I have an freestanding under-counter GE Monogram Ice Maker Model #ZDIS150WSS3 which started blowing the breaker in my main circuit breaker box. I pulled it out and plugged it into a GFI outlet. It ran all day making ice, so I plugged it back into the original outlet. It ran for a couple of hours making ice, then blew the breaker again. When I plugged it back into the GFI, it then blew the GFI outlet. There is some calcium like build up on the part attached to the back of the condenser, but all other wiring looks dry and fine. Any suggestions?
