Understanding the Problem
Owners of the WRB322DMBM01 may find the ice maker has stopped producing ice, makes small or hollow cubes, overflows, or runs continuously. Many issues that look like a failed ice maker are actually caused by a lack of water supply, a clogged or frozen fill tube, or a failed water inlet valve. Electrical faults in the ice maker module, a frozen mold, or mechanical jams in the ejector assembly are other common reasons the unit doesn’t harvest or dispense ice correctly. This guide walks through the most common faults, how to confirm which component is bad, and the parts typically replaced to restore operation. Start with simple checks (power, water supply, and filter status) before assuming the ice maker assembly itself is defective—those easier checks will save time and money and point you to the correct part to replace.
Common Symptoms
No ice production, slow or no fill, small or hollow cubes, continuous motor noise or clicking, water leaking into the ice bin, or ice stuck in the mold that doesn't eject.
Common Causes
- Failed ice maker module (motor/gear assembly or control/thermostat) preventing harvest or fill
- Faulty or blocked water inlet valve / low water pressure to the ice maker
- Frozen or blocked water fill tube, clogged filter, or frozen dispenser/fill path

Helpful Repair Tip
First confirm the ice maker is getting water and power: listen for a short fill (valve hum) during a fill cycle, manually advance the ice maker into a harvest cycle (using the advance lever or motor) to check ejection/heater function, and inspect the fill tube for ice blockage. These quick tests tell you whether the problem is the inlet/fill or the ice maker module itself.
Frequently Asked Questions
My ice maker stopped making ice completely — do I need to replace the whole ice maker?
Not always. Begin with these checks: ensure the refrigerator and ice maker are powered on, confirm the water supply and filter are not clogged, and manually advance the ice maker through a cycle to see if the motor attempts to run and if the mold heats during harvest. If you hear the fill valve operate but the mold stays full, the ice maker module (motor or harvest thermostat) is likely bad. If there's no fill, the inlet valve or water supply is the common culprit. Replace only the failed component after confirming with these tests.
Why are my ice cubes small or soft?
Small or soft cubes are usually caused by low water pressure (partially closed supply valve, clogged filter, or kinked line), a partially clogged inlet valve, or frequent short cycles preventing the ice from fully freezing. Check the water pressure, replace the water filter if it's due, and verify the freezer temperature is set cold enough (around 0°F / -18°C).
