Someone Has Pulled The Cord Switch
Your garage door opener should have a dangling red string known as the safety cord. When you pull this, it disconnects the garage door from the opener, which lets you open and close the garage door manually during power outages and other events. Theres a chance someone in your household pulled the cord switch without your knowledge. Or, you may have forgotten you gave it a pull earlier in the day. No worries! It happens to us all.
The cord switch has two settings pulled away from the opener for disconnection, and pulled toward the opener for connection. Try pulling the cord toward the opener first, as this should reconnect a detached cord switch. Then, try using your remote to close the garage door. If this solves your issue, your problem was a disconnected cord switch. If not, you may have a more severe issue on your hands involving your garage door opener.
