LG LFXS24623S/00 refrigerator Parts

If your LG LFXS24623S bottom-mount freezer is not freezing while the fresh-food section still feels cold, the most common causes are restricted airflow (often from frost buildup), a fan problem, or a compressor that is not running correctly. Start with settings and basic checks in the LFXS24623S manual.

Quick checks we recommend first

• Confirm the freezer is set near 0°F and the refrigerator near 37°F.
• Give the unit 24 hours after any setting change to stabilize.
• Make sure the freezer drawer closes fully and the door gaskets seal all the way around.
• Listen for the evaporator fan running when the doors are closed.
• Look for heavy frost on the rear freezer panel (a common sign of a defrost or airflow issue).

Model-matched parts to inspect if the freezer stays warm

These parts are listed for LG LFXS24623S and can directly affect freezing performance:

• Refrigerator compressor TCA38091801 (drives the sealed cooling system)
• LG refrigerator evaporator fan motor 4681JB1027C (circulates cold air through the freezer)

If you suspect a control issue, check the parts list for your model for compatible control components; control boards can vary by production version.

Symptom-to-cause guide

What you notice	Most likely area to check	What it usually means
Fridge cool, freezer warm	Airflow path, evaporator fan	Cold air is not moving through the freezer
Heavy frost on freezer back wall	Defrost system or door seal	Frost is blocking airflow across the evaporator
Clicking, then quiet	Compressor start or compressor	Compressor is struggling to start or stay running
Both sections warming	Compressor or sealed system	Cooling system is not producing enough cold

Why it matters

A freezer that is not freezing can spoil food quickly and can also cause longer run times that stress the compressor. Catching airflow and frost issues early often prevents more expensive cooling-system repairs.

If your LG LFXS24623S refrigerator isn’t making ice in the bottom freezer, the most common causes are a water supply restriction (filter or inlet valve), the ice maker being off or jammed, or freezer temperature and airflow problems that prevent the ice maker from cycling. Use the LFXS24623S manual to confirm ice maker settings and basic checks.

Quick checks we recommend first

• Confirm the ice maker is turned ON and the ice bin is fully seated.
• Make sure the freezer is cold enough; ice production slows or stops if temperatures rise.
• Break up and discard clumped ice; check for a cube jam at the ejector.
• Test the door dispenser (if equipped); normal water flow usually means the supply is on.
• Look for frost buildup or blocked vents that can restrict airflow.

Water supply problems (most common)

A weak fill or no fill is often caused by a clogged filter or a failing inlet valve.

• If water flow is slow, replace the filter; this model uses options such as the LG kenmore refrigerator water filter ADQ36006101.
• If the filter is fresh but the ice maker still won’t fill, inspect the inlet valve and supply line for kinks or freezing; a compatible valve listed for this model is the valve asy,wa 5221JB2010G.

Symptoms and what they usually mean

What you notice	Likely cause	What to do next
No ice and weak or no dispenser water	Supply shutoff closed, kinked line, restricted filter, or inlet valve issue	Check shutoff and line; replace filter; then test inlet valve
Water dispenses normally but no ice	Ice maker off, jammed, or not cycling	Turn on, clear jam, reset if applicable
Small or hollow cubes	Restricted filter or low water pressure	Replace filter; verify household pressure

Freezer temperature and airflow issues

Bottom-freezer ice production depends on steady cold air movement.

• Keep packages from blocking vents and the ice maker area.
• Heavy frost on the evaporator cover can indicate a defrost issue.
• If airflow seems weak, the fan may be failing; one listed option is the LG refrigerator evaporator fan motor 4681JB1027C.

Why it matters

Ice makers are sensitive to both water flow and freezer temperature. Fixing the root cause (filter restriction, inlet valve fill problem, or airflow) helps prevent hollow cubes, slow production, and repeat ice jams.

On the LG LFXS24623S bottom-mount refrigerator, the most common “problem” customers report is a cooling imbalance: the refrigerator section warms up while the freezer stays cold. This usually points to an airflow restriction, frost buildup from a defrost issue, or a temperature-sensing/control problem.

Quick checks we recommend first

• Make sure food packages are not blocking air vents in the fresh food section.
• Confirm both doors close fully and the gaskets seal all the way around.
• Set temperatures to normal and allow 24 hours for temperatures to stabilize.
• Listen for the evaporator fan; weak or no airflow often means a fan issue or ice blockage.
• Check for frost or ice on the rear freezer panel (a common sign of defrost trouble).

For model-specific control settings and operating guidance, use the LFXS24623S manual.

Likely causes by symptom

Symptom you notice	Most likely area	What to check next
Fridge warm, freezer cold	Airflow from freezer to fridge	Blocked vents, ice restricting ducts, evaporator fan not moving air
Frost buildup, weak airflow	Defrost system	Defrost heater, defrost sensor, ice behind the evaporator cover
Temps swing up and down	Temperature sensing	Sensor readings and wiring connections
Runs a lot, still warm	Heat rejection or sealed system	Condenser coil cleanliness, condenser fan operation, compressor performance

Parts that commonly relate to these symptoms on this model

If troubleshooting points to a failed component, these compatible parts are listed for LG LFXS24623S:

• LG refrigerator evaporator fan motor 4681JB1027C (moves cold air through the freezer and into the fresh food section)
• Refrigerator defrost sensor assembly 6615JB2005N (helps control defrost operation and prevents heavy frost)
• Refrigerator temperature sensor 6500JB2002E (reports compartment temperature to the controls)
• Refrigerator compressor TCA38091801 (circulates refrigerant; cooling problems can occur if it is failing)

Why it matters

When the freezer stays cold but the refrigerator warms up, food safety becomes the priority. Fixing airflow and defrost or sensor issues helps prevent spoilage, reduces run time, and avoids repeat icing.
