A dedicated ice maker is a fixture in Evergreen entertaining kitchens and wet bars, and when it stops it is usually noticed right before a full house arrives. Whether it is the ice module in a Sub-Zero built-in or a standalone clear-ice machine, the fault is almost always in a small, serviceable part rather than the whole unit.
We trace ice problems through the water path first, then the freeze and harvest cycle, then the sealed system on standalone machines. You get a written estimate before any work, genuine OEM parts, and a full harvest cycle run before we leave so you can see it working.
What We Fix
- Water inlet valves and blocked or frozen supply lines
- Harvest and eject mechanisms that stall mid-cycle
- Thermistors and control boards in the ice module
- Pumps and reservoirs on clear-ice machines
- Sealed-system faults on dedicated ice makers
- Scaled water paths and drain lines
Common Problems We See
- No ice at all, with the bin sitting empty
- Low output that cannot keep up with use
- Cloudy, small or hollow cubes
- Water leaking under or behind the unit
- Ice with an off taste from a scaled or old filter
- A machine that cycles but never drops ice
Typical Causes
No ice usually starts at the water supply: a line frozen against an exterior wall, a shutoff that was never fully opened, or a weak inlet valve. Low or cloudy ice more often points to a scaled water path or a freeze cycle that is not completing. Hard water in the high country accelerates scale, so a filter change and a cleaning are frequently part of a lasting fix. On standalone clear-ice machines, a warm or leaking unit can also mean a sealed-system fault, which we leak-test before quoting.
| Symptom | Likely Cause | What the Fix Involves |
|---|---|---|
| No ice, empty bin | Water valve or frozen line | Thaw and reroute the line, replace the valve |
| Low output | Weak flow or freeze fault | Restore flow, test the freeze cycle and sensor |
| Cloudy or small cubes | Scale or old filter | Descale the water path, replace the filter |
| Leaking water | Cracked line or drain block | Replace the line, clear the drain |
Quick Checks First
Confirm the water shutoff is fully open, check that the line is not kinked or frozen where it runs along a cold wall, and replace a filter that is past its interval. If ice stops after that, it usually points us straight to the valve or module.
Out of Ice Before a Full House?
Book a diagnosis and we will trace the fault through the water path and the module. Diagnostic and travel fees, if applicable, are confirmed before the appointment and before repair approval.
