[Varistor]

Hello, The problem is that the timer does not turn. I disconnected it, checked inside for faults, looks OK. Power wire is good to timer. Correct voltage at black/white(120V). Installed new ice maker kit. Same problem. Then reinstalled old one briefly and the timer/icelever moved for a moment. Some water started to fill, and then suddenly stopped after a trickle of water entered. Figured water is not frozen at valve. Very frustrated. Checked harness. Wiggled wires for possible shorts or bad connections. The new icemaker timer never budged! It's at the 2:00 position. Checked continuity at the harness/fuse---Did not do the t+h test, and what is the brown wire for, I guess the fill valve?? Please help, Thanks!
