Troubleshooting Your Garage Door and Opener
Garage doors and openers are generally reliable and should last for 10-15 years. It is important to know how your electric opener works and it is best to read through your owners manual to learn more about your particular model. Most garage door openers do not require regular maintenance with the exception of a screw drive opener. Screw drive openers need to be lubricated along the screw shaft at least once a year with white lithium grease or some other similar product. Garage doors should be looked over and lubricated at least once a year. Feel free to call us at any time with questions about your automatic garage door. Read the safety paragraph at the bottom before trying to fix your garage door.
Common Garage Door and Opener Problems
My Garage Door Won’t Close: Check the safety eyes located at the bottom of the garage door tracks on each side. Make sure that both sides have glowing lights that aren’t flashing or flickering. Clean the eyes and make sure there are no obstructions blocking the eye beam. Make sure the eyes are properly adjusted to point at each other. Check the wiring and look for loose or disconnected wires. Try bypassing the safety eyes by holding the wall button down until the door is shut. Check the emergency release cord and make sure it is engaged with the opener.
My Garage Door Won’t Open Or Close: Make sure that the emergency release cord hasn’t been pulled. For most models you can pull the release cord in the direction of the opener motor to reconnect the trolley. If you have a chain drive opener look above the opener motor. Is the chain wrapped around the sprocket? If not you may need a new gear and sprocket. If the trolley is engaged with the opener and the motor runs but the door doesn’t operate than you probably have a stripped gear.
My Garage Door Won’t Open: Locate your garage door springs and make sure they aren’t broken. Look above the door in the center for torsion springs and above the tracks for extension springs. Torsion springs will have a 2-3 inch gap in the coil when broken. Extension springs are often hanging down when broken. Disconnect the garage door while in the closed position. Does it lift easily? If not, call and have us look at it. Check your wall button for a lock switch and make sure your remotes and keypad haven’t been locked out.
My Garage Door Is Noisey: Go to the hardware store and buy some silicone spray. Lubricate the rollers, hinges, tracks, and pulleys with silicone spray. Make sure all the nuts and bolts are tight but don’t overtighten. Open and close the door manually after lubricating. Spray the opener rail with silicone lubricant. Reconnect the opener and operate the door with the opener two or three times. Listen for noises and lubricate as necessary. When lubricating doesn’t help it’s probably time to change some of that noisy hardware.
Garage Door and Opener Safety
Never try to adjust garage door springs without proper training. Garage door springs and cables are dangerous to work on while under tension. Never disconnect the door from the opener while in the up position because the door could fall and hurt or kill an animal or a person. When the garage door doesn’t seem to be working properly, look it over carefully before trying to open or close it. Make sure all the bolts are tight. Unplug the opener before trying to work on its internal parts. Call Acworth Garage Doors by CSS if you need assistance in Acworth, Woodstock, Kennesaw, Marietta, and Canton, Ga.
