An ice maker that quits producing, drops hollow cubes, or freezes solid is a frequent request in Ridgewood kitchens, where built-in and gourmet ice machines get heavy use. The fault usually comes back to water supply, the freeze-and-harvest cycle, or scale.
Notes by Brand
The same symptom can have different causes depending on the brand. Here is how we approach ice maker not working across the roster.
Sub-Zero
We check the fill tube for a freeze-up first, then the inlet valve and the module. UC ice drawers and built-in makers share these failure points.
Scotsman
Scale leads the list. A lit cleaning light means it is time to descale. We run a full cleaning cycle and confirm water pressure.
Wolf
Wolf does not build ice machines, so a call here means a paired Sub-Zero or a separate unit, which we diagnose directly.
Kitchenaid
We test the fill tube, the inlet valve, and the optics. Small or hollow cubes point to low water flow or a partial freeze-up.
Thermador
We check the inlet valve, the fill level, and the harvest cycle. Built-in makers slow from scale in hard-water areas.
True Residential
We verify water supply and the harvest cycle. Gourmet ice modules respond well to regular descaling.
Viking
We check the inlet valve, the fill tube, and the module. A frozen fill tube stops production outright.

Indications and What We Check
| Symptom | Likely Cause | What We Check |
|---|---|---|
| No water | A frozen fill tube or a failed inlet valve | Thaw and clear the tube, test the valve and pressure |
| Small or hollow cubes | Low water flow or scale | Check the pressure and descale the unit |
| Cleaning light | A descale reminder is active | Run a full cleaning cycle and reset |
