If the freezer is cold but the ice bin stays empty, the ice maker - not the sealed system - is usually the suspect. Leesburg homeowners see this after a power blip, a water filter that was never changed, or a vacation when the ice maker sat unused and the fill tube froze.
Moderately hard town water leaves scale in the inlet valve. The valve then dribbles or will not open, so the mold never fills. Optical sensors on some Samsung and LG French-door units also stop harvest when the bucket looks “full” to a dirty emitter, even when it is empty.
Checks before you call
- Ice maker arm or switch in the on position
- Water dispenser still works (if equipped)
- Filter age - six months is a common interval, sooner if ice tastes off
- Freezer temperature near 0°F; a warm freezer will not harvest
What contractors typically test
Water at the saddle valve, continuity through the ice maker module, and whether the mold heater and ejector complete a cycle. On door-ice models they also check the ice room fan and the passage into the bucket. Related work includes valve replacement and defrosting a frozen fill tube.
Neighborhood notes
Builder kitchens in Potomac Station and Tavistock Farms often use Whirlpool-family ice maker assemblies that swap as a module. River Creek built-ins may need a longer diagnostic because the ice system is integrated into a cabineted refrigerator.
