The other day it made a funny
noise and wont move the chain at all to put the door down or up


Check for worn plastic gears in the unit. Also, confirm whether correct
springs were used for offsetting the weight of the door. With the drive
disconnected via the "pulldown disconnect", very little force should be
required to open the door. Similarly, the unit should see very little
load when operating, otherwise, accelerated wear takes place. Homedepot
(if you're in the US) sells springs if it's necessary to repalce them.
