The Smart Hub: The smart hub includes a Bluetooth receiver for the door sensor, a 2.4 ghz radio to connect to your wireless home network for the system to communicate with Chamberlain’s servers on the internet, and a radio frequency (RF) transmitter to send HomeLink rolling codes to your garage door opener (on a channel in the 300-400mhz range depending on your garage door opener) - just like your remote clicker.
That sagging garage door is getting harder and harder to open. Garage doors, especially older, wooden models, are as susceptible to the ravages of time and gravity as the rest of us. If your aging doors are a little saggy, square them up with the tension rods positioned on the back of the door. The rods are placed diagonally from top to bottom corners and can be tightened at a turnbuckle to straighten out the door--do a little at time to allow the door to adjust to the change. If your door isn't already equipped with tension rods, you can buy them at home centers.
While a sudden issue is usually easily repaired, a consistent issue that has gone unaddressed for months or years will likely require a total replacement. The problem is that garage doors have a number of heavy, powerful moving parts. If the door is working as it is designed, it can open and close hundreds and hundreds of times without issues. However, if there is even a small issue in the lifting mechanism that repeatedly influences the movement of the door, you will soon find that the damage caused over those hundreds of lifts can’t be fixed.
Luckily, there is a bit of science to questions of garage door repair and replacement. That’s why we’ve put together this guide on when to replace a garage door. We’ll prepare you to compare repair vs replacement garage door costs. We’ll discuss the ways in which repairs are the most affordable option while also exploring those moments when replacement will in the end provide you with more value added.
The torsion springs on steel rolling doors work the same way as other torsion springs in the garage door industry. When the door is closed, the spring is wound. The spring is secured to a spring anchor bracket on one end and to the shaft on the other. When the steel rolling door opens, the spring in the barrel supports most of the door weight. The remainder of this weight is lifted by the chain hoist or the operator.
