According to the schematic, my wires are hooked up correctly. However, once it reaches a certain temperature, it trips my GFI in my workshop. It doesn't trip my breaker, but the GFI. The thermostat in this thing is very rudimentary. It's basically a cover with 2 screws on top, and inside are two pieces of metal. 1 is V shaped and attached on both sides, and the other is just a flat piece attached on one end. I have a feeling the thermostat is bad, but have no idea if I can test it before I order a new thermostat.
Any thoughts or suggestions?
Thanks in advance,
