Understanding the Problem
The ice maker in the Whirlpool ED5KVEXVB03 is the component that fills with water, freezes it to form cubes, and then ejects the cubes into the bin. Typical problems are: no ice production, partial fill (small or hollow cubes), not harvesting (not ejecting), leaking or continuous running water, and noisy operation. Below are step-by-step diagnostic steps and practical repair instructions you can follow. 1) Confirm the symptom and gather basic info: remove the ice bin and inspect for ice jams, frost buildup, or standing water. Note whether the ice maker runs but doesn’t dispense, never cycles, or leaks. 2) Safety and preparation: unplug the refrigerator or switch off its breaker and shut off the water supply to the fridge before working. Have a multimeter, small nut drivers (5/16" and 1/4"), needle-nose pliers, and towels handy. 3) Check the water supply and filter: a blocked/old filter or kinked supply line often causes small or hollow cubes or no fill. Replace the filter (or remove temporarily) and ensure the water line has full pressure by briefly opening the inlet valve at the wall. 4) Inspect the water inlet valve: the valve controls fill. With power on and water valve on (only if you know how to safely test live circuits), manually trigger an ice fill cycle (see step 7) and listen for the valve. If the valve doesn’t click or won’t let water through, it’s a common failure. 5) Check the ice maker thermostat/thermostat sensor (if equipped): some Whirlpool ice makers use a temperature-controlled switch that tells the motor to drive the harvest cycle when the mould is frozen. If the sensor thinks the mould is warm it won’t harvest. Excessive frost on the family evaporator or a failed defrost system can cause the mould to not reach the proper temperature. 6) Test the ice maker motor/assembly: restore power and, using the ice maker’s test/diagnostic pin or by lifting/tripping the fill arm (if present), force a harvest cycle. If the motor doesn’t run but there is 120VAC at the harness connector, the ice maker motor or control module is bad and the ice maker assembly usually needs replacement. 7) Force a diagnostic or test cycle: on many Whirlpool units you can start a harvest by pressing the test/diagnostic button (consult owner manual or service sticker) or by manually tripping the feeler arm and using a jumper on the test pins. Follow model-specific instructions — if unsure, consult service manual. 8) Examine the ejector and mold for physical damage: broken gears, snapped ejector claws, or ice bridges can prevent harvesting. Clear jams and rotate the motor manually (power off) to check gear engagement. 9) Inspect the ice maker wiring harness and connections: corrosion or a loose connector can interrupt the motor, fill valve, or sensor signals. Clean and reseat connectors. 10) Replace the water inlet valve or the ice maker assembly as needed: if the valve fails to open under test, replace it (replacement is usually at the back or underside and involves turning water off, disconnecting the line, removing two screws, unplugging the harness). If the ice maker motor/control is dead (no motor movement during a forced harvest with power present), replace the entire ice maker module. 11) After repair, restore water and power, run several test cycles, check for proper fill height (about 3/8" to 1/2" of mold depth), and inspect for leaks. 12) Final steps: let the unit make several cycles (may take 24–48 hours to fill the bin). Dispose of the first few cycles of ice after a water-line repair. Safety note: If you are not comfortable testing live voltages, replacing sealed valves, or working with water connections, call a qualified appliance technician. Always disconnect power and shut off the water before removing parts.
Common Symptoms
No ice production; small or hollow cubes; ice maker fills continuously; ice maker won’t eject/harvest; water leaking into bin or onto floor; loud clicking or grinding noises during cycle.
Common Causes
- Clogged/old water filter or low water pressure to the inlet valve
- Failed water inlet valve (won’t open or only partially opens)
- Bad ice maker assembly (motor/switch/control) or broken ejector gears
- Frozen/frosted evaporator or failed defrost system preventing proper freeze/harvest
- Blocked or kinked water line, bad harness/connector, or incorrect installation

Helpful Repair Tip
To confirm a faulty ice maker motor/module: restore power, manually force a harvest cycle (test button or trip arm). If you measure ~120VAC at the ice maker harness during a commanded harvest but the motor doesn't move, the ice maker assembly is bad and should be replaced.
Frequently Asked Questions
How do I tell if the ice maker itself is bad or the water inlet valve is the problem?
Start by checking whether the ice maker is getting a fill. Remove the bin, force a harvest cycle, and observe: if the ice maker runs and ejects but no water fills the mold, the inlet valve or water supply is the likely culprit. If the inlet valve clicks and supplies water but the ice maker doesn’t cycle or the ejector doesn’t turn when commanded and there is voltage present at the ice maker harness during a harvest, the ice maker assembly is bad. Also check the water filter and water pressure before replacing parts.
Can I replace the ice maker myself on a Whirlpool ED5KVEXVB03?
Yes — many homeowners can replace the ice maker assembly themselves with basic tools. Key steps: shut off power and water, remove the ice bin and interior cover, unplug the ice maker harness and water line (if applicable), remove mounting screws, swap in the new assembly, reconnect wiring and water, turn water and power back on, and test several cycles. However, if you’re uncomfortable with electrical testing, water line disconnection, or diagnosing defrost issues, hire a qualified technician.
