Roper Fridge Ice Maker Water Valve Humming, No Water... | appliancefaults.com

Technical Background:

The ice maker module signals the main control unit (MCU) to open the water inlet valve. The MCU then sends 120V AC to the water inlet valve solenoid. If the valve is functioning correctly and water pressure is adequate, water will flow into the ice maker. A humming sound often indicates the solenoid is energized but the valve is not opening.

Symptoms:

The ice maker in your Roper refrigerator is not producing ice. You hear a humming sound coming from the back of the refrigerator, near where the water line connects, but no water is being dispensed into the ice maker tray.

Possible Causes:

Frozen water supply line.
Clogged water filter.
Defective water inlet valve.
Low water pressure to the refrigerator.
Faulty ice maker module.
Kinked or blocked water line.

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 line connection. Use a 1/4-inch nut driver or 5/16-inch socket to remove any access panels.
3

Using a multimeter, check for 120V AC at the water inlet valve terminals when the ice maker is calling for water. A non-contact voltage tester can also be used.
4

If 120V AC is present, disconnect the water line from the valve and check for water flow. If no water flows, the valve is likely defective. Use a bucket to catch any water.
5

If no voltage is present, inspect the ice maker module and wiring harness for damage. Check the continuity of the wiring harness with a multimeter.
6

Check the water pressure to the refrigerator, ensuring it is within the manufacturer's specifications (typically 20-100 PSI). A water pressure gauge can be installed on the water supply line.
7

Replace the water inlet valve if it is defective. Ensure the replacement valve is compatible with your Roper refrigerator model.

Safety Warning:

Always disconnect power to the refrigerator at the breaker panel before performing any repairs. Use appropriate safety precautions when working with electricity and water. Lock Out/Tag Out (LOTO) procedures should be followed to ensure the breaker remains off during the repair. High voltage is present in the control panel.

Prevention:

Replace the water filter every 6 months, or as recommended by the manufacturer. Periodically check the water supply line for kinks or damage. Monitor ice production and address any issues promptly.

Expert Tip:

Many Roper refrigerators have a service mode that allows you to manually activate the ice maker water valve. Refer to the refrigerator's service manual or online resources for the specific service mode entry sequence for your model. This can help confirm the valve's functionality.

Frequently Asked Questions

•How do I access the water inlet valve on my Roper refrigerator?

The water inlet valve is usually located on the back of the refrigerator, near the bottom. You may need to remove an access panel to reach it. The water line will be connected to it.

•What should the water pressure be for my refrigerator?

Most refrigerators require between 20 and 100 PSI of water pressure. Check your refrigerator's manual for the specific requirements.

•How do I test the ice maker module?

Testing the ice maker module usually involves checking its continuity and voltage outputs. Consult the service manual for your specific refrigerator model for detailed testing procedures. You can also visually inspect the module for any burnt components.
