I have a 2016 Big Horn 3760 EL. For the last couple of days I have been periodically getting a loud buzzing sound coming from the area of the refrigerator. It lasts for about 5 seconds, So it is a little hard to isolate exactly what is going on. The buzzing almost sounds like an alarm of some sort; however, there is nothing in this area that would give off an alarm. Has anyone else experienced this, or have any idea what this song maybe?
