Garage door openers are often plagued by radio frequency with devices around the house. These signals sometimes can prevent the opener and the remote functioning correctly when attempting to open/close the door. In order to diagnose and solve some problem it is important to understand what could be causing the interference.
What Are The Most Common Types Of Interference?
A common problem that can cause disruption to your systems can be caused by these 3 main froms of interference like noise, overload and spurious emissions. Let’s look more closely at each of these interference types.
Interference From Noise
Noise interference happening when an electromagnetic noise source such as a bug zapper, thermostat, neon sign or electrical switch disrupts signals between two devices. This noise can also affect nearby neighbors and in some cases may be caused by dangerous arcs in someone’s electrical wiring or equipment, indicating a need for repair.
Interference From Overload
Sometimes powerful signals from other transmitting devices can overload your system which is not designed to process these signals. For example, if you have an older garage door opener it may respond to powerful signals from a nearby cell phone tower even though this signal is not meant for your device. Modern day devices are designed with protective measures built in to block out these strong signals.
Interference From Spurious Emissions
Radio towers unintentionally transmit weak signals on frequencies they are not supposed to be using. This signals known as ‘spurious emissions’ and can cause problems to your equipment. In this case the FCC requires those responsible to take action and stop the spurious emission from occurring again in order to prevent further interference in the area. If your garage door opener is experiencing interference it might be due to one of these sources or another source entirely. Fortunately there are some basic troubleshooting steps you can take to battle any type of interference with your garage door opener and hopefully resolve the issue quickly and effectively.
