A lady called asking us to come out and tighten the roller chain on her old garage door motor. Over the phone I explained that rarely the chain gets loose and most likely the sprocket is wearing out and needs replacement. Upon arrival we saw the garage door opener was a Stanley, and being out of the garage door business, replacement parts are no longer available. After climbing the ladder and inspecting the problem, we noticed the rail is connected to a scru which is adjustable. This scru tightens the chain. After closer inspection we noticed the chain had fallen off the front pulley and needed to be put back on. After properly tightening the chain, and putting the chain back on the pulley the garage door opener was successfully repaired.
