Here is a partial list of all the ways you can maximize the fun of replacing a garage door opener.
First, order the exact same model as you are replacing because you think you can just bolt the motor unit in place and be done in less than five minutes. That won't work, because the design will have changed just enough to make the new unit incompatible. Of course you could have simply replaced the faulty circuit board in the old opener, but that would have cost $80, which is far less than a whole new opener, but too much money for one little board. So yes, definitely stick to the higher ground and buy the whole kit and kaboodle.
Be sure not to read the instructions that say you have to put the rounded bolts on one side the track, and the flat bolts on the other. And please do NOT pay any heed to the warnings about removing that plastic tie wrap on the gear, because what harm could that do...unless perhaps it allowed you to rotate the chain and get the entire system out of whack so that the motor was trying to open a door that was already open. Finally, be absolutely sure that you do NOT check that the chain is on the sprocket before bolting the motor and track back into place. This way you'll get to take the entire shabang back down again to thread and tighten the chain after you just spent 20 minutes getting it bolted in place.
I you are careful to follow all of the steps above in just the right order, you can make what would have been a thirty minute job into an entire day of installing, uninstalling, installing, uninstalling, and finally collapsing in exhaustion.
One final hint: if you have been typing for five minutes on a post as I have, and then by some inexplicable combination of keystrokes manage to highlight everything you've typed and delete it in one stroke, try Control-Z. That much, to my amazement, worked.
