Understanding the Problem
What this part is and what it does: The WPW10300022 is a complete refrigerator ice maker assembly used in many Whirlpool, KitchenAid and Maytag models (sometimes called the Barracuda ice maker). It contains the motor/gearing, fill cup, ejector/harvest mechanism and the thermostat/harvest heater circuitry that cycles, fills and ejects ice cubes. Step-by-step diagnostic and repair instructions: 1. Verify symptoms and basic checks: a. Remove the ice bin and check for jammed cubes or ice buildup around the ejector. Clear any obstruction. b. Confirm freezer temperature is in the proper range (0°F to 5°F / -18°C to -15°C). Too warm and the maker won’t cycle. c. Make sure the water supply to the fridge is turned on and the water line is not kinked. Check household water pressure. 2. Check for ice formation and fill issues: a. If there are no cubes or only a few, check the fill tube for an ice clog (small plastic tube that delivers water to the fill cup). Thaw with warm (not boiling) water if iced. b. Inspect for continuous water flooding — that usually points to a water inlet valve or a stuck fill cup. 3. Test the ice maker itself: a. Locate the ice maker assembly and find the test/diagnostic button or the two ice maker terminals. Many Whirlpool-style makers have a small push button or two spade terminals labeled for a jumper. b. With the fridge plugged in, press the test button or momentarily jumper the two terminals (use a plastic or insulated jumper) to force a harvest cycle. Watch for the motor to turn and the heater (if present) to run briefly. If the motor doesn’t run but the unit has power, the ice maker is likely bad. c. Use a multimeter to check continuity of the motor and heater circuits if you’re comfortable doing so (unplug fridge before probing). If there's no continuity where expected, ice maker replacement is indicated. 4. Check the water inlet valve (if the maker cycles but no water fills): a. The valve is mounted at the refrigerator rear at the water line entry. If the ice maker runs a fill cycle but no water enters the fill cup, the valve or its solenoids may be bad or the water pressure may be too low. b. Test for 120VAC (or manufacturer-specified voltage) at the valve during a fill cycle: if voltage is present and the valve doesn’t open, replace the valve. 5. When to replace the WPW10300022 ice maker assembly: a. Ice maker does not start or motor does not run during a forced cycle (and wiring/power to the unit is correct). b. Ejector gears are stripped, thermostat/harvest heater fails, or the unit floods and overfills despite proper water valve function. c. Visible physical damage or severe corrosion of assembly components. 6. Basic replacement steps (general procedure): Tools needed: Philips screwdriver, nut driver or socket set (commonly 1/4" or 5/16"), needle-nose pliers, towel, and optionally a multimeter. a. Safety first — disconnect the refrigerator from power and shut off the water supply to the fridge. b. Remove the ice bin and any shelving blocking access to the ice maker. c. Locate and remove the mounting screws/clips that secure the ice maker to the freezer liner or bracket. Support the unit as you remove the last fastener. d. Carefully pull the ice maker slightly forward to access the wiring harness and (if equipped) the quick-disconnect water fill tube connection. Unplug the wiring harness and remove any retaining clips for the water tube. Note orientation for reassembly. e. Remove the old ice maker fully and set aside. Install the new WPW10300022 by reversing removal steps: connect wiring harness, reattach fill tube/clip, mount and screw the unit into place. f. Restore power and water. Run a forced test cycle (press test button or jumper terminals) to confirm the new unit motor runs and that the fill cup receives water. g. Replace ice bin and monitor the first couple of cycles for proper fill level and harvest/eject. Expect a few hours for the first batch to freeze fully. Safety note: Always disconnect power before unplugging or handling wiring and be cautious when testing live voltages. If you are not comfortable with electrical testing or handling refrigerant components, contact a professional technician.
Common Symptoms
No ice production, ice maker won’t cycle, cubes not ejected, overflowing/continuous filling, or visible damage/corrosion to the ice maker assembly.
Common Causes
- Faulty ice maker motor or control/thermostat inside the ice maker assembly
- Blocked/iced fill tube or low water pressure preventing proper fill
- Defective water inlet valve (valve doesn’t open during fill)

Helpful Repair Tip
Force a harvest cycle: press the ice maker’s test button or momentarily jumper the two ice maker terminals with the fridge powered. If the motor or heater doesn't run while power is present, the WPW10300022 assembly is usually the failed component.
Frequently Asked Questions
Can I replace the WPW10300022 ice maker myself?
Yes — many owners can replace this ice maker with basic hand tools. Turn off power and water, remove the ice bin, unmount the old assembly, disconnect the plug and fill tube, install the new unit and reconnect. If you’re not comfortable testing electrical components or working behind the fridge, hire a technician.
Will replacing the ice maker fix all no-ice problems?
Not always. If the ice maker cycles but no water is delivered during the fill, the water inlet valve, water line, or low household water pressure may be the cause. Confirm the maker actually runs during a forced cycle; if it runs but doesn’t fill, inspect/replace the valve or clear a clogged fill tube.
