When you know you’re in range and the door still won’t open, check to make sure the antenna is hanging down from the motor inside your garage and nothing is blocking it. Your antenna must be free from any obstruction to clearly receive the signal to open and close the door. Also inspect the antenna for any signs of damage. If it looks like there has been damage to the antenna, you’ll need to call your garage door technician to come out and replace it.

8.5 Inspect the bearing. Lube it with motor oil, spray lithium, or spray lubriplate grease. Do not use WD-40. If the shaft is worn and the bearing is seized and you can't free it, replace the bearing. Or, if you have bearings labeled "ADH" we recommend replacing them. I find very few other bearings that need to be replaced. However, if you do need to replace the bearing and you do not have a new one, you can replace it at a later date. You'll find a quick way to do this at our End Bearing Plate Replacement instruction page.
1. Garage door springs do almost all of the work of lifting your door regardless of the door being manually or automatically operated. The spring makes it possible for anyone to lift a product that might weigh one hundred pounds on the low end and many hundreds of pounds on the high end. Not only can anyone lift it – most can do it with one hand! In other words, the garage door spring does a lot of work.
If the door won’t move at all because of an alignment issue, then this problem isn’t one that you should try to tackle yourself. A garage door professional will have the necessary equipment needed to safely realign and repair your garage door. Additionally, if the track misalignment is beyond repair, a professional can install a new garage door track for you.
While a sudden issue is usually easily repaired, a consistent issue that has gone unaddressed for months or years will likely require a total replacement. The problem is that garage doors have a number of heavy, powerful moving parts. If the door is working as it is designed, it can open and close hundreds and hundreds of times without issues. However, if there is even a small issue in the lifting mechanism that repeatedly influences the movement of the door, you will soon find that the damage caused over those hundreds of lifts can’t be fixed.

If you are not sure if your door had the correct springs, we recommend that you weigh your door using an analog scale. From my own field experience I would estimate that at least 10% of the doors have the incorrect springs on them. In addition to this, most manufacturers spring their doors using a 20 pound window. We like to improve the garage door balance.
