If the tension is too loose the springs that help lift the door are ineffective and the weight of the door makes this unsafe.
Garage door won t open too heavy.
When the door is lowered the spring winds up tightly creating a pulling force that helps lift the door up.
If your garage door spring is failing or broken it will not provide enough force to lift the garage door.
If the door only moves a few inches and stops the rpm sensor could be bad.
If the motor doesn t run at all you may need to replace the garage door opener logic board.
The remote signal is blocked.
If the settings are off the opener will be tricked into thinking that the door is either too lightweight to require force or too heavy for the weight allowance of the opener.
Too much tension equates to a door that doesn t close all the way or.
Many doors we encounter do not have the proper size spring s installed.
Tension springs you can work on yourself since they are under no load when the door is open.

An unbalanced door can make the door difficult to raise manually and can cause damage to other components in the garage door system.
Although rare a failed drive motor is another reason why the door won t open.
Tug on it hard and it.
Torsion springs must be worked on with the door closed meaning there is no safe way to work on them.
If the spring is properly balanced lifting the door open shouldn t require too much effort and the door should remain in the halfway open position without starting to sag down.
Many garage doors have a powerful torsion spring located horizontally above the door.
If the spring is not the proper size the door will not be balanced.
