If you are the mechanical type and comfortable with tools, you can try the following to troubleshoot any maintenance issues you are having with your garage door.
Residential garage doors usually roll up in sections and they operate on spring tension. The power is also provided by the heavy spring that moves on metal tracks on the garage walls.
With a few basic tools you may be able to make some repairs yourself, and save the need to call a technician. Try following these steps:
A. Take a look at the metal tracks inside the garage. Examine the mounting brackets that hold the tracks to the walls. Use a screwdriver or wrench to tighten the bolts or screws at the brackets. Close the garage door and examine the tracks for dents or crimps. You may be able to hammer out any damaged spots with rubber mallet, or using a regular hammer with a block of scrap wood. If the tracks are badly damaged, you should call a technician.
B. Check the alignment of the tracks with a level. They should be level. If they are level, check to ensure tracks are at the same height on the garage walls and the horizontal tracks should slant slightly down toward the back of the garage. If the tracks appear out of alignment in any way, DO NOT REMOVE the screws or bolts that hold the mounting brackets. Call a professional immediately as this may result in serious damage or injury.
C. The tracks and rollers need to be lubricated with garage door lubricant for powdered graphite in the tracks. If you have pulleys, use the same lubricant that you used on the rollers.
D. One of the common items to wear out are garage door springs. If you have extension springs, the spring should be hooked into notches or holes. DO NOT try moving the spring to another hole to change the tension. A spring cable or pulley controls the roll-up doors. DO NOT try pulling the cable as you may damage the door, immediately call a professional technician.
