Step by step
-
1 Shut off water and power
Close the supply valve (under the sink or behind the fridge), unplug the fridge, and pull it out for access.
-
2 Open the rear lower panel
The valve is where the 1/4" supply line enters, a small solenoid block with one inlet and one or two outlet tubes.
-
3 Disconnect lines and wires
Photo everything. Crack the supply fitting with a towel underneath, then release the outlet tubes (compression nuts or push fit collets, press the collar to release) and the wire plugs.
-
4 Swap the valve
Transfer the bracket, connect outlets and wiring per photos, and reconnect the supply line snug, not gorilla tight on plastic threads.
-
5 Leak watch before closing
Open the supply slowly, watch every joint for two full minutes, run the dispenser to purge air, then panel on and fridge back. Check again the next day.
