How to maintain your garage door by yourself?
First you need to check the garage door manually- pull down the cable on the opener and than try to lift the door by yourself till your knees. If the garage door holds there and doesn't fall down it means everything is working fine, but if the door falls back down and hit the floor you will need to call immediately to the garage door technician because the torsion spring tension is loose and that is very dangerous. Do not try to adjust it by yourself! You will need to call a professional to do it because the spring tension is very dangerous. Remember when the spring tension is loose so there is more pressure on the garage door Opener and that can ruin the Opener Gear. Call the pros! 24/7 Corona Garage Door Repair (714) 552-2838
