Okay...upon further inspection, my left spring has broken in two. Going to call around for some quotes to replace the spring. Thanks for the suggestions.

Well sounds like its a pressure setting. you said you open the door by hand? Was it easy to do? Ask your self this can a 15 year old kid open it and close it? If so then it sounds like its a presure setting There should be two blue slots on your opener with numbers 1-9 says up and down force. Turn the up force towards the bigger number. Just a little bit. But before you do that as the other guy stated make sure that your cables and springs are working. Spring depending on your doors can be in three places but we going to assume you has the most common set up so look over the top of your door (with it closed) you should eb able to see a tube running across there. and somewhere in the in middle a set of spring look at the spring to make sure that you dont see any of the tube showing in the springs. Becare not to touch the spring as they are under a lot of stress.

SOURCE: Garage door won't close.
After replacing the worm gear and main drive gear on my Craftsman 1/2 HP garage door opener I found that my door moved about 4 inches stopped and reversed the same distance. I checked all the settings and everything seems OK. What fixed the problem was I released the two allen set screws on the end of the motor shaft and pulled tha motor shaft toward me. When I replaced the black plastic cap that looks like a pill cap top on the end of the shaft this corrected the depth setting that cap rotated through the RPM sensor. I set the limit settings (up and down) on the side of the opener and reset the force pots marked (KC) to mid range.
the door now works. I hope this helps. I also checked and eliminated the door sensors by putting a box in the beem this inhibited any movemnet at all, so I knew it wasn't the door sensors as there was at least 4 incheds of movement prior to the box and nothing with the box.

Make sure the door sensors are aligned properly. They must be pointed at one another and the small light on each one should be lit and not flickering.

The LED flashing 3 times is the code for a bad wall control. You can easily verify this by removing the wire from terminal 1 on the rear of the motor unit. If your remote and keypad start working you will know the wall control is bad.
