How to fix a screw-drive garage door opener?
My husband was backing into our garage today with a load on his truck. The release rope caught on the edge of something, pulling the rope tightly. Now the GDO won’t work automatically. It is a screw-driven unit. What does he need to do to re-engage the screw drive?
Screw drive openers are very reliable garage door openers. depending on the opener brand that you have Genie or LiftMaster the problem may be as simple as disengaging the emergency release cord and pressing the lever back into position until your hear or feel it click into place.
Another point you may not want to overlook is the garage door stile, where the connecting arm from the opener connects to the garage door. Test the opener first. to test the opener disconnect the cotter pin the attaches the curved arm to your garage door and once the lever that disengages the carriage has been put back in its normal position run the garage door opener to make sure that the opener rail or carriage is not damaged and that it runs smoothly.
If your garage door passes this test, go ahead and connect the curved connecting arm to the garage door. You will also want to visually inspect the stile on the garage door for damage. to make sure that the garage door opener bracket is still securely connected to the garage door stile( the garage door stile is the metal brace in the center of the garage door, there are also stiles placed on the ends of the garage door for reinforcement).
If the screws on the bracket where the arm connects to the door are loose, tighten them before you connect to opener arm back to the garage door. Run the garage door opener a couple of times and listen for problems or unusual noises. If everything goes fine your problem is solved.
If your carriage is damaged and no longer works you can purchase one from one of the links below. This is a simple operation that most homeowners can perform on their own. if you need to purchase the parts you can get them at one of the links below for 20 – 30 dollars. Common names for this part are screw drive carriage or screw drive trolley. You look for the part by this name should you need to purchase one.
You can also call and have a garage door professional inspect your opener for you. A reputable company will usually go out and give you a free estimate for a repair and inspect your garage door and opener for you if you don’t feel comfortable with D.I.Y projects.
In the future you may want to trim the size of the emergency release cord( the Red Cord) to avoid being caught on your vehicles to avoid any future damage.

Understanding the Drive Options for Garage Door Openers
Every evening the noise of the garage door opening foretells the return of loved ones all over. Not all garage door openers are the same, though. When differentiating between them there are a few criteria to look at first, horsepower and then the type of mechanism that uses that power.
Horsepower relates not to the strength required to lift the garage door independently, but rather the force necessary to lift the door given all the pulleys and springs. The opener, be it mechanical or human, is merely breaking the pull of inertia on the door. The size, materials, and quality of the door will help one determine how much power is really necessary.
If the door is especially heavy or large, and therefore has more inertia; ones choices are limited. Chain drive garage door opener units provide the most power and durability. They are going to be noisy, but that noise is the result of a lot of horsepower pulling a large chain. The mechanics are similar to those of a bike chain. These are generally the cheapest solution, but the noisy chain may not be a pleasant greeting every time one comes home. If the garage is not directly below or next to a bedroom this may not be a problem.
Screw drives are a good option for balancing noise level and cost. They often have extra features to protect them against more extreme climate conditions, but truly the strength of these openers is their value to noise ratio. There are fewer moving parts and many customers will find the difference in noise from a chain drive to a screw drive to be more than enough to make the switch worth it. The screw drive moves the door up and down in the same way that a nut revolves around a bolt and moves up and down in the process.
If the device is located directly under a bedroom or some other consideration makes quiet performance a priority, a belt drive is the best option. This type of drive is more costly than screw or chain drive, but the price of uninterrupted nap time may be worth it. These follow the same mechanical process as chain drives, but a belt like those found in most car engines is the moving part rather than a noisy, interlocking chain.
The three major types of garage door opener drive are all available for the Do-it-Yourself type as well as professional installation. Some models designed for professional installation offer enhanced noise buffering systems not offered. Some models will even offer a battery backup in case of power failure. These and other extra features will help one make a final decision, but understanding how the garage door opener functions will help anyone make a more educated choice.

WIll a screw drive garage opener install the same as a chain drive?
My old liftmaseter chain-drive died and I bought a genie screw drive opener and just wanted to know what i could expect when i go to install it, Can i use any of the stuff off the old opener like the sensors the previous ceiling mount for the motor and the header anchor for the bar, the wiring like for the sensors or the wall control or will i need to re do all this stuff from scratch?
Thanks
Most new genies come with the sensors, But if not your old ones if still in good condition will be fine. The only thing you may need is new angle mounting strips. You will be happier with the screw drive unit.

Promised Land [CD-ROM] Queensryche’s follow-up to the double-platinum Empire is something of an acquired taste, but it’s well worth the effort. There’s considerable variety here; the heavy progressive-rock of “I Am I” and the ballad “Bridge” were hit singles, but there’s also the funk-inflected “Disconnected”, the edgy, spooky “Lady Jane”, and the piano-and-vocals “Someone Else?”. The title track is probably the stronge… |
