I measured in ohms. Did the same on the little cord as well. Cord is fine. I also cleaned the connections of the cord. I phoned the temp sensor too, it has continuity.
One thing I did notice, my circuit box inside the puck feeder was blinking. It wasn't a steady blink. It was blink, fast double blink, blink, blink. Not sure if this is a error code or not. I'll phone the service center on Monday.
