Your garage door operates appropriately but fails to open or close typically. Here are some tips and tricks for tuning up a garage door so it works properly.
Check the springs for sag/tension
Most of the time, there is plenty of tension on garage door springs, even though the door may not work correctly. If you find too little pressure, some minor adjustments can remedy the problem by using a screwdriver to push one side up and back down when the appropriate amount of tension has been achieved. Spring sag is not a critical problem and can easily be remedied by using a simple screwdriver to push up on one side of the spring and then push it back down. Turn off the power to your garage door tune up, and always tune up the opener while doing this task.
Check the rollers for damage
Your garage door is supposed to roll up and down without any squeaking or grinding noises, but this rarely happens. Using emery grit on a grinding roller will eliminate the problem but will not solve the issue of a broken roller. It can be remedied by replacing one or both of the roller wheels with new ones, disassembling them, and cleaning them up with emery grit or fine sandpaper. If you are going to get new wheels, be sure to take measurements so that you find wheels that match your existing ones.
Check all hinges
The new ones should work fine if you have replaced most of your hinges. If the old ones are not working, you can use spray lubricant such as WD-40 to lubricate the roller on an old hinge or use a wire sander to sand down an old hinge so that it will work properly again.
Check all pulleys for damage or rust
If you have recently adopted spring additions and many of your hinges rotate around a pulley, this could be a wear issue, and you should fix it as soon as possible. The fix is simple: you will use spray lubricant like WD-40 to help clean the wheels of rust and then use emery grit or fine sandpaper to fix any sticking problems that may have arisen. If worse comes to worst, you can replace the pulley corners with new ones.
Check your opener
Restoring your opener is relatively easy, and you can achieve a better result when dealing with a problem washer. The best way to repair your garage door opener is to ensure that the identification number on your door opener matches the one on the opener itself. If in doubt, you should always research this before taking the remote control of your opener. You will likely have to find a replacement or substandard parts for your opener.
You have probably gone through several troubleshooting steps, including checking and repairing your spring tension, the operation of your opener, and the rollers. If you succeed, well done! If not, the best way to solve your problem is to hire a reputable garage door service. These guys always know what to do; they will help you avoid wasting your precious time and make repairs in the most efficient way.
