We recently had a client with a very annoying problem. Every time he went to open his garage door, it would open part way but then immediately close again. Frustrating! You can see what we mean below:
When we got to his house, we started trouble shooting possible problems to understand why this was happening. We eventually landed on the problem: the door is too heavy for the opener to properly open the door all the way.
Upon further inspection, the reason the door is too heavy is because the torsion springs installed on the door are too small for this particular door. Properly fitting springs is a major safety feature and component to a properly functioning garage door.
As you can see below, once we switched out the old torsion spring to a new dual spring system, we adjusted the motor and the door is able to open and close safely.
We generally recommend to all customers that they install a dual spring system. Ensuring your springs fit properly is one important factor to the safe operation of your garage door. But a dual spring system goes a long way in extending the life of your springs and your garage door opener.
