Admiral Refrigerator Ice Maker Not Working:... | appliancefaults.com

Technical Background:

The ice maker's Main Control Unit (MCU) controls the ice-making process. When the arm is down, the MCU should initiate a cycle. This cycle involves energizing the water inlet valve (typically 120V AC), filling the ice mold, freezing the water, ejecting the ice, and repeating. Voltage paths involve the door switch (which inhibits ice making when the door is open), the thermostat (to ensure proper freezer temperature), and the ice maker module itself.

Symptoms:

The ice maker arm is in the down (on) position, but the ice maker is not producing any ice. The freezer seems cold enough, and the water supply is connected.

Possible Causes:

Faulty ice maker module: The module may not be initiating the ice-making cycle.
Water inlet valve malfunction: The valve may be blocked or not opening when energized.
Frozen fill tube: Ice buildup can prevent water from reaching the ice maker.
Low freezer temperature: If the freezer is not cold enough, the ice maker will not cycle.
Door switch issue: A faulty door switch might be preventing the ice maker from operating, even if the door is closed.
Clogged water filter: A clogged filter restricts water flow.

Solution:

1

Turn off the refrigerator at the breaker panel.
2

Remove the ice maker cover (usually held by screws or clips, often requires a 1/4-inch nut driver).
3

Check the freezer temperature with a thermometer. It should be between 0-10°F.
4

Inspect the fill tube for ice blockage. Use a hair dryer on low setting to melt ice if present.
5

Test the water inlet valve using a multimeter. Disconnect the wires and check for continuity when the ice maker cycles. If no continuity, replace the valve. Also, check for 120V AC at the valve during the fill cycle.
6

Force cycle the ice maker by locating the test points on the module (often marked T and H) and using a jumper wire. Observe if the ice maker goes through a full cycle.
7

If the ice maker does not cycle or the motor is not running, replace the ice maker module.

Safety Warning:

Disconnect power to the refrigerator at the breaker panel before working on it. Lock Out Tag Out (LOTO) procedures must be followed. Some components carry 120V AC. Exercise extreme caution.

Prevention:

Replace the water filter every 6 months. Periodically inspect the fill tube for ice buildup. Ensure the freezer temperature is within the recommended range (0-10°F).

Expert Tip:

On some Admiral models, pressing and holding the ice maker test button for 3 seconds will initiate a diagnostic cycle. Check the service manual for specific details.

Frequently Asked Questions

•How do I locate the water inlet valve?

The water inlet valve is typically located at the back of the refrigerator, near the bottom. It's connected to the water supply line and has wires connected to it.

•Where is the water filter located on my Admiral refrigerator?

The water filter location varies depending on the model. It's usually inside the refrigerator compartment (top right or bottom) or behind the base grille at the front.

•What voltage should I expect at the water inlet valve during the fill cycle?

You should expect to see approximately 120V AC at the water inlet valve terminals when the ice maker is calling for water during its cycle.
