I think they lump them all together now , but when the digital first came out the
Masterbuilt electric smoker was the analog and the MES (
Masterbuilt electric smokehouse ) was the digital .
That's how they kept them identified for warranties , operation and parts .
Just FYI . Refer to an MES and the old guys know what you have .
Anyway , as stated in a couple posts above I would say your problem is condensation and bad smoke .
Already been said , but no water in the pan .
If your currently dumping wood chips in the tray , you should clean the ash out of the tray during a long smoke . The ash an cause the new chips to not fully burn and put out dirty smoke .
