I’m glad to have found this thread.


I removed the front control board and powered things back up.

My BOV845 is buzzing loudly from the front temperature control knob. When i turn the knob, the buzzing changes a bit.  I’m thinking that maybe it’s not the switches but the rotating (pots?). Has anyone tried to replace those? Its very weird to me that i’m hearing buzzing from them, seems to suggest a short of some sort, and a lot of current passing through!?
