen the screws that hold the track to its frame. Gently tap the track back into its proper position and tighten up the screws again. The overhead track should be the same distance away from the door as the wall track.
- Make an appointment with your garage door company: Call in a professional garage door technician to examine your garage door and put it back on track. They will touch up the tracks and rollers by cleaning off the dust and debris. They will also check and tighten any of the track’s loose hardware.
Broken Garage Door Springs?
A broken spring repair is one of the most common reasons why a garage door is not opening. Garage tension springs store mechanical energy that controls the movement of the garage door. Wear and tear could weaken the tension springs, which could lead to the garage door not working.
Garage door springs offset the weight of the garage door to open and close the door smoothly. These springs are featured in both manual and automatic garage door systems. Two torsion springs run horizontally over the width of the door, while two extension springs lift and lower the door along the track.
The torsion springs on the garage door could be broken because of:
A garage door opens and closes about 1,500 times each year. Depending on the rating of your tension springs, they could last several years before they need to be replaced. You could hear the loud noise of a spring rupture from inside the house.
You know the garage door tension springs are broken if:
- Wear and tear: Each spring is rated according to its number of cycles. Once a torsion spring has used up all its cycles, it stops working. Springs that have been used excessively are known to snap abruptly while the door is in motion. In some cases, a spring breaks before its projected expiration date.
- Rust: A development of rust on the tension springs increases friction on the coils as it moves. To prevent your tension springs from breaking due to rust, spray the springs with a silicone-based lubricant at least once every season.
- Improper maintenance: Inspecting the tension springs at least once a year can help you prepare for the end of their lifespan. If you notice the tension springs are weakening over time, be proactive and replace them before they break.
- The motor is running, but the door isn’t moving.
- You hear a loud sound like a firecracker coming from your house.
- The garage door starts to feel heavy as you try to manually maneuver it.
- The garage door makes straining noises.
Occasionally check the tension springs for damage. While broken tension springs are inevitable for old garages, they are dangerous and should be handled with care.
If your garage door has broken tension springs, use caution when examining it. Since a garage door weighs over 200 pounds, you could damage the garage door or injure yourself if you try to fix it on your own. Garage doors with broken tension strings can drop without warning and could be a danger to you and your family.
Call a professional garage door company to replace your garage door springs. Garage door professionals have the right skills and equipment to complete the task safely.
