How to Replace the Water Inlet Valve on a Samsung RF28R7351SG Refrigerator — Step-by-Step Instructions
Step-by-step instructions for the Samsung RF28R7351SG (french-door refrigerator, twin cooling). Parts and access points can differ slightly by production year — the steps below cover the common layout for this platform, and the model notes flag its quirks.
Unplug the fridge AND shut the water supply at the saddle/stop valve before disconnecting anything. The 1/4" line stays pressurized until the supply is off.
Tools
- Nut driver
- 1/4" line wrench or open-end wrench
- Towels
- Phone camera
Parts
- Dual (or triple) inlet valve for your model
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.
Samsung RF28R7351SG notes & error codes
Two magic tricks every owner should know: OF OF means demo mode (the fridge looks on but won’t cool — a button combo fixes it free), and any ice maker repair should cite Samsung’s service bulletin fix kit, because installing a bare replacement maker without the sealing kit just restarts the clock on the same failure.
| Code | What it means |
|---|---|
| 22 E / 22 C | Fridge fan error |
| 21 E | Freezer fan error |
| 5 E / 8 E | Sensor errors (fridge/ice room) |
| OF OF | Demo mode — cooling disabled, exit via button combo |
| 84 C | Compressor lock/current fault |
| 88 88 | Power glitch — reset power |
Full details for this machine — common problems, causes, and costs — are in the Samsung RF28R7351SG repair guide. The general version of these instructions is here.
If water still won’t flow with a new valve, the line is frozen inside the door or the control isn’t energizing the solenoid — both are quick professional diagnoses and slow DIY ones. If you'd rather skip it entirely, find a refrigerator repair pro near you →
