I actually fixed mine yesterday. On the main circuit board there is a quarter size black disc in the top right hand corner. This is a current limiter, it was cracked and discolored. I ordered it from Digi-Key Corp., the part# is 570-1062-ND, and costs a whole 2.42 each. I ordered 2 and with shipping they were 7.34. I soldered it in, put everything back together and I am generating chlorine!
