Home › Ice Maker Repair
If your ice maker has slowed down, stopped making ice, or started turning out cloudy or hollow cubes, the cause in a lot of Terre Haute homes isn't a dead machine — it's what's coming through the line that feeds it. Indiana American Water's 2025 Consumer Confidence Report for the Terre Haute system lists local water hardness at an average of 330 parts per million, ranging 280–400 ppm across the system, which the utility itself describes as naturally occurring. Anything above 180 mg/L counts as "very hard" on the standard hardness scale, so Terre Haute sits well inside that band (read the report). One call connects you with an independent local appliance technician who can look at the actual symptom before anyone assumes the ice maker itself is bad.

Most ice maker calls fall into a handful of patterns — here's what each usually points to.
The water supply line, the inlet valve, or the control module are the usual suspects — a technician checks whether water is reaching the unit before assuming a part has failed.
Undersized or cloudy cubes often trace back to mineral buildup inside the fill tube or valve — a pattern that shows up more often in hard-water systems like Terre Haute's than in areas with softer supply water.
An old water filter, a line that's sat unused, or mineral content in the supply water can all affect taste — worth checking the filter's age before blaming the ice maker itself.
A line that's kinked, poorly insulated where it runs through an unheated space, or scaled down by years of hard water can slow or stop the flow of water enough to halt ice production.
This usually points to a cracked line, a loose fitting, or a clogged drain rather than the ice maker itself — worth having looked at quickly, since standing water can damage flooring.
Clicking on a normal fill cycle is expected; a grinding or buzzing that wasn't there before can mean the ice maker's motor or module is struggling, sometimes because of mineral buildup on moving parts.
Having the refrigerator's brand and model number ready — usually on a sticker inside the fridge — helps the technician bring the right part on the first visit instead of a second trip.
The technician traces the line from the shutoff valve to the ice maker, checking for kinks, freezing, and — given the local water — mineral buildup at the valve and fill tube.
Inlet valve, control module, thermostat, and switches get tested individually. This is where a technician separates a simple part failure from a bigger issue with the refrigerator's sealed system.
You get a price before any work starts. If the fix genuinely isn't worth it — an aging unit needing a sealed-system repair, say — a straight answer beats a doomed repair.
Terre Haute's water comes from three vertical wells plus a horizontal radial collector well next to the Wabash River, disinfected with chloramine — details in the utility's own Consumer Confidence Report, the source of the 330 ppm hardness average. For an ice maker, that mineral load is what's most likely to scale a fill valve or narrow a line over time — not a defect in the appliance.
Not every provider describes the water the same way, either: Sears Home Services' own Terre Haute page calls it merely "moderately hard" — short of the utility's 330 ppm figure. See their page. Either way, a scaled valve or line is worth ruling out before assuming the whole unit needs replacing.
Timing matters too. Indiana State University's fall 2026 move-in runs from Bridge Week on August 9 through general move-in August 14–15 and returning students August 16 — a stretch that turns over many off-campus rentals near campus. See ISU's housing move calendar. If you've just moved into a place this month and the ice maker has never worked well, that's often a pre-existing hard-water or maintenance issue from before you arrived, not anything you did.
If a technician finds the ice maker trouble is really a dying refrigerator, see the refrigerator repair page for what that visit looks like and what local disposal actually requires.
Whether water is reaching the unit at all. A technician traces the supply line back to the shutoff valve before testing the inlet valve, module, or switches — it's the quickest way to tell a simple blockage from a failed part.
The utility's own Consumer Confidence Report puts local water hardness at an average of 330 ppm, ranging 280–400 ppm — well into "very hard" territory. That mineral load is a documented factor in scaled valves and lines. Source.
Usually mineral buildup in the fill tube or valve restricting water flow, or a filter that's overdue for replacement. Either can be checked and, if needed, addressed in a single visit.
Often, yes — a frozen or restricted line is a separate issue from the ice maker unit itself, and a technician can usually tell the two apart quickly once the panel is off.
It can slow future mineral buildup, though it won't undo scale that's already formed. Whether it's worth installing one is a fair question to ask while a technician is already looking at the line.
It depends on the fridge's age and what else it's showing signs of. A technician who's already testing components is well placed to give you a straight answer on both — see the repair-or-replace guide for how to think it through.

Not necessarily. It's common enough in Terre Haute rentals, especially around ISU's mid-August move-in weeks, for an ice maker to have an unresolved hard-water or maintenance issue that predates the current tenant.
