Toterhome,
The solenoid on the RM1350 is on the back of the frig. Go outside and remove the lower louver panel and the solenoid will be right in the middle.
If you also have a water dispenser, the solenoid is a dual unit with the ice maker coil operated on 110V and the water dispenser on 12V. Careful not to get the wires swapped.
I've attached a picture of my solenoid and the wiring diagram. On the wiring diagram, the solenoid is at the bottom left.
