Why ice makers fail in New Ulm
Brown County water carries a substantial mineral load, and many households outside the city core are on wells with more still. Every cycle pushes that water through a small solenoid valve with a fine inlet screen, and the scale accumulates there first. A narrowed valve underfills the mold, which produces hollow shells, undersized cubes, or crescent slivers — a gradual decline rather than a sudden stop, which is why people usually live with it for months before calling.
As flow slows, the fill tube becomes the next casualty. The tail of each fill lingers instead of clearing, freezes in the tube, and the following cycle pushes water against the plug and out down the compartment wall. The sheet of ice on the freezer floor is the visible result, and it is the symptom most New Ulm callers describe first.
The third factor is age. New Ulm's installed base skews older than the metro's, which means more freezer-mounted modules with mechanical ejectors and internal thermostats. That is a simple, repairable design: the module, the valve, and the fill tube cover nearly every failure, and all three are parts we can identify in advance from your model number and bring down Highway 14 with us.
