Of everything in a Johns Island kitchen, the ice maker suffers most from well water. Its fill valve is a small solenoid with a fine screen, and scale closes it a little every cycle until the cubes come out hollow, then small, then not at all. We repair the ice maker inside your refrigerator, fifteen minutes down Maybank Hwy: valve tested, freezer temperature checked, fill measured, one price in writing.
Same $99 diagnostic, same written quote, same written warranty on every machine we fix in Johns Island.
An ice maker is the last thing in the house to get water and the first to show what is in it. On a well-water house off River Rd, Bohicket Rd, Plow Ground or Main Rd, the fill valve behind the refrigerator sees hard water at full pressure every harvest. Scale builds on the screen and inside the valve body. The fill gets shorter, so the cubes go hollow. Then the valve sticks and either the fill tube freezes solid or the bin floods. The filter clogs months before its light says so. None of this is the module failing; it is the water side, and that is where a Johns Island ice maker repair usually starts.

The Maybank Hwy subdivisions and the neighborhoods out toward Freshfields are on treated water and their ice makers fail more conventionally: a module motor that quits, a mold heater that opens, a bin sensor that thinks the bin is full, a door harness on a French-door unit that has flexed one time too many. Then there is the garage. A second refrigerator in a Johns Island garage sits in ninety-degree air from June to September, its freezer creeps up toward fifteen degrees, and the ice maker inside it stops cycling. Bring it back to temperature and the ice comes back. We check that before anything gets replaced.
The classic well-water progression: a scaled fill valve delivering less water each cycle. We measure the fill per harvest, meter the valve coil, inspect the screen and check the filter date. A valve that has scaled internally is replaced; a clogged filter is swapped; and we tell you which one it was.
Freezer temperature first, then water supply, then the valve, then the module motor. On a garage refrigerator the temperature alone is often the answer. On a kitchen unit off Bohicket Rd it is more likely the valve. Each step has a test, and the meter and thermometer settle it before a part is named.
A valve that dribbles after it should have closed, a failed fill tube heater, or a freezer running colder than the door line tolerates. Scale is the usual reason a valve dribbles on Johns Island. We thaw it properly, then fix the cause so it does not refreeze in a month.
A fill valve that no longer seats, a cracked fill cup, a misaligned tube, or the refrigerator's defrost drain overflowing into the freezer floor. We watch a fill cycle with the panel off and follow the water to its source. On a raised house near the Kiawah River, that water heads for the crawlspace.
A filter long overdue, which well water clogs fast, an old bin absorbing freezer odors, or a supply line gone soft. On some wells the taste is simply the water, and a better filter is the answer. We check the filter date, the line and the ice itself and tell you plainly.
A bin sensor or paddle reading full, an intermittent module motor, or a door switch telling the ice maker the door is open. On French-door units in the new Maybank Hwy houses, the harness through the door hinge is the common culprit. We meter the sensor and switch and run several harvests to catch it.
The technician asks whether the house is on a well, checks the freezer temperature, then triggers a harvest and catches the fill in a measuring cup. Short fill on a well-water house points at the valve or filter; normal fill with no ice points at the module or temperature. The meter confirms it: coil resistance on the valve, continuity on the mold heater, motor operation on the module. Fifteen minutes and the cause is measured, not guessed. That is the $99 diagnostic. One written price follows. Approve it and the $99 is inside that price. Decline and $99 is the whole bill.
We repair the ice makers built into Whirlpool, GE, Samsung, LG, Frigidaire, KitchenAid, Bosch, Maytag and Kenmore refrigerators across Johns Island, plus the modules inside Sub-Zero, Thermador, Viking and JennAir built-ins in the newer kitchens along the Kiawah River and near Freshfields. We do not service standalone or under-counter ice machines. Rental homes on the Seabrook side get turnover-day scheduling because an empty ice bin is the first thing a guest notices. The van carries fill valves, ice maker modules, fill tubes and heaters for the common models, so most repairs finish the same visit. Book online and up to $20 comes off the repair, never the diagnostic. Written warranty on every job.
