Hi all, I have a Masterbuilt Model #20071914 that I have used maybe 10 times. The last time I used it, the circuit breaker would trip EVERY time the box reached the set point temperature (225) and turned off the element. I would reset the breaker, turn the smoker back on, and all would be fine UNTIL it reached set point temperature, then the breaker would trip again. I tried different circuits around the house and all of them did the same thing. Any advice on what to do? Note my house has arc fault breakers, not ground fault outlets. I don't think that matters here because they have never tripped in 6 years and the smoker worked fine for a while. Thanks!
