Some premium garage door openers feature an internal backup battery that will operate the garage door opener in the event of a power outage. The garage door opener will emit a beeping sound when it is operating off of the battery power or when the battery is no longer able to recharge. While the garage door opener is operating using the backup battery power the light bulbs will not turn on to conserve battery power.
Note: To obtain maximum battery life and prevent damage, always disconnect the battery if you unplug the garage door opener while on vacation or any other extended period of time.
Garage door openers that are equipped with a backup battery will have an LED diagnostic to indicate current battery status.
A garage door opening is the largest opening in your home. Insulated garage doors help to reduce the transfer of heat or cold air into your garage. If your garage is attached to your home, air in the garage can travel through the doorway to your living area. An insulated garage door will reduce the transfer of air from the outside to the inside. If you garage is below another room in your home, air can travel through the ceiling of the garage into the floor of the room above. An insulated garage door will keep temperatures in the garage fairly stable to reduce the temperature fluctuation in the room above. Furthermore, an insulated garage door is generally sturdier and quieter and has a more attractive interior than a non-insulated door.
R-Value is a measure of thermal resistance used in the building and construction industry. Specifically, R-value is thermal resistance to heat flow. many manufactures use R-value to show the energy efficiency of their product. This number is calculated based on the thickness of the insulation and its chemical properties. The higher the R-value number, the better the insulating properties of the material. A garage door's insulating capabilities can greatly be affected by the door's construction. For that reason, Amarr's® insulated garage doors are built to maximize energy efficiency. Amarr's® thermal break door section construction and insulation helps keep your garage as comfortable as possible and increases the energy efficiency of your home.
Garage door openers have an antenna allowing the communication with remote controls to open and close the garage door as you pull in the driveway. If your door will not open when you push the button on the remote and you are outside, but works if you are standing inside the garage, check that the antenna wire is hanging down from the garage door opener head. This will be a gray or purple wire hanging out from under one of the light lenses. This wire tends to get tucked up inside the light lens on occasion. But it must be hanging down to allow for full reception with the remote controls.
