Maytag Refrigerator Ice Maker Fill Tube Frozen: Thawing... | appliancefaults.com

Technical Background:

The refrigerator's Main Control Unit (MCU) manages the ice maker cycle, controlling the water inlet valve based on temperature sensors and timers. The MCU sends 120V AC to the water inlet valve to open it, allowing water to flow into the ice maker mold. If the valve isn't opening properly, or if the water flow is restricted, the fill tube can freeze.

Symptoms:

The ice maker isn't producing ice, or ice cubes are smaller than usual. You might hear the ice maker trying to cycle, but no water is entering. You may also notice ice buildup around the fill tube.

Possible Causes:

Low freezer temperature setting.
Faulty ice maker water inlet valve.
Clogged water filter restricting flow.
Defective ice maker heater.
Kinked or blocked water supply line.
Improperly sealed ice maker housing allowing excessive cold air in.

Solution:

1

Disconnect power to the refrigerator at the breaker panel.
2

Locate the ice maker fill tube; it's typically behind the ice maker module.
3

Use a hair dryer on a LOW setting to gently thaw the frozen fill tube. Avoid overheating plastic parts. DO NOT use a heat gun.
4

Alternatively, carefully use a turkey baster filled with warm (not hot) water to flush the fill tube.
5

Once thawed, inspect the water inlet valve (located typically at the back of the refrigerator) for continuity using a multimeter. A reading of approximately 200-500 ohms is normal; infinite resistance indicates a faulty valve. Replace if defective.
6

Replace the water filter; a clogged filter restricts water flow and can contribute to freezing.
7

Restore power and monitor ice maker operation. Check the water pressure to the refrigerator; it should be between 20-120 PSI.

Safety Warning:

Disconnect power to the refrigerator at the breaker panel before beginning any repairs. This appliance operates at 120V AC, which can cause serious injury or death. Lock Out/Tag Out (LOTO) procedures should be followed.

Prevention:

Replace the water filter every 6 months. Ensure the freezer temperature is set appropriately (typically around 0 degrees Fahrenheit). Regularly inspect the water supply line for kinks or damage.

Expert Tip:

Some Maytag refrigerators have a service mode that allows you to manually cycle the ice maker and test the water inlet valve. Accessing this mode usually involves pressing a specific sequence of buttons on the control panel. Refer to the service manual for your specific model.

Frequently Asked Questions

•How do I access the ice maker to inspect the fill tube?

Typically, you'll need to remove the ice bucket and any shelving obstructing the ice maker. Some ice makers are held in place by screws, while others have release clips. Refer to your owner's manual for specific instructions.

•Where is the water inlet valve located on my Maytag refrigerator?

The water inlet valve is generally located at the back of the refrigerator, near the bottom. You may need to remove an access panel to reach it. Trace the water line from the fill tube back to the valve.

•How often should I replace my refrigerator's water filter?

Most refrigerator manufacturers recommend replacing the water filter every 6 months, or sooner if you notice a decrease in water flow or ice production. A clogged filter can lead to ice maker problems and affect water quality.
