It sounds like something is interfering with the radio signal of the openers. If you look at the end of the openers where all those white wires go you will see a small light. It is normal for this to blink randomly but if it is blinking rapidly it is receiving a signal. Have you added anything electrical to your home or garage? Some of the oddest things will interfere. You might also remove the batteries from your remotes just in case one is stuck on.

I will need to check the light again. I did replace all batteries already. We did install a new refrigerator over the weekend. Could that be causing it? If so, what can I do?

Thanks for your suggestions!!

unplug the frig and see if the remotes work. If they do the frig is the problem . If they don't then it is something else. If it is the frig, I have no clue what to do.
