Craftsman Garage Door Opener Problem

LomanSMOctober 20, 2013

Hey all,
I'm having trouble with my Craftsman 1/2 HP garage door opened. I recently replaced the drive sprocket and now the carriage will stop after just a few inches either way. The limiters aren't the problem and the force adjusters don't seem to help.

Anyone have any ideas?

A couple thoughts.

This just started happening since you replaced the sprocket? Is it possible the chain is now too tight, or mis-aligned? The sprocket has the same number of teeth?

Also, I think many people make the mistake of assuming their opener is defective, when in fact it's the door tracks or springs. With the opener disconnected, does the door open and close easily throughout its range? If not, it could be over-stressing the opener and causing it to stall, regardless of how high the force adjusters are set.
