LG LMXC23746D/00 refrigerator Parts

On the LG LMXC23746D, ice building up on the freezer floor is most often caused by a defrost drain that is partially or fully blocked; defrost water cannot flow to the drain pan, so it refreezes at the bottom. Use the steps in the LMXC23746D manual to safely access and clear the drain area.

• Unplug the refrigerator before removing freezer drawers or panels.
• Look for a solid “sheet” of ice on the freezer floor (classic drain issue).
• Check for water dripping into the freezer after a defrost cycle.
• Make sure food packages are not blocking rear vents or the drain trough.
• Confirm the freezer door closes fully and the gasket seals all the way around.

1. Manually defrost the freezer floor: Remove food, drawers, and let the ice melt (towels help). Do not chip ice with sharp tools.
2. Clear the drain path: Once the ice is melted, flush the drain opening with warm water (a turkey baster works well) until it flows freely.
3. Check the drain tube and drain pan: If the tube is restricted or damaged, replacing the drain tube assembly is a common repair on bottom-mount designs.

If you suspect the drain tube is the issue on this model, use the compatible refrigerator drain tube assembly 5251JA3004E.

When the drain can’t move water to the drain pan, the freezer repeatedly refreezes that water. Over time, the ice can interfere with airflow, cause temperature swings, and lead to leaks when it finally melts.

Yes. On the LG LMXC23746D, the ice maker is supplied by the refrigerator’s water system, so the same refrigerator water filter that filters dispenser water also filters the water used to make ice (there typically is not a separate “ice maker-only” filter). See the LMXC23746D manual for your filter location and replacement notes.

In most LG bottom-mount and French door designs like the LMXC23746D, water flows in this order:

• Home water supply line
• Water inlet valve
• Refrigerator water filter
• Dispenser and ice maker fill circuit

That means improving ice taste and reducing sediment is mainly about keeping the main filter current.

For the LMXC23746D, the compatible refrigerator water filter listed for this model is the LG refrigerator water filter ADQ73613401.

If you are chasing odor issues (not water quality), the LG refrigerator air filter ADQ73214408 is the separate part that targets food odors.

• Dispense and discard several glasses of water to flush carbon fines.
• Dump the first 1 to 2 batches of ice after a filter change.
• If ice is hollow or small, purge air and confirm strong water flow at the dispenser.
• Replace the filter on schedule to prevent slow fill and off-taste.

A fresh water filter protects the ice maker fill circuit from sediment and helps keep ice tasting clean. A clogged filter can also reduce water flow, which can lead to slow ice production.

On the LG LMXC23746D refrigerator, the DH F code indicates the refrigerator is detecting a defrost heating failure (the defrost cycle is not melting frost as expected). When defrost heat fails, ice can build up on the evaporator and restrict airflow, causing poor cooling.

• Power reset: unplug the refrigerator (or turn off the breaker) for 5 minutes, then restore power.
• Check for airflow symptoms: weak airflow from vents, warmer fresh food section, or frost/ice on the back freezer panel.
• Make sure doors close and seal fully; warm air leaks can accelerate frost buildup.
• Confirm vents are not blocked by food packages.
• If you see heavy frost, move food to a cooler and allow a manual defrost (doors open) to temporarily restore airflow.

A DH F condition is usually tied to the defrost system (heater, sensors, wiring, or control). For this model’s parts list, a common component to check or replace is the defrost heater.

• Refrigerator defrost heater assembly MEE62805303

For control panel behavior, error code handling, and any model-specific reset steps, use the LMXC23746D manual.

Defrost problems are not just an “ice issue”; they can choke airflow across the evaporator, making the compressor run longer and causing temperature swings in both the freezer and fresh food sections.

If your LG LMXC23746D bottom-mount refrigerator has power but the bottom freezer is warm, the most common causes are an airflow problem (evaporator fan or heavy frost/ice buildup), a sealed-system/compressor problem, or a control/sensor issue. Use the LMXC23746D manual to confirm control settings and any displayed error codes.

• Make sure the freezer temperature is set correctly and not in a demo/showroom mode (if equipped).
• Confirm the freezer drawer is closing fully and the door gaskets are sealing.
• Listen for the evaporator fan in the freezer; you should typically hear airflow when the unit is running.
• Check for heavy frost on the freezer back wall (often points to a defrost problem).
• Verify the condenser area is not packed with dust and the unit has airflow behind it.

If troubleshooting points to a specific component, these are common matches for this model’s parts list:

• Refrigerator compressor TCA38091801: drives the sealed cooling system; failure can cause no cooling.
• Refrigerator condenser fan motor assembly EAU62025701: moves air across the condenser; if not running, cooling performance drops.
• Refrigerator evaporator fan motor EAU61524007: circulates cold air through the freezer and into the fresh food section.
• Refrigerator defrost heater assembly MEE62805303: helps prevent ice buildup that can block airflow.
• Refrigerator temperature sensor 6500JB2002E: feeds temperature data to the control system.

A warm bottom freezer can quickly lead to food spoilage, and continued operation with poor airflow (ice buildup or a stalled fan) can make the compressor run longer and strain the cooling system.
