Why Is Your Whirlpool Ice Maker Not Dumping Ice?

whirlpool ice maker troubleshooting

If your Whirlpool ice maker is not dispensing ice, there could be several reasons. Potential issues include a restricted water supply, a malfunctioning water inlet valve, or problems with the freezer's temperature. Other common problems might be a clogged dispenser chute or a misaligned control arm.

To find the exact problem, you should check the ice maker thoroughly, from ensuring the power switch is on to examining the ice maker's components. Once you identify the issue, you can fix it to get the ice maker working again.

Checking the Power Switch

To check the ice maker's power switch in a Whirlpool Refrigerator, a technician performs a continuity test. If the switch fails the test, replacement is necessary for the ice maker to work.

If the switch passes, the technician then checks if the ice maker is getting the right voltage by testing between points L and N on the power module. Incorrect voltage requires fixing the electrical supply.

Next, the technician forces the ice maker into a harvest cycle by shorting points T and H. They must watch for the ejector rake to move, confirming that the switch is working. The shorting wire should be removed quickly to prevent damage.

Additionally, the technician checks that the freezer is set to the right temperature and that the door switch is working, as it can stop the ice maker when the door is open. If the ice maker makes ice but doesn't release it, the problem might not be the power switch, but could be due to temperature settings or a mechanical issue.

Inspecting the Water Supply

Inspect the refrigerator's water supply line for any bends or blockages to ensure the ice maker receives a consistent water flow. Straighten any kinks to improve water flow.

Check the water inlet valve that supplies water to the ice maker. If the valve is damaged or not working properly, replace it to allow a steady water supply.

Ensure the freezer's temperature setting is correct to prevent the water line from freezing, which would stop ice production.

Regularly check and replace the water filter as recommended by the manufacturer to prevent clogs that could disrupt water flow.

Lastly, confirm that the fill valve is working and that water pressure is adequate, as low pressure can result in small or irregular ice cubes and affect ice dumping. Proper maintenance of these components is essential for consistent ice production and to prevent issues with the ice dispensing mechanism.

Assessing Freezer Temperature

Checking the freezer temperature is an important step when troubleshooting a Whirlpool ice maker that isn't dispensing ice. The freezer should be set between 0-5 degrees Fahrenheit for optimal ice production. If the ice maker isn't working, it could be because the temperature is outside this range. Use an accurate thermometer to verify the freezer's temperature matches the thermostat's display.

If the temperature is incorrect, adjust the thermostat and continue to monitor. A steady temperature in the recommended range is necessary for ice to form properly. The ice mold thermostat initiates the harvest cycle when the correct temperature is reached, allowing the ejector arms to release the ice. If the freezer isn't cold enough, the ice won't be solid enough to be ejected.

A faulty mold thermostat can also cause issues. If the ice maker freezes ice but doesn't release it, test the thermostat with a multimeter for continuity. A defective thermostat may not trigger the harvest cycle correctly, causing ice to remain in the mold.

Evaluating the Ice Maker Mechanism

The ice maker in a Whirlpool refrigerator consists of several components that need careful inspection if the unit stops producing ice. To troubleshoot, diagnose each part starting with the ice maker thermostat. Use a multimeter to check the thermostat for continuity. A faulty thermostat can prevent ice production.

Ensure the dispenser paddle or pad is pressed down properly, as it affects the ice level in the bin. If no ice is being dispensed, check for and remove any blockages in the chute. Empty and clean the ice bin as part of the maintenance.

For electrical issues, measure the voltage between holes L and N on the ice maker's power module. A correct voltage reading allows for a manual harvest cycle test by shorting holes T and H, which checks if the ice maker can complete a cycle.

If these actions don't fix the issue, consider replacing the ice maker. However, consult customer service before doing so to see if the problem can be resolved with additional adjustments or if a replacement is necessary.

Troubleshooting the Control Arm

A misaligned or faulty control arm often leads to issues with a Whirlpool ice maker not ejecting ice. The control arm is a key part of the ice-making system, detecting the amount of ice in the bin and controlling ice production. An incorrectly positioned arm can cause the ice maker to stop making ice, mistaking the bin for being full.

To troubleshoot, ensure the control arm is unobstructed and moves freely. If the arm is stuck or broken, it may need to be adjusted or replaced.

For ice makers that aren't working, refer to the user manual for instructions on correctly positioning the control arm. Sometimes, the arm can be manually moved to restart the ice-making process. If adjusting the arm doesn't fix the issue, further examination is necessary.

Troubleshooting might also require checking the electrical continuity of the ice maker's components. Before doing this, disconnect the refrigerator's power supply. Use a multimeter to test voltage between holes L and N on the ice maker's power module. To initiate the harvest cycle, you can bridge holes T and H. This helps determine if the control arm is operational or if other parts need replacing, such as the mold thermostat, switch, ice level control board, door switch, or ice maker module.

Unclogging the Dispenser Chute

A clogged dispenser chute can prevent a Whirlpool ice maker from dispensing ice, requiring inspection and cleaning. Ice clumps can block the chute, stopping new cubes from falling through. To ensure the ice maker works properly, the chute must be kept clear.

To unclog the chute, first remove the ice storage bin for full access. Check the chute for ice chunks and use a plastic utensil to gently remove any obstructions, avoiding sharp tools that can damage the ice maker. Once cleared, replace the ice bin correctly to ensure it's aligned for the ice maker to function.

Check the dispenser paddle or pad to make sure it's working, as it controls ice release when pressed by a glass.

Regular cleaning of the ice chute and storage bin bottom is necessary to prevent clogs. After cleaning, dry the area to stop ice from sticking and forming new blockages.
