What We Fix
An ice maker is a small refrigeration system with a plumbing problem attached, and both halves have to work. Boulder's mineral-rich water is hard on ice equipment: scale builds on the evaporator plate, narrows the fill path, and slowly starves the harvest. We repair built-in refrigerator ice makers and dedicated ice machines alike.
- Built-in refrigerator ice makers and dispensers
- Standalone clear-ice and nugget machines (Scotsman and comparable)
- Water inlet valves, supply lines, and filter housings
- Harvest modules, thermostats, and ejector assemblies
- Water pumps and distribution tubes on clear-ice machines
- Evaporator plate descaling and hard-water cleaning
- Drain pumps and float switches on gravity and pumped drains
Common Problems We See
- No ice at all. A closed inlet valve, a frozen line, or a module that never calls for a fill.
- Ice bin freezes into a block. A leaking valve dribbling water, or a harvest that stalls part-way.
- Hollow or cloudy cubes. Low fill volume or scale on the plate on a clear-ice unit.
- Small or slow production. Scale-choked water path or a weak pump.
- Water on the floor. A cracked line, an overflowing bin, or a blocked drain.
Typical Causes
Most no-ice calls are a water-delivery problem, not a dead compressor. A water inlet valve that will not open fully, a saddle-valve or filter clogged with sediment, or a line frozen where it runs cold will all leave the machine cycling with nothing to freeze. On clear-ice machines the culprit is often scale: Boulder's hardness plates out on the evaporator and in the pump until harvests turn hollow and cloudy. We test water pressure and volume at the valve, inspect the plate, and descale as part of the repair so the fix lasts.
Brands We Service
We service ice makers built into Sub-Zero refrigeration and standalone machines from Scotsman, True Residential, Thermador, and other high-end lines. See the full brands list.
Symptom Reference
| Symptom | Likely Cause | What We Do |
|---|---|---|
| No ice, no water fill | Failed inlet valve or frozen line | Test valve, thaw line, verify supply pressure |
| Bin frozen solid | Leaking valve or stalled harvest | Replace valve, test module and thermostat |
| Hollow or cloudy cubes | Low fill or scaled evaporator plate | Descale plate, correct fill, replace filter |
| Slow or small production | Scale in water path or weak pump | Descale, test pump, replace if failed |
| Water leaking out | Cracked line or blocked drain | Replace line, clear drain, test float switch |
