Sub-Zero Refrigerator Error Code SERVICE + ICE

SERVICE + ICE means the control board detected that the water inlet valve was energized for more than 15 seconds during an icemaking cycle, or that power to the icemaker system was interrupted. The refrigerator shuts down icemaking to prevent a potential overflow or component damage. The most common causes are a jammed ice cube, low water pressure, or a faulty water inlet valve.

Yes, the refrigerator and freezer compartments will continue to cool normally when SERVICE + ICE is active. Only the icemaker system is affected by this fault. You can use the unit for food storage while you troubleshoot the icemaker, but do not ignore the code long-term, as a water inlet valve stuck in the open position could eventually cause water to overflow into the freezer.

The code will not always clear automatically. After resolving the underlying issue, you may need to manually reset the icemaker by pressing and holding the icemaker on/off button or cycling power to the unit at the circuit breaker for 30 seconds. Consult your specific model's owner manual for the exact reset procedure, as steps vary slightly across Sub-Zero product lines.

Start by checking the icemaker tray and bin for any ice that is jammed in the ejector mechanism and clearing it by hand. Next, verify your home water supply pressure is between 20 and 100 PSI using a gauge at the supply line. Check that the icemaker is level using a bubble level on the unit itself. If all of those check out, inspect the water inlet valve for visible damage or debris blocking the inlet screen. A failed valve will need to be replaced with a Sub-Zero compatible part.

If the cause is a jammed cube or a water pressure adjustment, the fix costs nothing beyond your time. If the water inlet valve has failed, the part typically costs between $50 and $150 depending on the model, plus labor if you hire a technician. Sub-Zero service technicians generally charge $100 to $200 per hour, so a valve replacement can run $200 to $400 total when professionally repaired. DIY replacement is feasible for homeowners comfortable with basic appliance repair, as the valve is accessible and the job requires only standard hand tools.
