Admiral Refrigerator Ice Maker Overflow: Troubleshooting... | appliancefaults.com

Technical Background:

The refrigerator's MCU (Main Control Unit) controls the ice maker fill cycle by energizing the water inlet valve. The valve opens allowing water to flow into the ice maker tray. The MCU times this fill cycle. A faulty valve, clog or level sensor can cause an overflow.

Symptoms:

The homeowner observed that the ice maker in their Admiral refrigerator overflowed, causing ice to accumulate and freeze the ice bin guide in place. This prevents the ice bin from being easily removed.

Possible Causes:

Faulty water inlet valve not shutting off completely.
Defective ice maker module overfilling the ice tray.
Clogged or frozen fill tube restricting water flow then suddenly releasing too much water.
Low water pressure causing inconsistent fill times.
Ice maker not cycling properly due to a faulty thermostat or motor.

Solution:

1

Disconnect power to the refrigerator at the breaker panel. Verify 0V AC at the refrigerator outlet with a multimeter.
2

Locate the water inlet valve, usually at the back of the refrigerator. Disconnect the water supply line.
3

Test the water inlet valve with a multimeter for continuity. A lack of continuity indicates a faulty valve requiring replacement. Replace if needed.
4

Inspect the fill tube for ice blockage. Use a hair dryer on low setting to melt any ice. Be careful not to melt any plastic parts. Clear obstructions with warm water flush.
5

Examine the ice maker module. Check for any signs of physical damage or sticking parts. If the module appears defective, replace it.
6

Once repairs are completed, reconnect the water supply line and restore power to the refrigerator. Monitor the ice maker for proper operation over 24 hours.
7

Check the water pressure to the refrigerator. It should be between 20 and 120 PSI.

Safety Warning:

Always disconnect power to the appliance before performing any repairs. Lock Out Tag Out (LOTO) procedures should be followed. Some components may carry 120V AC. Use extreme caution when working near electrical components.

Prevention:

Replace the refrigerator's water filter every 6 months. Periodically check the ice maker for proper operation and any signs of leaks or overflows.

Expert Tip:

Many Admiral refrigerators have a diagnostic mode. Simultaneously pressing the 'Freezer Up' and 'Freezer Down' buttons for 3 seconds may initiate a self-test cycle. Consult the service manual for the specific model.

Frequently Asked Questions

•What is the resistance range I should expect when testing the water inlet valve?

Typically, a water inlet valve should have a resistance between 200 and 500 ohms. However, consult the specific model's service manual for the exact specifications.

•How do I access the ice maker module in my Admiral refrigerator?

Usually, the ice maker module is accessible by removing the ice bin and any surrounding trim pieces. It's often held in place by screws or clips. Refer to the service manual or online videos for your specific model.

•What type of water filter does my Admiral refrigerator use, and where is it located?

The water filter type and location vary by model. Common locations include the upper right corner of the refrigerator compartment, the base grille, or the back of the unit. Refer to your owner's manual or look for a filter access panel. Common filter types are push-and-turn or twist-and-lock.
