- If your garage door won't work, check the batteries on your transmitter. Check the transmitter on the wall of your garage and the one in your car; you may have to replace both.
- If your photo eye is out of alignment or dirty, your garage door won't close.
- The metal track that your door runs on needs to be properly aligned. Gaps between the rollers and rail or bends in the rail will make the door dangerous to operate.
- A garage door that opens or closes randomly may be an indication of a transmitter that is stuck. Check for anything lying on the control mechanism. It's also possible that a neighbor's garage opener is on the same frequency as yours and is opening your door every time they open theirs.
- Debris on the tracks can cause the reverse mechanism to activate. If your door closes part way and then opens again, make sure the tracks are clean and there are no objects blocking the sensors.
- The torsion springs are responsible for lifting the garage door. If the springs are broken, the garage door opener will not be able to lift the door. Springs are very dangerous to work with. Don't try to repair them yourself; call a professional.
- A broken tension spring or broken cables can cause the garage door to close with a bang. Both of these components are dangerous to work with; call a garage door specialist to repair the door.
Reasons to Hire a Professional to Repair Your Garage Door
- Friends and family can be hurt if the garage door fails and falls on someone. A broken tension spring or cable can hit someone with enough force to cause serious injuries. If the repair fails and someone gets hurt, you could be held liable.
- Many home insurance companies will only pay for damage if the repair is done by a professional.
- If you try to repair the door yourself and it fails, you may cause irreparable damage. A professional repair is much less expensive than a complete replacement.
- An improper repair may result in an unbalanced door. The garage door will be harder to open and may allow pets and weather to enter the garage.
- If you sell your home and any damage is caused by a faulty door repair, you may be liable. You could be responsible for court fees, medical bills, and repair costs.
- Most professional garage door companies warranty their work. If the door doesn't work after the repair, the technician will come back and make sure the problem is fixed.
