There are two types of garage door springs: Extension and torsion. Springs play a crucial role of counterbalancing garage doors, hence making it easy for you to close and open the door. A counterbalance effect is similar to what people of the same weight would do on a see-saw. If the two stood on opposite sides of the see-saw, it would balance. Similarly, with a garage door weighing 100 pounds, you would need springs that exert a force equivalent to 100 pounds.
Important caution on garage door spring balance
This is not to scare you, but garage door springs can be very dangerous. Hundreds of people get injured due to springs suddenly snapping on them. There have been fatalities too. What should you do? Always notify your garage door expert in Dallas that you would like them to inspect the door.
When your door is not properly balanced
In the first place, when a garage door is out of balance, it does not reverse. Going back to the previous see-saw example, if one side is heavier than the other, the bar will lean on the heavier side. Similarly, when there is an imbalance on a garage door, the effect causes a malfunction on the garage door opener. You will notice that the door falls with a strong force or pulls back in an irregular manner.
Garage door testing
With these tell-tale signs, it would be most appropriate to inform a garage door expert. The expert will come and perform a balance test. It involves closing the door before disconnecting its opener. The technicians, then lift the door till it is halfway open. Thereafter, they release it slowly. If it drops too fast, it means the tension in the springs is low. On the other hand, if the garage door keeps going up, there is too much tension on the springs.
A perfectly balanced door should remain in place once opened midway. A series of adjustment from the Dallas garage door maintenance crew will help restore its balance. Hence, it is important to have your door inspected on a regular basis.
