Have you been having problems lately with your garage door opener remotes, range of signal, and intermittent operation issues! We have recently learned that the new 5G cellphone signal from Verizon wireless, AT&T, and soon to follow T-Mobile is causing interference with older garage door openers. The issues range from garage doors not opening all the way to low range signal issues. All garage door openers work with radio frequencies which are susceptible to interference from external sources such as the new 5G cellphone signal. Newer garage door openers use tri-band technology or encrypted radio frequencies to communicate with remotes which offers better range and fewer interference issues. Unfortunately the cost of a new external radio receiver with remotes can range up to a couple hundred dollars with parts and labor. When you compare the cost of a new garage door opener versus putting money towards an older motor unit, its best to buy a new motor unit that will not have these issues. When it comes to technology and updates in software many of the household appliances we use will slowly need to be replaced. Our final piece of advice for people that have older garage door openers is to save up some money and replace the old unit with a new Liftmaster Garage Door Opener.
