The ice maker is not making ice, but the water dispenser works normally.

Safety first: Turn off the power and water supply before working on the ice maker.

Step 1 – Check ice bin and sensor

• Ensure the ice bin is properly installed and not overfilled.
• Clean any ice buildup from the ice level sensor or shutoff arm area.

Step 2 – Inspect fill tube

• Locate the ice maker fill tube at the back of the ice maker.
• If it is blocked with ice, thaw it with a hair dryer on a low setting and check for slow leaks that might refreeze.

Step 3 – Force cycle the ice maker

• Some Sub-Zero ice makers can be manually cycled via a test button or jumper; consult the technical sheet.
• If the ice maker does not move through a harvest cycle, replace the ice maker assembly.

Step 4 – Test ice maker valve coil

• At the dual water inlet valve, test the resistance of the ice maker coil and compare it to the specifications.
• If it is open or out of range, replace the valve.
