1 Please be safe while inspecting the door!

Take your time with cleaning and do not attempt to adjust the spring above the garage door. It's wound tight, and any mistake can cause serious injury or death. If you think that there's a problem with the spring, call a professional garage door expert immediately!

2 Inspect the tracks, rollers and hinges (they are the components that keep the garage door together).

Dirt and oil can collect in these components and hinder their operation. Use your best efforts to clean them up with a damp rag. If they are really dirty or greasy, you can try using paint thinner.

3 With the garage door closed, inspect the hinges and brackets and make sure that the bolts and screws aren't loose.

If they are, tighten them up with a wrench.

4 Now it's time to lubricate!

Lack of lubrication puts additional strain on the garage door, so apply ample amounts of garage door lubricant spray or powdered graphite in the tracks (your local hardware store should have these materials in stock). – Do not use a wet lubricant because it will attract dirt and grime. –Wipe away excess lubricant with a paper towel or rag.

5 Take a look at your weather stripping at the bottom of the door.

If it doesn't make a tight seal when the door is closed, it's time to replace it.

6 Finally, test the electronic eye at the bottom of the garage door track to make sure it works.

Place a two-by-four in the path of the eye and press the button to close the door. If working properly, the door should not budge more than an inch.

7 Some garage doors have a pressure sensor instead of an electronic eye.

Place an object in the path of the garage door and press the button to close the door. If working properly, your garage door should reverse immediately when it hits the object.
