Been a while, but I have a problem I cannot figure out for the life of me. I have a new Harman P43 and lately it has been making a high pitch hissing sound. Almost sounds like it is letting off steam, usually when I shut it down. I know it is not the auger because that is not moving when it makes the sound and it almost sounds like it is coming from the back part of the stove. This stove is going to put me in a grave, I just got rid of a squeaking sound from the auger. I also have a Harman advance (12 years old) and all I have done to that is clean it. Any suggestions would be greatly appreciated.
Thanks
