Garage door when i close it it goes all the way down but then reopens all the way up then light starts blinking

SOURCE: Door will only close when held down

That normally happens when the sensors aren't aligned. Both sensors have led lights on them the yellow/orange one will stay on all the time the green one will go out if it cant see the other sensor. Possibly theres a wire that's broken or the other sensor is really out of alignment. Check every inch of wiring from the sensor to the opener, remove wire nuts if present and check the connections. The wires that are used are small, solid and can break easily. Also see if there's a staple that's too tight, move the wire abit where it's stapled and look for damage.

You need to do is shade the eyes some how for th door to work. What I did was remove them and put them up by the opener so the sun does not get to them.

SOURCE: garage door opener will not go down.

After reading the responses I went out and looked at the sensors, but this time instead of aligning up and down I moved the one sideways and WOOHOO! the remote works fine now.

Most likely your door sensors have been bumped and are not aligned properly. Make sure they are pointed at one another and the small light on each one is lit and not blinking.

SOURCE: Garage door closes then reopens (does not stay shut)

On the side of your opener you will find the down limit control. Using a small screwdriver turn this control in the opposite direction of the arrow printed on the cover. May take some tweaking to get it just right.
