A constant harmonic

[Blu3bird]

My Hammond B3 now produce a constant harmonic (note C) when ever I pull out the Bass draw bar past 3. Unfortunately, the C harmonic is loud enough to hear even when playing in other keys--gives a very dissonant sound. How can I stop the sound of the harmonic (or dominant overtone) from sounding?

When you say the "bass drawbar", do you mean a pedal drawbar? If so, pull out your pedalboard to see of a pusher spring is bent and the note therefore partially sticking. You may need to adjust the leaf springs slightly.

Thanks Enor. Yes it is the Bass drawbar in the center of the organ. I will pull out the peddalboard and check out the pusher spring (what ever that is). I have never worked on this organ before; so, it will be a new experience. By the way, any youtube videos or Hammond organ repair?
