Troubleshooting Sub-Zero Refrigerator Ice Maker Malfunctions
A Sub-Zero refrigerator is a premium appliance designed for superior performance, but like any high-end machine, its ice maker can experience issues over time. A malfunctioning ice maker can be frustrating, especially in Scottsdale’s hot climate, where having a steady supply of ice is essential. In this guide, we’ll explore common Sub-Zero ice maker problems, their possible causes, and how to fix them.
Common Sub-Zero Ice Maker Issues & Solutions
1. Ice Maker Not Producing Ice
Possible Causes:
- The ice maker is turned off.
- The water supply line is clogged or disconnected.
- The water filter is clogged, restricting water flow.
- The freezer temperature is too high.
Solutions:
- Ensure the ice maker is switched on (check the control panel or the lever inside the ice bin).
- Verify the water line is connected and not kinked or blocked.
- Replace the water filter if it hasn’t been changed in the last 6 months.

2. Ice Maker Producing Small or Misshapen Ice
Possible Causes:

Solutions:
