Causes of Garage door motor hums but does not open problem
Let’s explore some of these culprits and see how we can pin them down;

Since the photo eye is situated a few inches above the ground, any interruption will shut the laser signal.
This will therefore make the motor hum but neither raise nor lower the door. You are required to diagnose for damages or cuts in the photo eye cord because it occasionally gets affected by a leak or rainstorm. Alternatively, dust and dirt can also block the eye, obstructing the laser beam.
Broken Torsion springs: This is the first component that will break in the assembly of your garage door. The motor will therefore hum but won’t roll down or up the door; it’s a toothless dog. You will hear frightening and loud noise like that of a gunshot or firecracker. You need to understand that these springs are assigned to specific cycles.
Popped off or broken cables: This complication goes hand in hand with the broken spring issue. Your cables are likely to be disengaged like on the bike sprocket. With damaged torsion springs, your garage door cable will have no otherwise but to snap.
Occasionally, these cables destroy the wall or vehicle and if you are in front of it, you may end up with serious injuries.

These doors are automatic in that they reverse when coming in contact with a certain object. There could be something that you can’t see easily, preventing your door from closing or opening. Sometimes it may open or close halfway.
Off track complication: Sometimes your garage door may be off track, meaning that it will not slide correctly. Diagnosing the problem means that you’ll have to check if the door sticks on the way or slows down. If this is the issue, then there is a misalignment in that area.
Your garage door will only operate smoothly if it rolls properly on the metal track.
