Step 3: Broken Garage Door Springs
Garage door springs play a very important role in smoothly closing and opening the door. They provide the required tension to your garage door so that it can open and close easily.
With time these springs broke down due to too much tension and continuously bearing the weight of the garage door.
Inspect these springs if they are broken or not. If the springs break, your garage door opener is unable to lift the door, if its motor is running.
There are two types of springs used for a garage door:
- A large spring that is situated just above your garage door. Most modern garage doors come with this large torsion spring.
- Old garage doors have a pair of extension springs located just above the door.
Broken garage door springs are difficult to replace on your own because the springs carry lots of tension, if you try to lose its screw, then it could be harmful to you.
This is why taking the help of an expert technician is always best.
Step 4: Inspect The Roller Of Your Garage Door
Rollers are located on the corner of both sides of your garage door top assembly. Sometimes they become stuck and don’t move as they should. Lake of greasing is the main cause of this issue.
Step 5: Loose Pulleys And Cables
There are two pulleys and cables that are attached to the roller of your garage door.

Step 6: Loose Screws
Your garage door has lots of screws. Some are located around the springs, and others are on the rollers. Inspect them and tighten them properly if you found they are loose.
Step 7: Garage Door Opener Chain Is Too Tight
Check the tension on the chain, by touching it with your fingers. If it swings a little bit, it means the tension on the chain is perfect, but if it doesn’t swing up and down it means the chain is too tight.
A tight chain makes it difficult to lift the garage door. A tight chain experience excess tension on it which causes the gear of the motor grind that moves the chain.
2. Troubleshoot The Garage Door Opener Motor
If you are hearing the running sound of your garage door opener motor but The chain, Belt or screw is not moving, it means some parts of the motor are worn out and need replacement.

And the last reason would be the incompatibility of your garage door opener with your garage door. There is a chance that the opener would not generate enough tension, and is incompatible in respect of the size and weight of your garage door.
