2. The safety sensors may need adjustment or realignment. Near the bottom of the door track on both sides are electronic eyes that require a clear line of view between them. If the sightlines are clear between the eyes, the door will close smoothly all the way to the floor. However, if anything is blocking the sightline, or if the brackets holding the electronic eyes are out of alignment, the door will fail to descend all the way. In most cases, the door will stop or reverse, and lights will flash to tell you there is a problem. 


The tech that serviced your door must not understand simple mechanics. The tracks do not move, so they do not need to be lubricated. All that does is make a mess. The rollers and hinges DO move, so it is logical to lubricate them, at the hinge barrel or pivot point, and in the little area near the stem of the rollers where you can see the bearings. Adding a bit of lube to the torsion spring also cuts down on the friction between the coils and makes the spring glide easier. However, too much will make it spritz out lube as the door opens and closes, and that it less than desirable. Same thing for pulleys on an extension spring door.
Clint and James called and checked if my son had any problem with them showing up earlier than planned . No biggie there, they came, they examined , and they brought my sons busted garage door back up to a fully operation system . While the cost was more than myself or my son expected , the results were undeniable . A complete system review showed many worn or weak spots in his 14-15 year old bearings and such . They replaced what was needed and door works great . Next stop my house , all I needed was a replacement door seal . After talking with the tag team , I decided to go for the full Monty , and get an update to my bearings etc. Just to protect my wife in case I am not around to jack hammer a door open with a busted spring . Which would likely not work anyway ! Longer story short ...great outfit , good team , nice guys , job well done !! If you need any garage door work ...Precision Overhead Door is the place to call . Thanks very much for a great job guys ....Tedread more
Garage doors cause injury and property damage (including expensive damage to the door itself) in several different ways. The most common causes of injury from garage door systems include falling doors, pinch points, improperly adjusted opener force settings and safety eyes, attempts at do-it-yourself repair without the proper knowledge or tools, and uncontrolled release of spring tension (on extension spring systems).
Roller doors ("Sheet Doors"-USA) are usually constructed of corrugated steel. They evolved from cover window and door coverings.[4] Other materials can be used (e.g.; transparent corrugated fibreglass) where strong impact resistance is not required. Corrugations give the door strength against impacts. A typical single car garage roller door has a preloaded spring inside the rolling mechanism. The spring reduces the effort required to open the door. Larger roller doors in commercial premises are not sprung (except USA) and use a manual pulley and chain system or a geared motor to raise and lower (roll up and roll down) the door. Roller doors cannot be effectively insulated.
With over 300 independently moving parts, your garage door is a deceptively complex piece of equipment. To help prevent malfunctions and break-downs, it is a good idea to occasionally perform a garage door tune-up to keep all of these parts in good working order. A regular tune-up service by a Sears professional can prevent unexpected door problems and prolong the life of your existing equipment.
Thank you, thank you, thank you for sharing your knowledge. I just replaced our shower cartridge and our leak is FIXED!!!!!!! Your instructional was clear and concise. I did purchase 2 cartridges first, because I did not know the type it was and could not pull it out without the plastic cover it comes with. Fortunately, it was one of the two. By the way I'm a 63 year old woman. If I can do it, anyone with internet and a little patience and an hour can do it.....
The garage we take for granted very likely stores thousands of dollars worth of tools and household belongings, not to mention your automobiles. Yet this space is typically rather easy for intruders to penetrate. Garage security can be greatly improved by installing a modern garage door opener that features rotating digital codes, which can foil even the most tech-savvy prowlers.
10The type of garage door shown provides the necessary lift assistance with a “torque tube.” If you intend to use an opener, wait to install the tube. Otherwise, install the torque tube according to the manufacturer’s directions. Roll up the door about 4 feet to check for the alignment of the tracks, and make any adjustments. Then tighten all fasteners.

It is precisely on those coldest days of the year when you most need and appreciate the convenience of opening and closing your garage door quickly. Sadly, that's exactly the kind of day when moisture and cold can conspire to make this difficult. Garage doors can and do freeze to the garage floor. Sometimes it is just a minor icy connection between the two that can be broken when you hit the opener button. If the door refuses to budge on the first attempt, though, resist the urge to keep banging on the automatic opener button. This is likely to cause a more serious problem with the garage door opener—including, but not limited to, stripped gears, broken springs, and a burned-out motor on the opener.
