My GE Monogram Gas Stove started clicking the other day, even though it was completely turned off. Eventually it stopped clicking but the light would not turn off on one of the burners. its possible that a little bit of water somehow got in somewhere it shouldnt have. Now it does not work at all

Is there any way I can find out what exaclty went wrong with it, and how I can go about fixing it without calling a $$$ Repair man??

Thanks in advance.
