[Shop-talk] Garage Door Openers

[Steven Trovato]

Is there more to this story?  Did you just install them?  It seems 
odd that three openers would all spontaneously have the exact same 
symptom.  One thing that sometimes happens around here (NY) when it 
gets really cold,  the frozen ground rises a bit and causes the type 
of symptom you're talking about.  On my Sears/Chamberlain openers, 
there are screw adjuster things on the side of the unit for the upper 
and lower limits.  I assume yours has something similar.  Hopefully 
that manual will answer it all for you.
