Is your Garage Door Stuck Open?
I’ve had fun lately as the door on my garage has been opening and freezing up all by itself. Luckily, I read enough so I had a clue. I had heard that the radio frequency commonly used by automatic garage door openers wasn’t officially allocated to opener companies. It was actually assigned to the US Army in 1950.
Apparently, I’m not alone. While the military hasn’t been using the 380–399 megahertz frequency, it will be used by new homeland security radios being allocated to 125 bases between now and 2008. The estimated 50 million affected garage door openers make up about 90% of the installed base. The FCC allows military frequencies to be used by low power devices as long as they don’t cause interference. Obviously, this wasn’t a problem when the military wasn’t using the frequencies.
So if your garage door starts acting strange don’t be surprised. Before you run out to purchase a new unit you should be able to adjust your remote frequency slightly to fix the problem.
