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.

Do you service undercounter ice machines in south Charlotte homes?

Yes. We repair residential undercounter ice makers along with refrigerator ice makers. Common fixes include water valves, drain pumps and thermistors, and a thorough cleaning sometimes restores production on its own.

Our Ballantyne fridge makes ice but the dispenser jams. What is wrong?

Ice that clumps in the bin from humid air or infrequent use is a common cause, and so is a worn auger motor. Empty the bin, break up any clumps and try again. If the motor hums without turning, it likely needs repair.

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.

Door Dispensers and Undercounter Ice Machines

In Ballantyne homes, ice usually comes from one of two places: the in-door dispenser on a French-door or side-by-side refrigerator, or a dedicated undercounter ice machine in a kitchen island, wet bar or bonus room. They fail in different ways, so mention which one you have when you book.

Refrigerator ice makers commonly stop because of a frozen fill tube, a failing inlet valve, a clogged water filter or a jammed auger in the door bin. Undercounter machines need regular cleaning, and scale or slime on the evaporator plate slows production and leaves cloudy or misshapen ice. Municipal water here is treated, but filters still need changing on schedule.

Safe checks include replacing an overdue filter, making sure the shutoff arm or switch is in the on position, and confirming the supply valve behind the unit is open. The technician tests the valve, mold heater, sensors and drain, then explains the repair and price before starting.
