Hi all. New guy here. Just found this site and it is an absolute wealth of information! Thanks to everyone for their contributions! Just fired up my old 20070106 and after a minute or so, it pops the ground fault adapter. Thought it might be a weak adapter so I tried another circuit and got the same results. Don't quite understand what is happening. If it were a solid short in the smoker the adapter should trip immediately, not after a minute or two. Anyone else had this happen or know what the issue may be? Thanks in advance for any input. Doesn't sound like Masterbuilt CS would be much help from reading other posts here, but probably will call them anyway.
