Roper Refrigerator: Troubleshooting Small or Hollow Ice... | appliancefaults.com

Technical Background:

The Roper refrigerator's ice maker is controlled by the main control unit (MCU). The MCU monitors temperature and cycles the ice maker. The water inlet valve opens when the ice maker calls for water, filling the ice mold. Low water pressure or valve malfunction can cause insufficient fill, resulting in small or hollow ice.

Symptoms:

The Roper refrigerator is producing ice cubes that are smaller than usual or are hollow in the center. Ice production may also be slower than normal.

Possible Causes:

Low water pressure to the refrigerator
Clogged water filter
Frozen or restricted water supply line
Malfunctioning water inlet valve
Ice maker assembly issues
Low freezer temperature

Solution:

1

Check the water pressure to the refrigerator. It should be at least 20 PSI. If low, investigate plumbing issues.
2

Replace the water filter. A clogged filter restricts water flow. Use a new Roper-compatible filter.
3

Inspect the water supply line for kinks or freezing. Use a heat gun (low setting) to thaw any frozen sections.
4

Test the water inlet valve for proper function. Use a multimeter to check for continuity when the ice maker calls for water. The valve should have 120V AC applied during the fill cycle.
5

Examine the ice maker assembly for mineral buildup or damage. Clean with a solution of vinegar and water. Replace if necessary.
6

Verify the freezer temperature is between 0 and 10 degrees Fahrenheit. Adjust the temperature control if needed.
7

Check the fill tube for ice blockage. Use a hair dryer to thaw the ice.

Safety Warning:

Disconnect the refrigerator from the power supply (unplug it or turn off the breaker) before performing any repairs. Some components carry 120V AC, which can cause serious injury or death.

Prevention:

Replace the water filter every 6 months. Inspect the water supply line annually for kinks or damage. Clean the ice maker periodically with a solution of vinegar and water to prevent mineral buildup.

Expert Tip:

To manually initiate an ice harvest cycle, press and hold the ice maker feeler arm up for 10 seconds. This can help diagnose ice maker motor or module issues.

Frequently Asked Questions

•How do I test the water inlet valve with a multimeter?

Disconnect the power to the refrigerator. Locate the water inlet valve. Disconnect the wires from the valve. Set your multimeter to the ohms setting. Place the multimeter probes on the valve terminals. You should read a resistance value. An open circuit (no resistance) indicates a faulty valve.

•What type of water filter is compatible with my Roper refrigerator?

Refer to your refrigerator's user manual or the Roper website to identify the correct water filter model number. You can also find compatible filters by searching online using your refrigerator's model number.

•How do I access the water supply line connection at the back of the refrigerator?

Carefully pull the refrigerator away from the wall. Locate the water supply line connection, typically a 1/4-inch compression fitting. Before disconnecting the line, shut off the water supply to the refrigerator to prevent leaks.
