Understanding the Problem
If your Whirlpool WRB322DMBM01 ice maker has stopped producing ice, is slow to produce, makes small cubes, or fails to harvest, the issue can come from several common components or from serviceable conditions (temperature, water supply, or a clogged filter). The ice maker system requires a reliable water supply, a correctly working inlet valve, proper freezer temperature, and a functioning ice maker module/thermostat to sense and eject ice. Diagnosis starts with simple checks: confirm the water supply line is on, verify the water filter is not clogged, and check the freezer temperature (ideal ~0°F / -18°C). If those are OK, the problem most often traces to a faulty ice maker assembly (module or motor), a defective water inlet valve, a frozen or blocked fill tube, or a failed temperature-sensing thermostat/thermistor. Addressing the correct part will restore normal ice production and harvesting.
Common Symptoms
No ice production, slow ice production, small or misshapen cubes, ice stuck in mold/not ejecting, continuous water leaking into the ice bucket, or ice maker not cycling.
Common Causes
- Clogged or old water filter / restricted water supply
- Faulty water inlet valve or inadequate water pressure
- Defective ice maker assembly (motor/module/thermostat) or harvest mechanism
- Frozen or blocked fill tube or poor freezer temperature
- Ice level sensor/arm or door switch malfunction

Helpful Repair Tip
Run the ice maker’s built-in diagnostic (or press the test switch) to watch the fill/harvest cycle; if the motor doesn’t run, suspect the ice maker/module. If the motor runs but no water fills the mold, check the water inlet valve and filter or a frozen fill tube.
Frequently Asked Questions
How do I test the ice maker on a WRB322DMBM01?
Locate the ice maker test switch or run the refrigerator's diagnostic mode. With the ice bin removed, press and hold the test switch for several seconds; you should hear the ice maker motor run through a harvest cycle. If the motor runs but no water fills the mold, check the water inlet valve and filter. If the motor does not run, suspect the ice maker assembly or its control/module.
Can I replace the ice maker or inlet valve myself?
Yes — many DIYers can replace the ice maker or inlet valve. Safety steps: unplug the refrigerator and shut off the water supply. Remove the ice bin and disconnect the ice maker wiring harness, then unfasten the mounting screws to remove the unit. For the inlet valve, access behind the refrigerator, disconnect water line and power, remove the mounting screws, and swap the valve. Always verify replacement part compatibility with your exact model/serial and test the system after reassembly.
