Quick Answer: The five parts most likely to fail on a countertop or nugget ice maker are the water pump (grinding noise, no freezing), the control board (unresponsive display, no cycle start), the auger motor (jammed or grinding on nugget machines), the door gasket (leaking or frost buildup), and the water filter (covered separately in our filter guide). Pumps and gaskets are cheap and largely universal — expect $18-$55 for a pump, per current Amazon and appliance-parts listings — while control boards and auger assemblies are pricier and brand-specific. Fixr.com’s repair-cost data puts a professional repair visit at $100-$225 once labor is added, which is often more than a budget machine costs new, so the table below helps you decide whether to order the part or replace the unit.
Before ordering anything, match the symptom to the part — ordering the wrong component because “it’s not making ice” is the single most common wasted purchase in ice maker repair, since three or four different failures all produce that exact same complaint.
Match your symptom to the part
| Symptom | Likely part | Typical part cost | Universal or brand-specific |
|---|---|---|---|
| Grinding/whining noise, water fills but won't freeze | Water/circulation pump | $18-$55 | Mostly universal |
| Dead display, won't start a cycle, buttons unresponsive | Control board (PCB) | $35-$90 | Brand/model-specific |
| Auger jammed or grinding (nugget/pebble machines) | Auger motor assembly | $40-$100 | Brand/model-specific |
| Water leaking around the door, frost buildup | Door gasket/seal | $10-$20 | Model-specific |
| Flat/off taste, slow fill on plumbed units | Water filter | $10-$35 | Format-specific — see our filter guide |
| Lost or cracked scoop | Ice scoop | $5-$12 | Universal |
If your symptom is “no ice at all” and you haven’t already worked through basic troubleshooting, start with our ice maker not making ice guide first — it rules out simple fixes (low water, a stuck float switch, a full bin sensor) that don’t require buying any part at all.
Water pump: the most common failure
The water/circulation pump runs on almost every cycle, which makes it the part most likely to wear out first on a machine that sees daily use. A failing pump usually announces itself with a grinding, whining, or straining sound paired with water that fills the reservoir but never actually freezes into ice — the pump can’t circulate water fast enough over the freezing element for ice to form. Most replacement pumps for countertop and nugget machines are largely interchangeable across brands, since a handful of OEM suppliers make the vast majority of them, and current listings run $18-$55 for the part.

Control board: pricier, and worth confirming first
The control board is the machine’s brain — it reads the sensors, times the cycle, and drives the pump, compressor, and auger motor. A dead display, a unit that won’t start a cycle at all, or buttons that don’t respond usually points here. Boards run $35-$90, noticeably more than a pump or gasket, and unlike pumps they’re built to each manufacturer’s exact wiring harness and housing, so you need your specific model number rather than a universal part. Before ordering one, it’s worth ruling out a simple reset (unplug for 60 seconds) and a stuck float or bin sensor, both of which can mimic a dead board without actually being one — our ice maker not making ice guide walks through those cheaper checks first.
Auger motor: nugget and pebble-machine specific
Nugget and pebble-ice machines use an auger to compress and extrude ice, and that motor assembly is the part most exposed to mechanical stress from ice jams. A grinding or screeching noise (covered in more depth in our ice maker making noise guide) that persists after clearing a visible jam usually means the auger motor or its bearing has actually worn out rather than just being blocked. These run $40-$100 and, like control boards, are model-specific rather than universal.

Door gasket and water filter
A door gasket that’s cracked, compressed, or no longer seating fully lets warm air in and can show up as frost buildup or water leaking around the door edge — our ice maker leaking guide covers diagnosing that versus other leak causes. Gaskets are inexpensive ($10-$20) but are cut to each model’s exact door shape, so order by model number. The water filter is a separate, more frequent replacement covered in full in our ice maker filter replacement guide — GE’s own spec for the Opal’s cartridge rates it for about 3 months or 150 gallons, whichever comes first.
Repair vs. replace: when a part swap isn’t worth it
Fixr.com’s cost data puts a professional ice maker repair visit at $100-$225 once labor is factored in, and most budget-to-mid-range countertop ice makers on this site sell new for $150-$300. Run the math before ordering: a $20-$55 pump or a $10-$20 gasket you install yourself is almost always worth it. A control board or auger motor near $90-$100 is still usually worth it on a machine under 2-3 years old. But if a technician is quoting you for a failed compressor, or the machine is already past its GE 1-year warranty and showing multiple issues at once, replacing it outright is often the cheaper and less frustrating path — see our best countertop ice maker and best nugget ice maker guides for current picks.
The bottom line
Match the symptom to the part before you buy anything — a pump, board, auger motor, gasket, filter, and scoop can all produce a “not making ice” complaint, but only one of them is actually broken. Pumps and gaskets are cheap, mostly universal, and worth replacing on almost any machine; control boards and auger motors cost more and need your exact model number; and once a repair quote starts approaching the price of a new budget unit, replacing the machine usually wins.
