Roper Refrigerator: Ice Cubes Stuck in Mold - Harvest... | appliancefaults.com

Technical Background:

The ice maker operates based on a timed cycle controlled by the ice maker module (essentially a small MCU). The module monitors freezer temperature and initiates a harvest cycle when the temperature is low enough. A heater warms the ice mold to release the cubes, and an ejector arm pushes the cubes into the ice bin. The water inlet valve refills the mold for the next cycle. This operation is 120V AC controlled.

Symptoms:

The ice maker in your Roper refrigerator is producing ice, but the cubes are stuck in the mold and the ice maker cannot complete its harvest cycle. You may notice a large block of ice or individual cubes frozen solid in the mold.

Possible Causes:

Low freezer temperature.
Defective ice maker thermostat.
Faulty ice maker module.
Water valve malfunction causing overfilling of the ice mold.
Mineral buildup in the ice mold.
Ice maker heater failure.

Solution:

1

Unplug the refrigerator or turn off the breaker to the fridge.
2

Remove the ice maker cover (typically secured with screws or clips, use a 1/4-inch nut driver).
3

Inspect the ice maker module for visible damage or ice buildup.
4

Manually force a harvest cycle by locating the test button (often underneath the ice maker) and pressing and holding it until the ice maker motor starts. Observe if the ice ejector arm moves.
5

If the arm does not move, check the ice maker heater. Using a multimeter, test for continuity across the heater terminals. No continuity indicates a failed heater.
6

If the heater tests good, suspect a faulty ice maker module. Replace the module with a new one.
7

If the ice maker overfills, check the water inlet valve solenoid using a multimeter. Resistance should typically be between 200-500 ohms. Replace if open or shorted.

Safety Warning:

Always disconnect power to the refrigerator before performing any repairs. Use proper Lock-Out/Tag-Out (LOTO) procedures to prevent accidental energizing of the circuit. High voltage is present in the ice maker circuit.

Prevention:

Periodically clean the ice maker mold with a mild solution of vinegar and water to prevent mineral buildup. Ensure the freezer temperature is set correctly (around 0 degrees Fahrenheit).

Expert Tip:

Many Roper refrigerators have a service mode accessible through a specific sequence of button presses on the control panel. Accessing this mode allows you to run diagnostics on various components, including the ice maker. Consult the service manual for the exact button sequence.

Frequently Asked Questions

•How do I test the ice maker thermostat?

Use a multimeter to check for continuity at room temperature and again after cooling the thermostat. The thermostat should be closed (showing continuity) at low temperatures and open (no continuity) at room temperature.

•What is the correct freezer temperature setting for optimal ice maker operation?

The ideal freezer temperature is around 0 degrees Fahrenheit. Colder temperatures can cause the ice to freeze too solid in the mold, preventing proper harvest.

•How do I locate the ice maker test button if it's not easily visible?

The test button is usually located on the underside of the ice maker module, often recessed. You may need to use a small screwdriver or probe to press it. Refer to the ice maker diagram for your specific model if needed.
