Amana Refrigerator: Troubleshooting Small or Hollow Ice... | appliancefaults.com

Technical Background:

The refrigerator's main control unit (MCU) controls the ice maker operation. The MCU energizes the water inlet valve based on signals from the ice level sensor and temperature sensors. Low water pressure or a faulty valve can lead to insufficient water filling the ice mold. A frozen water line restricts water flow. A failing ice maker module can also cause fill issues.

Symptoms:

The homeowner observes that the Amana refrigerator is producing ice cubes that are smaller than normal or are hollow in the center. Ice production may also be reduced.

Possible Causes:

Low water pressure to the refrigerator.
Clogged water filter.
Frozen or restricted water supply line.
Malfunctioning water inlet valve.
Ice maker assembly failure.

Solution:

1

Check the water pressure to the refrigerator using a pressure gauge connected to the water inlet valve (should be at least 20 PSI).
2

Replace the water filter with a new Amana-approved filter.
3

Inspect the water supply line for kinks or freezing. Use a hairdryer to thaw any frozen sections.
4

Test the water inlet valve for continuity using a multimeter. A reading of approximately 500-1500 ohms indicates a functioning valve. If open or shorted, replace the valve.
5

Manually cycle the ice maker. If no water enters the ice maker, further diagnose the valve or ice maker module.
6

Measure the fill time of the ice maker using a timer. Excessive fill times indicate a weak valve or low water pressure. Typical fill time is 6-10 seconds.
7

Check the freezer temperature with a thermometer. It should be between 0-10 degrees Fahrenheit.

Safety Warning:

Disconnect power to the refrigerator at the breaker panel before performing any repairs. Use proper Lock Out/Tag Out (LOTO) procedures. Some components may carry 120V AC.

Prevention:

Replace the water filter every 6 months. Check the water supply line annually for kinks or damage. Periodically clean the ice maker assembly with a damp cloth.

Expert Tip:

Some Amana refrigerators have a service mode. Locate the tech sheet for your model. Common test point locations are on the main control board. Entering the service mode allows you to manually activate components like the water inlet valve for testing.

Frequently Asked Questions

•How do I access the water inlet valve on my Amana refrigerator?

The water inlet valve is typically located at the back of the refrigerator, near the bottom. You may need to remove a rear access panel to reach it. Disconnect the water line and electrical connections before removing the valve.

•What is the proper water pressure for an Amana refrigerator ice maker?

The ideal water pressure is between 20 and 120 PSI. If the pressure is below 20 PSI, the ice maker may not fill properly.

•How do I manually cycle the ice maker on my Amana refrigerator?

Consult your refrigerator's service manual or tech sheet. Typically, there is a test button located on the ice maker module. Press and hold the button for a few seconds to initiate a test cycle. Be cautious of moving parts.
