Garage Door Troubleshooting
Garage Doors and Garage Door openers are made up of fairly simple components. There are a number of things, however, that can cause problems with the everyday operation of an overhead garage door. Even though fairly simple, all the components need to work together to make everything function properly. Some of the most common problems can be corrected by the average homeowner, while others may require professional help. Torsion springs can be dangerous to adjust and replace, so we here at Steich Overhead Doors, recommend that you get the assistance of a professional door technician to work on these items.
Here are some of the most common problems you might encounter over the life of your garage door. Once you have identified the problem you can decide if you would like to take care of it yourself or call on a qualified professional. Hopefully these troubleshooting tips will help you better describe the problems you are having when you speak to a technician.
Your Garage Door is Making Some Strange Noises
- Noisy, squeaky door — Most likely the rollers, roller bearings and or the section hinges are lacking lubricant. You can apply lubricant to the rollers and hinges. The bearings may need replaced.
- Loud popping noise — This is normally due to a damaged roller(s) or a damaged or misaligned roller track.
- Loud scraping sound — Normally the end bearing plate is worn or needs lubrication. This item is the plate that supports the main shaft and cable drum at the top of the door (both ends).
Garage Door Opening Problems
- Door will not open — Broken torsion/extension spring, damaged roller track, the automatic door opener is not working, photoelectric sensor is misaligned or not functioning.
- Door will not stay open — Torsion spring is out of adjustment or if equipped with extension springs, the cable may need adjustment.
- Door doesn't close all the way —This could be due to a misaligned or damaged track, worn or out of adjustment spring or a worn cable pulley.
- Door Closes part way or reverses direction — Broken spring cable, misaligned dirty or defective photo sensors, worn cable pulley(s), the close/force is out of adjustment.
- Door opens too slowly or not completely — normally this is caused by a broken torsion spring
- Opener is humming or running but not activating the door — It could be the trolley is stuck on the stop bolt or stop tab, stripped gears or failed electronic components. We recommend you call a service technician for this situation.
- Garage door opener runs in the wrong direction — For chain and belt drive openers the trolley may be installed backwards or the opener could be out of phase. You would need to call your opener manufacturer customer support.
Garage Door is Uneven or Misaligned
- One side of the bottom is lower than the other — broken spring cable or worn extension spring cable pulley
- Door is Jammed — Broken spring cable, damaged track or worn extension spring cables.
- Electric Opener Doesn't Work — Check your remote control unit. Replace the batteries if necessary. You will most likely need to re-program the remote after changing the batteries.
