KitchenAid KUIC18NNXS0 ice cube maker Parts

For the KitchenAid KUIC18NNXS0 freestanding ice maker, we reset operation by turning the unit OFF and back ON at the control panel; if the Service light comes back on, cycle OFF then ON again. A full power reset is unplugging the ice maker briefly, then restoring power (see the KUIC18NNXS0 owner's manual).

Reset steps for KUIC18NNXS0

• Press OFF to stop ice maker operation.
• Wait about 10 seconds.
• Press ON to restart ice production.
• If the Service light is on, turn the ice maker OFF, then ON again.
• If you want a full reset, unplug the ice maker (or disconnect power), wait 1 minute, then plug it back in.

Quick checks that prevent “false” reset problems

A reset will not help if the ice maker cannot fill, freeze, or harvest normally. Check these basics first:

• Confirm the unit is set to ON (On/Off does not remove power).
• Make sure the ice maker is level front-to-back and side-to-side.
• Verify the water supply is on and the water line is not kinked.
• Clean lint and dust from the condenser area (airflow problems reduce ice production).
• Allow time after a reset; first ice can take up to 24 hours.

What the lights and buttons mean

Control/indicator	What it does	What to do after a reset
On/Off	Starts or stops ice production (does not cut power)	Leave ON for normal operation
Service light	Indicates service is needed	Cycle OFF then ON
Clean/Reset status light	Signals when cleaning is due	Clean when it turns red or output drops
Holiday mode	Disables ice production and turns off interior lights	Turn off Holiday mode to make ice

Why it matters

Resetting clears a stalled operating state, but steady ice production depends on correct setup (leveling), good airflow at the condenser, and consistent water supply. Those items directly affect freeze time, harvest, and daily ice capacity.

If your KitchenAid KUIC18NNXS0 freestanding ice maker runs but makes no ice, the cause is usually a control setting, water supply issue, drain problem, or a condition that stops the freeze and harvest cycle (leveling, scale buildup, or a full-bin sensor). Use the checks below to pinpoint it quickly; see the KUIC18NNXS0 owner's manual for model-specific steps.

Quick checks that fix most “no ice” problems

• Confirm the control is set to ON.
• Verify the water supply line is connected and the shutoff valve is fully open.
• Make sure the unit has power (plugged in; breaker not tripped).
• Check room temperature; it must be above 55°F (13°C) or the bin thermostat can shut the unit off.
• Inspect the drain cap; if it is loose, the water pan can empty and you can get thin ice or no ice.
• Look for kinks in the drain line or debris in the drain tube; clear any blockage.

What to check next (by symptom)

What you see	Most likely cause	What to do
Unit runs, no ice forms	Water not entering or draining incorrectly	Confirm supply is on; tighten drain cap; clear drain tube; remove drain line kinks
“Whooshing” sound, no ice	Water supply or drain pan connection issue	Confirm water supply is on; ensure drain cap is tight and drain pan pump is secure
Ice stuck between plate and grid	Unit not level or needs cleaning	Level the ice maker; run a cleaning cycle
Green light comes on with Clean button	Needs cleaning	Clean the ice maker system

Parts that commonly relate to “no ice” on this model

If the basic checks pass and you still get no ice, these KUIC18NNXS0 parts are commonly involved in water fill, sensing, or harvest:

• Freestanding ice maker water inlet valve W10585391 (controls water fill)
• Ice maker bin thermostat WPW10503764 (helps regulate shutoff based on bin conditions)
• Ice maker electronic control board WPW10226156 (controls cycle timing and operation)

Why it matters

This ice maker freezes water on an evaporator plate, releases the sheet to a cutter grid, then refills for the next cycle. If water cannot stay in the pan (drain cap loose), cannot enter (supply/valve issue), or the unit shuts off early (cold room or bin sensing), the cycle stops before cubes drop.

Yes. For the KitchenAid KUIC18NNXS0 freestanding ice maker, leaving it powered on for everyday use is normal as long as it has proper ventilation, correct room temperature, and a safe electrical connection. For longer periods away, we recommend shutting it down and draining it per the owner's manual.

What to check if you plan to run it continuously

• Keep the front completely unobstructed so airflow is not restricted.
• Maintain room temperature above 55°F (13°C) and below 100°F (38°C); best results are typically 70°F to 90°F (21°C to 32°C).
• Plug into a grounded 3-prong outlet; do not use an adapter or extension cord.
• Make sure the unit is level so it can operate properly.
• Confirm the cold water supply and drain setup are working correctly.

When we recommend turning it off

If you will not use the ice maker for several days (vacation, seasonal shutdown), shutting it down prevents stale ice, odors, and mineral buildup.

Typical shutdown steps include:

• Unplug the ice maker (or disconnect power).
• Remove all ice from the storage bin.
• Shut off the water supply.
• Drain the water pan (and protect the drain line if temperatures can drop below 32°F).

Quick guide: leave it on vs. shut it down

Situation	Best setting	Why it matters
Daily household use	Leave ON	Keeps ice production ready and consistent
Not using it for 3+ days	Shut down and drain	Prevents odors, scale, and stagnant water
Room below 55°F	Avoid running	The bin thermostat can shut the unit off unexpectedly
Front grille blocked	Avoid running	Poor ventilation reduces performance and can cause overheating

Why it matters

This model relies on steady airflow and the right ambient temperature to make ice efficiently. Running it in a too-cold room or with blocked ventilation often looks like an “ice maker not making ice” problem even when the controls are set correctly.

Parts that commonly relate to “stops making ice” symptoms

If the unit is powered on but ice production is inconsistent, these model-specific parts are often involved:

• Ice maker bin thermostat WPW10503764 (can shut the unit off based on sensed temperature)
• Freestanding ice maker water inlet valve W10585391 (controls water fill)
• Ice maker electronic control board WPW10226156 (manages operating cycles)
