Harman XXV making a faint whistling sound

[Donn Fletcher]

Hi folks, wondering if anyone has had this issue with their Harman. Today my stove is emitting a real faint audible sound. It sounds like when you go for a hearing test and you Hear the real faint sounds. Most likely coming from the stoves mother board. Anyone else ever get that.

Try opening and closing your hopper lid.My harman did that so I had to replace hopper lid gasket...
