Admiral Refrigerator Dual Ice Maker Not Working After... | appliancefaults.com

Technical Background:

Admiral refrigerators use a main control board (MCU) to regulate all refrigerator functions, including ice maker operation. The MCU sends a 120V AC signal to the ice maker's water valve when ice production is needed. The ice maker itself also has a small control board which manages the ice making cycle. The power outage may have caused a surge that damaged either the main control board or the ice maker control boards.

Symptoms:

The homeowner reports that both ice makers in their Admiral refrigerator stopped producing ice after a recent power outage. There are no error codes displayed on the refrigerator's control panel.

Possible Causes:

Power surge damaged the ice maker control board.
Ice maker water valve is stuck closed.
Ice maker is frozen due to prolonged lack of use after power returned.
Wiring harness to the ice maker dislodged or damaged.
Main control board failure preventing ice maker operation.

Solution:

1

Unplug the refrigerator or turn off the breaker. Use a multimeter to verify no voltage is present at the wall outlet.
2

Locate the ice maker(s) inside the freezer compartment.
3

Inspect the wiring harness connected to each ice maker for any signs of damage or loose connections. Reconnect if necessary.
4

Locate the water inlet valve for the ice maker, usually at the back of the refrigerator. Use a multimeter to test for 120V AC when the ice maker is calling for water. If no voltage is present, the control board may be faulty.
5

If voltage is present at the valve, but no water is flowing, the valve may be stuck or frozen. Carefully try to thaw it with a hair dryer on a low setting.
6

Inspect the ice maker control board for any signs of burnt components. If damage is visible, replace the control board.
7

Restore power and monitor ice maker operation. Allow 24 hours for ice production to resume.

Safety Warning:

Disconnect power to the refrigerator at the breaker panel before performing any repairs. Electrical shock hazard exists. Lock Out/Tag Out (LOTO) procedures MUST be followed before servicing high-voltage appliances.

Prevention:

Install a surge protector on the outlet that powers the refrigerator to protect it from future power surges.

Expert Tip:

On some Admiral models, you can force a harvest cycle by pressing and holding the ice maker test button for 3 seconds. This helps to confirm if the ice maker motor is functional. The test button is usually located on the side of the ice maker.

Frequently Asked Questions

•How do I determine if the ice maker is calling for water?

You can usually hear the ice maker cycling. Listen for the motor turning and the valve opening. If you have access to wiring diagrams, you can pinpoint the specific wires that trigger the water valve and test for voltage using a multimeter during the ice-making cycle.

•What voltage should I expect to see at the ice maker water valve?

Typically, you should see 120V AC when the ice maker is calling for water. If you see a significantly lower voltage, there may be a problem with the main control board or the wiring harness.

•Where is the ice maker control board located?

The ice maker control board is usually located either on top of the ice maker assembly, or behind a small cover on the side. You will likely need to remove the ice maker to access it completely. Always disconnect power before attempting to access the control board.
