Belt Noise for Chamberlain HD600 1/2 HP Whisper Drive Garage Door Opener
Recently installed this Whisper Drive HD600 Chamberlain garage door opener and everything has been working great. However, over the last month when we either open or close the opener, the belt squeeks and squeels which is quite annoying. In looking at the installation manual, everything was done properly and the manual indicates no maintenance is needed on the drive iteself. Is there something we can do to eliminate this noise?
