One of the first things to check is the photo eye, which detects the presence of any obstruction. Over time, the photo eye can become clogged with dirt and other debris. To clear it, you can wipe it with a damp rag. If the eye is not working properly, you may have to contact an Automatic Garage Door Repair service. If you're experiencing a noise that is accompanied by a creak or a grinding noise, you may have a problem with your garage door's torsion spring.

You should also ensure that the opener is in the center of the door. This will allow you to see it open and close. Then, you can attach a drawbar, which balances the weight of the door at the lifting point. Lastly, make sure that you have a step ladder underneath the motor to prevent damage to the garage.
