I have a radon reduction system with a GFCI on the circuit before the fan. The GFCI is tripped and wont reset. When I press in the reset button and let it go, I see a small greenish spark (tiny) in one of the receptacles. All of the connections seems good. Should i try to replace the GFCI? I don't know whether there is a problem at the fan unit. Or just call an electrician.
