The new opener was installed yesterday and today for a while it wouldn't close properly. The customer service representative said they will probably have to reverse the sensors. However, no one could come out today (Friday) or tomorrow. She will call me by Tuesday of next week to schedule someone to come here. The customer service rep. and the technician were nice but as of now, my new garage opener is not working to my satisfaction.
You'll never ask yourself that question again. Just look at your phone to know for sure. Most smart garage door openers will tell you if it's open or shut. They'll send a message every time your garage door is opened or closed too, if you like. Electric garage door openers provide a huge amount of convenience and safety. Imagine you're in a hurry, it's raining out, you pull out of the garage then press the button on your garage door opener remote. The garage door closes, and you didn't have to get out of your car.
