KitchenAid Refrigerator Ice Maker Not Working
KitchenAid refrigerator ice makers share common failure points across all model families — and most problems are solved without replacing the ice maker module. Check the simple causes first: ice maker arm position, freezer temperature, water supply valve, and water filter. The water inlet valve (WPW10498990) and a frozen fill tube account for the majority of cases where everything else checks out. Models covered: KRFC704FPS (French door), KRMF706ESS (4-door), KRFF507ESS (French door), KRSF505ESS (side-by-side).

Common Symptoms
- No ice production at all
- Ice cubes are small, hollow, or misshapen
- Ice maker arm stuck in up (off) position
- Ice maker makes noise but produces no ice
- Ice clumping together in the storage bin
Most Likely Causes
- 1
Ice Maker Turned Off or Arm in OFF Position
The most common cause of sudden ice maker failure is accidental shutoff. On KitchenAid models, this may be a power switch (KRFC704, KRMF706) or a bail wire arm (KRFF507, KRSF505). If the arm is in the up position, the ice maker is off. This is always the first thing to check.
- 2
Freezer Temperature Too Warm
KitchenAid ice makers require a freezer temperature at or below 0°F to complete a full freeze cycle. Above 10°F, ice production slows significantly or stops entirely. A common cause of gradual ice production decline is a temperature creep caused by dirty condenser coils or a failing evaporator fan.
- 3
Clogged Water Filter
KitchenAid recommends replacing the water filter every 6 months. A clogged filter reduces water pressure below the 20 psi minimum required for the ice maker to fill properly. The filter indicator light will illuminate when replacement is due — part numbers WF-NL240 or WF-NL300 depending on model.
- 4
Failed Water Inlet Valve
The water inlet valve (WPW10498990) is a solenoid valve that opens to supply water to the ice maker and dispenser. Sediment can clog the valve screens or the solenoid coil can fail electrically. A properly functioning ice maker that gets no water is a strong indicator of valve failure. The solenoid should test 200–500Ω — OL indicates a failed winding.
- 5
Frozen Ice Maker Fill Tube
The small plastic tube that carries water from the inlet valve to the ice maker mold can freeze solid. This is especially common if the freezer temperature drops below 0°F or if the fill tube heater (WPW10229647) has failed. When the fill tube is frozen, the inlet valve opens but no water reaches the mold.
- 6
Failed Ice Maker Module
The ice maker module (WPW10757851 for KRFC704/KRMF706, other part numbers for KRFF507/KRSF505) contains the thermostat, drive motor, and ejector mechanism. If the arm cycles but water does enter the mold yet ice still doesn't eject, or if the arm doesn't cycle at all, the module may have failed. Replace as a complete assembly.

Quick DIY Checks
Turn off the ice maker before working on the water inlet valve — a running ice maker cycle will call for water mid-repair. Turn off the water supply line before disconnecting any water connections.
- 1Confirm the ice maker is turned on: locate the power switch or bail wire arm on the ice maker. On KRFC704 and KRMF706 models, look for a switch on the side of the ice maker unit. On KRFF507 and KRSF505, look for a wire bail arm — it must be in the down position for ice production. Lower the arm manually if it's stuck up due to ice buildup.
- 2Check freezer temperature: place a thermometer in the freezer and verify it reads 0°F or below. Allow 24 hours after any adjustment. If the freezer is above 10°F, fix the cooling problem first (dirty condenser coils, evaporator fan, defrost system) before diagnosing the ice maker further.
- 3Inspect the water supply line and shut-off valve: pull the refrigerator away from the wall. Locate the shut-off valve (usually behind the fridge or under the sink). Verify it is fully open. Inspect the water supply line for kinks, especially at the point where it connects to the back of the refrigerator. A kinked or closed line = no ice and no water dispenser.

Repair vs Replace
Ice maker repairs are cost-effective on KitchenAid refrigerators at any age. A water filter costs $15–$40. A water inlet valve is $30–$60. A complete ice maker module assembly is $60–$120. These are all straightforward DIY repairs. KitchenAid refrigerators are built to last 15+ years — repair is almost always the right call unless the sealed system has also failed.

Frequently Asked Questions
- Why did my KitchenAid ice maker suddenly stop working?
- The most common causes of sudden ice maker stoppage are: the bail arm accidentally flipped to the off position, the freezer temperature drifted above 10°F, or the water supply was interrupted (kinked line, closed valve, or clogged filter). Check these three things before assuming a part has failed — most sudden stoppage calls are resolved without any parts replacement.
- How do I reset a KitchenAid refrigerator ice maker?
- On most KitchenAid ice makers, press and hold the test/reset button on the module face for 3 seconds. The ice maker will cycle through a complete sequence — you'll hear the motor turn, the ejector arms rotate, and water fill the mold. Allow 24 hours for a full bin after a reset. If the ice maker does not respond to the reset button, the module may have failed.
- My KitchenAid ice maker makes noise but no ice drops — what's wrong?
- If the ice maker cycles (you hear the motor and ejector arms move) but no ice drops, the molds are not filling with water. Check the water supply line, shut-off valve, and water filter first. Then test the water inlet valve WPW10498990 with a multimeter — a failed solenoid (OL reading) means water cannot reach the molds even though the module is cycling normally.
- How long does it take a KitchenAid ice maker to start producing ice after a fix?
- After resolving a water supply or mechanical issue, allow up to 24 hours before expecting a full ice bin. The ice maker needs time to complete several freeze cycles to fill the bin. If no ice has appeared after 24 hours, verify the freezer is at 0°F and run a test cycle by pressing the test button on the module.
