My GFCI circuit pops when I use my smoker. There’s nothing else plugged into the circuit.
Your smoker uses a low 750 watt heat output and low ampere consumption so tripping your GFIC circuit will be unlikely.
If the GFIC circuit pops, check the following:
• Check if the heating element has a rust spot, hole, etc. where moisture can get inside the heating element and trip the GFCI.
• Check the electrical connection access location on the back of the smoker.
• Check if the gaskets are in place to prevent water intrusion.
• Check if the electrical contacts are free of rust and are not damaged or loose (refer to your Manual, if needed.)
