Garage Door Won't Close

While I'm on my how-tos I better add this one.  On Friday the garage door stopped closing with the remotes and would only close by holding down the button inside the garage until it totally closed.  I didn't know this until I left for the store on Saturday and had to call Larry from my car and tell him I couldn't get the door to close.  He was already aware of it, that's why I knew it stopped on Friday.
On our way to Unos for dinner Saturday night, after Larry pulled the car out of the garage, I held down the button in the garage to close the door and then went through the house to go out the front door, then I used my phone to look up our garage door problem.

After reading the solution, I remembered that we had this problem before so I thought I better put the solution here so I can find it again.

Problem:  Garage door opens fine with remotes but won't close unless button inside garage is held down until it closes.

Possible Cause:  The sensors aren't aligned or the wire needs a jiggle (may be a bigger problem here) and the door thinks something is blocking the door so as a safety precaution, it won't close.  Holding down the button in the garage overrides this safety feature.

Fix:  Line up the sensors by making sure a green light (at least for our door) is glowing on each one.
