What horsepower do I need to lift my door?
You can make sure your garage door is properly balanced and is not sticking or binding: 1.Lift the door about half-way open as shown. Release the door. If properly balanced, the door should remain in place, supported entirely by its springs. 2.Raise and lower the door to see if there is any binding or sticking. The door should move easily, without dragging or becoming difficult to move. An easy rule of thumb is that a 10-year-old child should be able to lift and lower the garage door with little or no effort. If the door is hard to lift, the door must be serviced and adjusted by a professional authorized dealer.
Which model is better, the chain drive, the belt drive or the screw drive?
Each style of "drive system" has its advantages. Chain drive and belt drive openers work well in all types of applications. Screw drive openers are better choices when you have a one-piece tilt open door, as they run slightly slower, and allow a smoother movement of the one-piece type of doors.
Belt drive openers are the smoothest, most quiet openers we manufacture, and have an excellent reliability record. They are recommended for use whenever noise and vibration are important considerations. If there is a living space above or near the garage, the belt drive openers will minimize the amount of noise generated by the opener. Chain drive openers have been in production for the longest amount of time, and offer dependable performance year in and year out. Regardless of which type of opener you choose, all of our drive systems are very reliable and require virtually no maintenance throughout the life of the opener.
It is time to replace my garage door opener. Can I just replace the motor head and reuse the existing rail and other hardware?
This is rarely possible or appropriate way to replace your opener. Due to change in the design of the systems, and for warranty purposes, it is strongly recommended that all new components are used for the new opener. In addition, although it may seem to be an easier way to install a new opener, it may actually be more difficult to attempt to replace only the motor head.
What is the different between AC and DC motors? What are the advantages of each type of motor?
AC Motors are less expensive and easy to manufacture. Speed is constant and hard to control efficiently. DC Motors are more expensive as they are more complex to manufacture. Also, additional components are required to make them work with the standard AC current found in homes. Speed can be controlled more easily with a DC motor and more accurately. They have a quick response to control signals. Due to easier speed control, DC motors can be used in applications where powerful but in control performance is desired, such as the Liftmaster soft start/stop feature.
