the ground fault, L1 cant be grounded, but the heater element must be grouded.
im saying that because if L1 was grounded out, the dead short would trip the breaker.
so, the relay is closed, heater 3, either the limit is stuck open or the heater is o/c. Heat 2 is fine, and heat 1, the element is grounded out, and not connected to L1.
We will find out tomorrow.
on a separate note, do the elements on these things go o/c often?
I think I might have a spare, so it might just get swapped out, but either way, ill find exactly whats happening tomorrow.
