Hiya All,
Well I've gone and done it. The garage door opener was making a heck of
a racket (along with the door itself). Seemed to me that
it was time for a bit of grease. This is a screw drive opener. I
greased the screw and the track on the doors. Well it worked. The
door opener won't work now. Push the button and it makes a bit of noise
and stops. There are no obstructions in the door's path and
the sensors indicate the door should move. So I have a couple of
questions. 1. Seems odd, but did I hose the thing up by greasing the
screw? 2. Any recommendations for either fixing it or replacing it
(ie. Brand, screw vs. chain, etc....).

Thanks for the advice. I will probably be forced into replacing it this
weekend as the wife puts her car in the garage and well, she probably
can't lift the door on her own. Anyway, thanks,
cc


What type of grease did you use? Grease on a leadscrew will increase the
motor current if excessive. This will then cause sensitivity setting to
trip. Wipe all the grease off and clean with alcohol, then apply whatever is
recommended on the screw...I think someone posted white lithium grease. That
should solve your problem. I know on machine tools we would measure the
motor current to test leadscrews and when the techs put too much grease on
them they might go from 2 amps up to 6 or more !! So there's my .02 and hope
it helps.....Ross
