GE Profile Ice Maker Freeze-Up: Water Inlet Valve... | appliancefaults.com

Technical Background:

The Main Control Unit (MCU) sends a 120V AC signal to the water inlet valve solenoid when the ice maker calls for water. The solenoid opens, allowing water to flow into the ice maker mold. If the solenoid fails to open or close properly, or if the water supply is restricted, ice production will be affected.

Symptoms:

The homeowner reports the ice maker is not producing ice or is producing very little ice. Ice may be clumped together in a frozen mass. Water may be dripping or leaking inside the freezer compartment.

Possible Causes:

Defective water inlet valve solenoid.
Low water pressure to the refrigerator.
Clogged water filter.
Frozen or restricted water supply line.
Faulty ice maker module.
Damaged wiring harness to the valve.

Solution:

1

Disconnect power to the refrigerator at the breaker panel.
2

Locate the water inlet valve, typically at the rear of the refrigerator near the water supply connection. Access might require removing a rear panel using a 1/4-inch nut driver.
3

Disconnect the water supply line from the valve.
4

Using a multimeter, test the solenoid windings for continuity. A reading of infinity (open circuit) indicates a faulty solenoid. Resistance should typically be between 200-500 ohms.
5

Check voltage supply to the solenoid during an ice-making cycle. Expect to see 120V AC using a multimeter. Initiate a test cycle in service mode if necessary. Use insulated pliers when working with live voltage.
6

If voltage is present and the solenoid has no continuity, replace the water inlet valve. Use Teflon tape on all threaded connections.
7

Reconnect the water supply line and power up the refrigerator. Monitor ice production for 24 hours. Check for leaks.

Safety Warning:

Disconnect power to the appliance before performing any repairs. Use proper Lock-Out/Tag-Out (LOTO) procedures. High voltage is present in the control circuitry.

Prevention:

Replace the water filter every 6 months, or as recommended by the manufacturer. Inspect the water supply line for kinks or damage. Periodically check the ice maker for proper operation.

Expert Tip:

To force an ice maker cycle on many GE Profile models, press and hold the freezer light switch and the 'Ice Type' button simultaneously for 10 seconds. This will initiate a test cycle and allow you to observe the valve operation.

Frequently Asked Questions

•What is the correct resistance range for a typical GE ice maker water inlet valve solenoid?

A typical GE ice maker water inlet valve solenoid resistance range is between 200 and 500 ohms. An open circuit indicates a faulty solenoid.

•How do I access the service mode on my GE Profile refrigerator?

Service mode access varies depending on the specific model. Consult the technical service manual or search online using your model number. Common methods involve pressing specific button combinations for a set duration.

•What is the proper water pressure for a GE Profile ice maker?

The recommended water pressure for a GE Profile ice maker is typically between 40 and 120 PSI. Low water pressure can significantly impact ice production.
