Amana Refrigerator Ice Maker Not Working: Troubleshooting... | appliancefaults.com

Technical Background:

The refrigerator's Main Control Unit (MCU) manages the ice maker's operation, controlling the water inlet valve and the ice maker's harvest cycle. The MCU relies on sensors and timers to determine when to initiate ice production. Voltage is supplied to the ice maker module and the water inlet valve when the correct conditions are met.

Symptoms:

The Amana refrigerator dispenses water normally but the ice maker is not producing any ice.

Possible Causes:

Faulty ice maker module
Defective ice maker water inlet valve (partial blockage)
Frozen fill tube
Low freezer temperature setting
Issue with the door switch
Malfunctioning refrigerator MCU (Main Control Unit)

Solution:

1

Disconnect power to the refrigerator at the breaker panel (LOTO).
2

Check freezer temperature with a thermometer. It should be between 0-10°F.
3

Inspect the ice maker fill tube for ice blockage. Use a hair dryer on low heat to gently thaw if frozen.
4

Verify the ice maker is receiving power. Use a multimeter to test for 120V AC at the ice maker module.
5

Test the ice maker water inlet valve. Disconnect the water line and check for proper water flow when activated (energize with 120V AC briefly).
6

Examine the ice maker module for physical damage or wear. If damaged, replace the ice maker module.
7

Ensure the refrigerator door switch is functioning correctly. The ice maker should not cycle with the door open.

Safety Warning:

Disconnect power to the refrigerator before performing any repairs. High voltage is present in the control panel and ice maker area. Use proper lockout/tagout (LOTO) procedures to prevent accidental electrocution.

Prevention:

Replace the refrigerator's water filter every 6 months to prevent mineral buildup in the water line and inlet valve. Periodically check the freezer temperature to ensure it's within the recommended range.

Expert Tip:

Some Amana refrigerators have a forced harvest cycle. Locate the test button on the ice maker module (usually underneath) and press and hold it for a few seconds. This will initiate a harvest cycle. Observe if the ice maker attempts to eject ice. If it does, the issue may be related to water supply; if it doesn't, the ice maker module is likely faulty.

Frequently Asked Questions

•How do I force the ice maker to start a harvest cycle on my Amana refrigerator?

Locate the test button on the ice maker module, usually underneath. Press and hold it for 3-5 seconds to initiate a forced harvest cycle. Listen for the motor engaging and the ice ejector arm moving.

•What is the proper way to thaw a frozen fill tube in my Amana refrigerator?

Use a hair dryer on the lowest heat setting, directing the airflow towards the fill tube. Avoid using a heat gun or excessive heat, as this can damage the tube or surrounding components. Alternatively, you can use a steamer.

•How can I test the water inlet valve on my Amana refrigerator to see if it is functioning correctly?

Disconnect the water line from the inlet valve. Carefully apply 120V AC to the valve's terminals (using jumper wires and being extremely cautious). Observe if water flows through the valve when energized. If no water flows, the valve is likely defective.
