Hi all, I have a masterbuilt electric smoker model #20071917 that I have used probably 10 times. The problem I'm having is when the box reaches temperature and the element shuts off, it is tripping the circuit breaker. It works fine as long as the element is on, but the instant the box reaches temperature (225 for example) and the red light goes out, the circuit breaker trips. I have tried multiple different circuits with the same result. Any advice on what to do to fix this? Note my house has arc fault circuit breakers, not ground fault outlets. I don't think that matters here, because they have never tripped in the past 6 years, and the smoker worked fine for the first 8-10 times I used it. Thanks!
