I am super pleased with my new washer and dryer BUT the dryer is loud and I am trying to find out if this is normal.  When in operation is makes a loud high pitched sound.  I have gotten rotten support from LG.  I have been trying to just get anyone to listen to it...I just want to know if it is a normal sound.  I can live with it but if it isn't operating normally I would like to know.  After spending all morning on the phone I was met with dismissive condescension.  All I wanted was to speak with an actual repair/installer from LG to let me know if it was a normal sound.
