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

Technical Background:

The ice maker control unit (MCU) signals the water inlet valve solenoid to open, allowing water to flow into the ice mold. A thermistor monitors the ice mold temperature. If the solenoid fails to open, or stays open too long, it can lead to freeze-ups. The 120V AC is supplied to the solenoid through a relay controlled by the MCU.

Symptoms:

The ice maker is freezing up, producing little to no ice. Ice cubes may be small or misshapen, or a solid block of ice forms in the ice maker.

Possible Causes:

Faulty water inlet valve solenoid
Low water pressure to the refrigerator
Clogged water filter
Ice buildup in the fill tube
Defective ice maker module

Solution:

1

Disconnect power to the refrigerator at the breaker panel.
2

Locate the water inlet valve, typically at the lower rear of the refrigerator.
3

Using a multimeter, check the solenoid coil for continuity. A normal reading is typically between 200-500 ohms. An open circuit indicates a faulty solenoid.
4

Reconnect power and carefully check for 120V AC at the solenoid terminals when the ice maker calls for water. Use extreme caution. No voltage indicates a problem with the ice maker module or wiring.
5

If voltage is present but no water flows, the solenoid is likely mechanically stuck or blocked.
6

Disconnect the water line from the valve and check the water pressure. It should be at least 20 PSI.
7

Replace the water inlet valve if the solenoid is faulty or if it is receiving voltage but not dispensing water.

Safety Warning:

Disconnect power to the refrigerator before performing any repairs (LOTO). 120V AC is present at the water inlet valve. Use extreme caution when testing.

Prevention:

Replace the water filter every 6 months. Periodically check the water pressure to the refrigerator. Inspect the ice maker fill tube for ice buildup.

Expert Tip:

GE Profile refrigerators have a service mode that allows you to manually activate the ice maker water fill cycle. Refer to the technical service manual for the specific key sequence for your model. This bypasses the normal ice-making cycle and allows for direct testing of the water valve.

Frequently Asked Questions

•What is the correct resistance range for the water inlet valve solenoid on my GE Profile refrigerator?

The typical resistance range for a GE Profile water inlet valve solenoid is between 200 and 500 ohms. However, it is always best to refer to the service manual for your specific model.

•How do I check the water pressure going to my refrigerator?

You can use a water pressure gauge with a hose adapter to connect to the water line going into the refrigerator. The pressure should be at least 20 PSI.

•Where can I find the service manual for my GE Profile refrigerator?

You can usually find the service manual online by searching for your specific model number followed by 'service manual' or 'technical sheet'. Some manufacturers also have the manuals on their website. If not, you can contact GE directly.
