I suspect that once the unit is not against a wall, then it will stop feeding back on itself and become less erratic.

Having a unit run for quite a long while after opening/closing such a large door is normal in the dry season (winter). Do you know what the ambient (room) RH is?
I don't know the room humidity, but it must be dry. The seal is in good shape. I'll try moving the unit & see what happens.

I'm not sure its 1000 count... I modeled it after one I saw on the internet (Ivy-Hall priceton or something).

I'll edit my humidor post with some details about it.

Thanks,
