Garage Door Switch
In addition to a remote control, garage door openers typically have a hard-wired wall switch inside the garage to open and close the door without needing to use a wireless remote. Similar to a doorbell switch, a push-button garage door switch sends a signal to the door opener to raise or lower the door. If the switch isn’t operating the door properly, you can diagnose the problem and replace a wall switch to a garage door opener in a few minutes with some common hand tools.

If the remote works but the wall switch doesn’t, you may need to replace either the wall switch or the switch wires. To determine whether the switch or the wires are bad, first unscrew the switch from the wall and touch the two wires together (don’t worry, the wires are low voltage and won’t shock you). If the opener runs, you have a bad switch. If you have an older-model opener, a cheap doorbell button might work. If you have a newer opener that has a light and a locking option on the switch, buy the one designed for your model. A new one should cost you about $15.

All garage door openers manufactured and installed in the United States since 1982 are required to provide a quick-release mechanism on the trolley that allows for the garage door to be disconnected from the garage door opener in the event of entrapment. The quick-release handle should be mounted no higher than six feet from the ground. Homeowners should be familiar with this mechanism, because garage door springs can relax over time, and pulling the release could lead to a free-falling door. Garage door openers manufactured since 1982 are also required to reverse the garage door if it strikes a solid object.

The first garage door opener remote controls were simple and consisted of a simple transmitter (the remote) and receiver which controlled the opener mechanism. The transmitter would transmit on a designated frequency; the receiver would listen for the radio signal, then open or close the garage, depending on the door position. The basic concept of this can be traced back to World War II. This type of system was used to detonate remote bombs. While novel at the time, the technology ran its course when garage door openers became widely available and used. Then, not only did a person open their garage door, they opened their neighbor’s garage door as well. While the garage door remote is low in power and in range, it was powerful enough to interfere with other receivers in the area.

Replace the garage door opener wall control using the step-by-step instructions in this DIY repair guide. The wall control is mounted inside the garage, next to the door leading into the house. It opens and closes the garage door, and switches on the light on the garage door opener. If you push the control button and get no response from the door, the control is defective. Replace it using a manufacturer-approved replacement part. If you have to hold down the control button until the door closes completely, the problem likely is with the safety sensors. To replace the safety sensors, see the guide How to Replace the Safety Sensor on a Garage Door Opener.
Plug in the opener or turn on the circuit breaker. Inspect the switch to see if the switch is lighted. If it is not lit, unplug the opener or turn off the same breaker, then remove the switch and reverse the two wires on the back of the switch before reinstalling. Plug in the opener or turn on the breaker to see if the switch is illuminated. If the switch light is on, press the opener to test the unit’s operation.

If you want to add more functions and integrations, you can do so with the Gogogate2 without having to buy a separate home-automation hub, as you do with the MyQ Garage and the GoControl. With the free IFTTT app, you can fully automate your garage door’s opening and closing through a combination of voice and geolocation. During our testing, we were able to tell our Amazon Echo to open the garage door while we were in the house, after which we walked into the garage, got into the car, and drove away as the door closed behind us. Upon our return, the door sensed our approach courtesy of an IFTTT connection and opened; we drove into the garage, hopped out of the car, walked into the house, and told the Echo to close the garage door. IFTTT may not be for everybody, but during our trip, no button pushing of any kind was involved, nor did we need to get the phone out while driving.
The typical electric garage door opener consists of a power unit that contains the electric motor. The power unit attaches to a track. A trolley connected to an arm that attaches to the top of the garage door slides back and forth on the track, thus opening and closing the garage door. The trolley is pulled along the track by a chain, belt, or screw that turns when the motor is operated. A quick-release mechanism is attached to the trolley to allow the garage door to be disconnected from the opener for manual operation during a power failure or in case of emergency. Limit switches on the power unit control the distance the garage door opens and closes once the motor receives a signal from the remote control or wall push button to operate the door.
A smart garage-door controller is an excellent security and access tool for your home, vacation home, or rental property. An estimated 71 percent of American homeowners use the garage door as the main entry point to the home, and being able to open and close it remotely is very convenient. For example, if you or another member of your household often forgets to shut the garage door while driving away, a smart garage-door controller will tell you it’s still open and let you close it remotely. The device will also give you a heads-up if you leave the door open when you come home, or if it’s open when it shouldn’t be, so that you can close it from wherever you are, even if that’s just the couch. You can view the status of your garage door at any time, so you can be sure your home is safe and secure.
As in an elevator, the electric motor does not provide most of the power to move a heavy garage door. Instead, most of door’s weight is offset by the counterbalance springs attached to the door. (Even manually operated garage doors have counterbalances; otherwise they would be too heavy for a person to open or close them.) In a typical design, torsion springs apply torque to a shaft, and that shaft applies a force to the garage door via steel counterbalance cables. The electric opener provides only a small amount of force to control how far the door opens and closes. In most cases, the garage door opener also holds the door closed in place of a lock.
The Chamberlain MyQ Garage (MYQ-G0201) is the leading smart garage-door controller available, largely due to the huge popularity of Chamberlain garage-door openers (and those sold by its professional install brand, LiftMaster). The MyQ was the first smart garage-door controller to be manufactured, and it’s one of the simplest smart-home devices to install and set up. If you are looking for a way to control your garage door remotely and check on its status, and would like some basic integration with major smart-home systems such as Wink and Nest (Apple HomeKit compatibility is promised soon), the MyQ Garage is the best option.
The electric overhead garage door opener was invented by Edgar David Lilja. In 1932, Edgar’s garage had the first prototype installed at 421 Robert Ave, Rockford, Illinois. Electric Garage Door openers did not become popular until Era Meter Company of Chicago offered one after World War II where the overhead garage door could be opened via a key pad located on a post at the end of the driveway or a switch inside the garage.
An intermediate stage of the garage door opener market between the second and third stages eliminated the DIP switches and used remotes preprogrammed to one out of roughly 3.5 billion unique codes. This system was backward compatible with the DIP switch remote codes, and each remote code (either with DIP switches or with a unique preprogrammed code) can be added into the receiver’s memory by pressing the learn button on the opener, and can be deleted from the receiver’s memory by holding it. While the code transmitted by the remote was still fixed, it was not changeable by the user (except if using legacy DIP switch remotes) and thus was much more difficult to duplicate unless two remotes shared the same code (which was very unlikely since the odds of two remotes sharing the same code was 1 out of roughly 3.5 billion except if legacy DIP switch remotes were used). This approach was an improvement over the fixed DIP switch codes, but was soon rendered obsolete when rolling code (which generates a new code on each press) devices became available.
