1. Why does it reverse back up instead of closing?

Most likely, your safety eyes are out of alignment, or something is blocking the path of the garage door. The safety sensors/eyes need a clear line of sight between each other in order for the opener to travel downward. They’re usually black, and attached at the base of the tracks. Each should have a small LED light that remains lit when both sensors are properly aligned. If bumped out of place, they can be adjusted by hand so that they are pointing at each other again. It’s fairly common for the lenses on the safety eyes to become obscured by dirt or other debris, as well. Take a look at “The Garage Door Didn’t Close!” for more troubleshooting advice on garage door openers.

2. Why is it so heavy?

Garage doors are generally at least 8′ wide and 7′ high. That amount of material can really tip the scales, making it the largest moving piece of machinery in your home. That’s why there are springs and a counter balance system to take all that weight, and make it manageable. Remember manual keylocks, and doing things by hand? Openers don’t (or shouldn’t) pull any more weight than a person would when doing that job. That being said, springs can relax over time, making things heavier. Stripped gears, which are a very common repair, are caused by this type of problem. It’s generally a good idea to do some maintenance about once a year. Have a professional check for proper spring tension, and adjust them if needed.

3. Why won’t it go up? / Why is it stuck in the down position?

Take a look at the springs located on the wall above the garage door. There should be no break, or separation in the coils. Springs generally last for about 7 years, depending on the amount of daily usage. Again, these provide the force for balancing out all that weight. When one breaks, it can make things too heavy to lift, causing it to seem stuck in place. If one of yours is broken, you’ll probably need to call a pro. If you’ve seen no separation in the coils, try pulling the emergency release. This will allow manual operation, without the motor. It may be that they’ve relaxed to the point that the opener can’t lift the weight anymore. Hopefully, some of your questions have been answered.
