Sub-Zero Ice Maker Repair
Ice makers fail in patterns — fill, freeze, harvest, or the water supply feeding all three. We test the valve and inlet pressure, the module and its thermostat, the bin sensor, and the filter and line work that so often causes the problem in the first place.
Word for word
What gets described on the phone
- Ice maker filling with water but never harvesting a cube
- Small, cloudy cubes appearing after a water filter change
- Grinding or knocking from the bin auger
- The ice maker switching itself off and needing a reset every week
Fill, freeze, harvest, and the water that feeds all three.
On the visit
What is actually measured
- Inlet valve operation and supply pressure at the connection
- A full cycle timed through fill, freeze and harvest
- Bin sensor behaviour with the bin full and with it empty
- Filter age, plus the state of the line and any shut-off behind the unit
Cost
The bands this work falls into
Three things set the figure: which component failed, whether the part is on the van or has to be ordered for the platform, and how much has to come apart to reach it. A fan motor behind an interior panel and a sealed-system repair in the same cabinet are not remotely the same job, so what follows is a range and your number is quoted after the diagnosis.
| Repair | Range |
|---|---|
| Door gasket or seal replacement | $300–$730 |
| Evaporator or condenser fan motor | $300–$620 |
| Defrost heater, thermostat or sensor | $280–$670 |
| Ice maker, water valve or supply line | $300–$690 |
| Electronic control board | $520–$860 |
| Compressor or sealed-system repair | $940–$2,150 |
Flat $95 service call covering the visit and full diagnosis, credited against the repair once you approve it.
A like-for-like replacement is the other half of that decision: a new built-in of this class runs $8,660–$19,630 for the appliance alone, before delivery, panels, cabinetry or the fitting itself. That is the comparison worth making before a control board is written off as too expensive.

Production dropped to almost nothing across the summer. The condenser was matted with pet hair and the reservoir sensor had scaled up. Cleaned and descaled, and he pointed out the filter interval printed on the label.

It filled with water and then never harvested. The module thermostat had failed and the inlet screen was partly blocked. Both dealt with in one visit, and he checked the shut off valve under the sink while he was here.

The unit had stopped filling at all. It turned out the old saddle valve on the basement line had closed itself up over the years. He fitted a proper valve, ran new tubing and tidied the old line away.
