Problem: Water valve circuit fault – solenoid not activating or drawing incorrect current
How to Fix Refrigerator Error
- Unplug refrigerator and turn off household water supply to unit.
- Remove rear access panel to access water inlet valve assembly (typically near bottom rear).
- Locate dual water valve assembly with separate solenoids for dispenser and ice maker.
- Disconnect wiring harness from valve assembly.
- Measure resistance across each solenoid coil (should read 300-500 ohms).
- If resistance is infinite (open circuit) or zero (shorted), solenoid has failed.
- Verify 120V AC reaches solenoid connector during dispenser activation or ice maker harvest cycle.
- Inspect valve body for mineral buildup restricting water flow (remove inlet screen and clean).
- Check water supply pressure – must be minimum 20 PSI for proper valve operation.
- If solenoid resistance is out of range or valve doesn’t open with power applied, replace water inlet valve assembly WPW
Still Not Working?
If the replacement part didn’t fix the issue, you may have a wiring problem or main board failure.
