Start with a thorough visual inspection of wires to make sure that there is no rubbed/melted insulation on any wires.
If you need more fuses ASAP to complete the test, you can purchase 3-5 AMP fuses from local hardware stores. You may also order fuses on our website here.
Fuses are typically found on the back of the controller in one of two locations. Either in a grey box with a lid (may have an additional fuse zip-tied to it) or in a black tube with a screw-on cap.
Note: D2 grills do not have fuses.
A GFCI will trip if the circuit is overloaded, no matter if it is AC or D2. BUT - a D2 grill can trip a GFCI if there is a short in the power supply.
