Perform routine monthly maintenance.
- Inspect the garage door springs, rollers, pulleys, cable, and track. Visually determine if anything seems to be different. Are the parts rusted? Is the cable sagging?
- Lubricate the moving parts of your garage door. Use spray oil like WD-40 to lubricate all moving parts - for example, the garage door hinges, the torsion spring, and the chain. Never lubricate the plastic parts.
- Check the garage door balance. Start with the garage door closed. Pull the emergency release mechanism, and then manually open the garage door. See if it hovers 3-4 feet above the floor after you've opened it slightly. If the door closes to the ground, the door is out of balance and needs to be repaired by a professional.
- Replace the garage door batteries. If you're not having any luck using your garage door opener remote control, it's possible you need to replace the batteries. Most remote controls work on AA, AAA, or watch-style batteries. Take the old battery to any drug store or electronics store to match the battery type you need.
- Try not to park in the middle of the garage. If you have roll bars on the top of your vehicle, it might catch the emergency release mechanism's handle as you pull into the garage. Try parking on the sides of the garage if possible to avoid snagging the emergency release mechanism and damaging the garage door opener power unit.
- Make sure the electrical functions of the garage door are working. If it's not operational, check the fuse box to see if the breaker has tripped, or check the lock button on the wall located near the main open/close button. The lock button is a safety feature that helps prevents injuries, and if the garage door is locked in this manner, it won't work properly. Change the light bulbs regularly in your garage door opener unit (if applicable).
- Test the reversing feature of the garage door. Put a piece of wood on the ground so that the door comes down and touches the wood. The door should touch the wood and reverse immediately. If your garage door opener is older than 1993, it's possible that it does not reverse by itself and you need to consider replacing the garage door opener. Federal safety standards require modern garage doors to reverse in this manner.
- Keep your garage door clean. Clean the door regularly with a mild detergent and soft brush. Washing the door reduces the buildup of corrosive elements. Swat away cobwebs from the sensors to keep the garage door from opening or closing improperly.
Once you've inspected visually your garage door and performed some minor, do-it-yourself tasks, you might determine that things still aren't working properly. Under no circumstances should you ever attempt to unfasten bolts or the high tension cables and springs. You may unleash a barrage of projectiles and become a human target. Many people have been harmed (and even killed) because they chose to take on certain garage door repair jobs themselves. Always leave the tough tasks to the garage door professionals.
