I don't have the service manual on this fridge but the two white quick connect are for the ice maker and the water dispenser. The hoses are two different sizes.
The terminals on the wiring connection for the ice maker and the water dispenser valves are different too. Look on the wiring diagram to see which coil is which.
Your wiring diagram if not on the back of the fridge should be under the fridge behind the kick plate.
There may be other information there also. |
