Well, as most things go with time, they tend to fail. One case is my Craftsman garage door opener.
Its been getting noisy over time but I didn't realize how much until it completely failed Monday morning. If I didn't look in the rearview mirror and saw darkness. Got out and I hear the motor running, but the door had only moved about 3".
Well, looks like I have problems, but I'm on the way to work, so lets open and close manually and have a look later.
Well, this is what I found when I got home.
The gear that is driven by the worm gear has eaten itself alive. Upon further research, this gear needs to be lubricated regularly, which it obviously has not been. I've lived here almost 4 years and I've only greased the rollers and lubed the chain.
So off to Sears service center I go. Well, guess what, Sears cannot help unless you have the model and serial number. This happened to me about 12 years ago at this same place. Why should it be different now? I get online on ebay, theres a seller there that has the gears. I call his #. He asks "Do you have the optical eye at the bottom of the door?" yes, I do. Then tells me "its the same gear from 1984 to today". Why can't sears figure that out?
I ordered the kit, it arrived in 3 days. My next post will illustrate replacement and chain adjustment.
