LG LRFXC2416S Refrigerator: Craft Ice Spheres Small or... | appliancefaults.com

Technical Background:

The refrigerator's Main Control Unit (MCU) controls the craft ice maker. The MCU opens the water inlet valve based on signals from the thermistor and fill sensors. If the water pressure is low, or the inlet valve is malfunctioning, it won't fill the ice mold completely, leading to small or hollow ice spheres. The voltage path includes 120V AC to the water inlet valve, controlled by a relay on the main board.

Symptoms:

The LG LRFXC2416S refrigerator is producing craft ice spheres that are smaller than normal or have a hollow center.

Possible Causes:

Low water pressure to the refrigerator.
Frozen or restricted water supply line.
Faulty craft ice maker assembly.
Defective water inlet valve.
Incorrect freezer temperature setting.

Solution:

1

Verify water pressure to the refrigerator using a pressure gauge. It should be at least 30 PSI.
2

Inspect the water supply line for kinks or freezing. Thaw any frozen sections with a hairdryer (low setting) or replace the line.
3

Check the freezer temperature. It should be set to 0°F. Adjust if necessary.
4

Access the craft ice maker assembly. Disconnect power to the refrigerator at the breaker panel first. Use a 1/4-inch nut driver.
5

Examine the ice maker mold for mineral buildup or damage. Clean with a mild solution of vinegar and water.
6

Test the water inlet valve using a multimeter. It should read approximately 300-500 ohms. If the resistance is outside this range, replace the valve.
7

If the ice maker continues to produce small or hollow ice, replace the craft ice maker assembly.

Safety Warning:

Always disconnect power to the refrigerator at the breaker panel before performing any repairs. Follow Lock Out/Tag Out (LOTO) procedures to prevent accidental power restoration. The refrigerator operates on 120V AC, which can cause serious injury or death.

Prevention:

Replace the refrigerator's water filter every 6 months. Periodically inspect the water supply line for kinks or damage. Clean the ice maker mold every 3 months with a mild vinegar and water solution to prevent mineral buildup.

Expert Tip:

Enter the refrigerator's service mode by pressing and holding the Freezer and Refrigerator buttons simultaneously for 5 seconds. Navigate to the ice maker diagnostics to manually initiate a fill cycle and observe water flow.

Frequently Asked Questions

•What is the part number for the craft ice maker assembly on the LRFXC2416S?

The part number for the craft ice maker assembly on the LRFXC2416S is AEQ73996304.

•How do I manually defrost the water line if it's frozen?

Disconnect power to the refrigerator. Locate the water line and gently apply heat using a hairdryer on the low setting. Do not use a heat gun or open flame. Monitor the line for thawing and clear any ice buildup.

•What should the water filter pressure be after replacing it?

After replacing the water filter, the water pressure should return to the normal range, typically above 30 PSI. If the pressure remains low, inspect the filter housing for proper installation and check the water supply line for any obstructions.
