Thanks guys. I have a legacy by overhead door. I feel like its bad sensor. I have it do this before but never had problem fixing it. One more question. How compatiable are the sensors do they have to be same ones.

My Overhad door garage door starts down and then goes right back up. Ihave done all te usual stuff. Nothing in the way sensor aligned. I can hold the button down and close it if I stop before it hits bottom. I have one solid green light and one blinking red. The power went off for short time...
