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

Technical Background:

The refrigerator's main control unit (MCU) governs the operation of the ice makers. Voltage is supplied to the ice maker through a series of relays and sensors. If the MCU detects a fault or the voltage path is interrupted, the ice makers will not function. Power outages can cause voltage spikes that damage the control board or other components.

Symptoms:

The dual ice makers in my Frigidaire refrigerator stopped working after a recent power outage. No ice is being produced in either the upper or lower ice maker compartments. The freezer is cold, and the refrigerator seems to be cooling properly, but the ice makers are completely unresponsive.

Possible Causes:

Power surge damage to the ice maker control board.
Frozen water line due to prolonged cold during the outage.
Ice maker stuck in a harvest cycle.
Tripped ice maker overload protection.
Damaged wiring harness or connector to the ice maker.
Faulty water inlet valve.

Solution:

1

Unplug the refrigerator or turn off the breaker. Verify zero voltage with a multimeter.
2

Check the water supply line to the refrigerator for kinks or freezing. Ensure water pressure is at least 20 PSI.
3

Remove the ice maker cover (usually with a 1/4-inch nut driver) and inspect the wiring harness for damage or loose connections.
4

Using a multimeter, test for 120V AC at the ice maker power input connector when the ice maker should be cycling. If no voltage is present, trace back to the control board.
5

Manually cycle the ice maker using the test button (if equipped) or by manually turning the ice maker gear. Observe for any movement or abnormal sounds.
6

If the water inlet valve is suspected, test its resistance using a multimeter. An open or shorted valve indicates a replacement is needed.
7

If the control board is suspected, visually inspect it for burned components or water damage. Replacement might be necessary.

Safety Warning:

Always disconnect power to the refrigerator before performing any repairs. High voltage is present in the control board and wiring. Use proper Lock-Out/Tag-Out (LOTO) procedures to prevent accidental energization.

Prevention:

Install a surge protector on the refrigerator's outlet to protect it from power surges. Periodically check the water filter and replace it as needed to maintain adequate water flow. Inspect the ice maker for ice buildup and clear it as needed.

Expert Tip:

Some Frigidaire models have a service mode that can be accessed by pressing and holding certain buttons on the control panel. This mode allows you to run diagnostic tests on the ice maker and other components. Consult the service manual for the specific button combination for your model.

Frequently Asked Questions

•Where is the ice maker control board located?

The ice maker control board is typically located behind the refrigerator, near the compressor, or inside the refrigerator compartment, often behind a panel.

•What is the proper resistance reading for the water inlet valve?

The resistance reading for the water inlet valve usually ranges from 200 to 500 ohms. Consult the service manual for the specific value for your model.

•How do I manually start the ice maker harvest cycle if there is no test button?

You can manually start the harvest cycle by carefully rotating the ice maker's gear until the ejector arm begins to move. Be cautious not to force anything.
