TROUBLESHOOTING - FREQUENTLY ASKED QUESTIONS

"My door goes up, but when I push the button, it only goes down part way or reverses and goes all the way back up. I have to hold the button in to make the door go all the way down."

This is a common problem when the photo safety eyes on either side of the door about 6 inches off the floor get bumped and become out of alignment. The purpose of these photo eyes is to prevent the door from closing on something or someone. When they have been bumped by a rake, snow shovel, or have something sitting in front of them, the door will not close. Make sure they are aligned (pointing directly at each other) and check any breaks in the wires to them. To get the door to close, hold the wall button in continuously — your car transmitters will not work.

"I heard a loud bang in my garage, and now my door won't go up."

This is most likely a broken torsion spring. The torsion springs are located just above the door inside the garage. Sometimes there is just one, and sometimes there are two — one on each side of the center. They offset the weight of the door and help lift the door either manually or with the electric opener. The spring(s) have a lifecycle, and will break after so many uses. It is recommended that both springs be replaced even if only one is broken because they need to be on the same lifecycle.

Do not remove or try to fix the spring unless you are a trained garage door technician. These springs are under a lot of tension and can cause serious injury or death.

Do not try to use your opener to lift the door. It is not designed to lift the full weight of the door, and will burn out or otherwise become damaged.

"My operator quit working and I can't get my door open."

If for some reason your operator quits working, locate the pull rope hanging from the "trolley" mechanism that opens the door. Pull the door to release the opener — you should now be able to open the door by hand.

"My opener makes an awful squeaking noise, and the chain (or belt) is really loose and hangs down."

This is normally caused by a bad sprocket assembly in the opener. These can normally be replaced by a trained technician. If the opener is a certain age, it is recommended the entire opener be replaced.

"I accidentally hit my door, can it be repaired?"

Depending on the amount of damage, a trained technician can many times straighten the door enough to get it down, and even working. They will sometimes add a reinforcing strut inside across the damaged area. Creases in garage doors cannot normally be repaired — many times a new section can be ordered that matches the existing section.

"The cables are off and in a tangled mess."

This usually happens when the door has come down on something or when a spring breaks. A trained technician can usually get the door operational.

Do not try to work with the cables on your own — they can be under tremendous tension and can cause serious injury or death.

"Will old transmitters work with my new opener?"

Sometimes old transmitters will work, but over the years, the frequencies have been changed and old transmitters will not work. Universal transmitters to cover many frequencies are available. These can be purchased from Door Tech.

"I just got a new car and want to program it to open my door."

Follow the instructions in your car's owner's manual. Some of the newer openers are not compatible with some built-in automobile transmitters, and require a separate repeater device to make them operate correctly. These can be purchased from Door Tech.
