Common Sub-Zero Ice Maker Problems (And How to Fix Them)

Introduction

Sub-Zero ice makers are built to last, but eventually they may stop producing ice, make small cubes, or leak. Below are the most common issues and what you can do.

🧊 1. Ice Maker Not Producing Ice

The most common reasons:

• Water line clogged

• Frozen fill tube

• Faulty water inlet valve

• Ice maker switch accidentally turned off

Quick fix:Check that the ice maker arm is down and the water line is not kinked.If still no ice, a technician needs to inspect the valve and fill system.

💧 2. Ice Maker Leaking Water

Leaks can occur from:

• Cracked water line

• Broken inlet valve

• Ice maker overfilling

• Water filter not seated properly

Leaks inside the freezer can also freeze and block airflow — which affects cooling.

❄️ 3. Ice Cubes Are Too Small

This means low water pressure.Common causes:

• Filter overdue for replacement

• Blocked water line

• Weak water valve

🧼 4. Ice Tastes or Smells Bad

Likely issues include:

• Dirty ice bin

• Old water filter

• Warm freezer temperature

Sub-Zero recommends changing the filter every 6–12 months.

🛠️ 5. Ice Maker Making Noise

Grinding, clicking, or buzzing noises can signal:

• Ice stuck in the motor

• Jammed auger

• Faulty motor gears

Avoid forcing anything — it could damage the unit.
