Harmen P68 whistles 60% of the time with feed auger running??

[clayton]

I have a P68 and have used 25 bags, end last yr and this... the pellets ran out last night and just before the stove "whistles" when the auger motor runs. About 60% of the time it runs just after it starts up... I thought it was an air leak / whistle but I could not find any. Might be a vibration or ?? Any ideas??

thanks for helping...

how old is your stove? i,e, what year was it made?

Give it a shot of graphite , add it to the corn as it goes to the auger, should quite it down.
