When the door is lowered the spring winds up tightly creating a pulling force that helps lift the door up.
Tension springs you can work on yourself since they are under no load when the door is open.

If the door only moves a few inches and stops the rpm sensor could be bad.
If the spring is to small the door will be difficult to open if the spring is to large the door will be difficult.
An unbalanced door can make the door difficult to raise manually and can cause damage to other components in the garage door system.
