Liftmaster 3800LM Residential Jackshaft Opener
What't the current feeling about the Liftmaster 3800LM residential jackshaft garage door openers?
I was planning to install them on my new garage, but was warned by someone who should be in the loop that people were having problems with them, especially with heavier doors.
I have done several web searches without finding many negative postings about them, so the warning came as a surprise. Has anyone here had any bad experiences with these units?
