Why is my Sub-Zero making small or hollow ice cubes?

Low water pressure, often from a clogged filter or partially closed valve, is the usual cause. Replacing the filter and checking the supply often fixes it.

The ice maker in my West Charlotte rental fridge stopped after the unit was moved. Why?

Moving the refrigerator often kinks or pinches the thin supply line behind it, or the valve was turned off and never reopened. Check both with the fridge unplugged. If the water supply is fine, the inlet valve or ice maker may need testing on a visit booked by the owner.

My side-by-side dispenser hums but no ice comes out. What causes that?

Usually ice has melted and refrozen into a solid block that jams the auger, often after the door was left ajar or the power flickered. Empty the bucket and let it thaw. If it jams again soon, a door seal, fan or temperature issue is likely the cause.

Sub-Zero Ice Makers: What We Check First

Sub-Zero ice comes from two very different machines. Most refrigerators and freezers have an automatic ice maker inside the freezer compartment, fed by a water valve and line. Separately, Sub-Zero sells undercounter ice makers that produce clear ice in a dedicated cabinet, often installed in a bar, butler's pantry or outdoor kitchen. Undercounter units need a water supply, a drain, and either gravity drainage or a drain pump.

Clogged water filter or low pressure reducing ice production
Frozen fill line stopping the in-freezer ice maker
Scale buildup on undercounter ice maker evaporators
Drain pump or drain line clog in undercounter installations

The full explanation, including what you can safely check yourself and when repair beats replacement, is in our Sub-Zero ice maker repair guide.

Water Lines, Add-On Kits and Freezer Temperature

Many older top-freezer refrigerators in west-side homes had an ice maker kit added later, fed by a thin copper or plastic line through the back of the cabinet. That line can kink when the fridge is pushed back after cleaning, and old saddle valves on the supply pipe sometimes clog or start to drip. A freezer running too warm also stops ice production well before food starts to thaw. Side-by-side models in rentals and duplexes add a dispenser, where a frozen fill tube or a jammed auger often ends ice delivery.

Checks You Can Make Before We Arrive

Make sure the supply valve is open and the ice maker's arm or switch is in the on position, and replace the water filter if it is overdue. Unplug the fridge before breaking up fused cubes in the bucket. If ice still does not form, our technician tests the inlet valve, the ice maker module and the freezer temperature, then explains the cost before any repair. Tenants should contact their landlord first.
