LG LFX25973D/01 bottom-mount refrigerator Parts

On the LG LFX25973D bottom-mount refrigerator (French door with a bottom freezer compartment), there is not one single “most common” problem we can confirm from model-specific information alone. The best approach is to match your symptom to the system involved, then verify checks and settings in the LFX25973D manual.

• Fresh food warm, freezer cold: restricted airflow, frost buildup on the evaporator cover, or a fan not moving air.
• Both sections warm: cooling system not running efficiently, condenser area clogged with dust, or a control issue.
• Ice maker not making ice: water supply issue, filter restriction, or an ice maker component problem.
• Water leaking: defrost drain restriction, loose water line connection, or a valve issue.
• New or loud noises: fan blade interference, failing fan motor, or vibration near the compressor area.

• Confirm temperature settings; allow 24 hours after changes.
• Make sure interior vents are not blocked by food packages.
• Check doors close fully and gaskets seal all the way around.
• Look for heavy frost on the freezer back panel (often points to defrost or airflow).
• Clean dust from the condenser area to improve heat release.

Symptom-based troubleshooting helps avoid replacing the wrong part. For example, “freezer cold but fridge warm” usually points to airflow or defrost issues, not the water filter or dispenser components.

On LG model LFX25973D, a leak from the bottom is most often caused by defrost water backing up from a clogged or frozen drain, or by a leak in the ice maker or water supply system that runs down and exits underneath. Use the LFX25973D manual for panel locations and safe access steps.

• Check where the water starts: under crisper drawers (fresh food) vs. freezer floor.
• Look for ice on the freezer floor; this commonly points to a defrost drain backup.
• Inspect the drain pan area (rear bottom) for overflow or a cracked pan.
• Check the water filter area for drips after dispensing.
• Watch the ice maker during a fill; splashing or a slow drip can travel down the cabinet.

During defrost, meltwater should flow through a drain opening into a tube and down to the drain pan. If that path is restricted by ice or debris, water can overflow inside the cabinet and leak out at the bottom.

• Unplug the refrigerator.
• Remove bins and drawers to access standing water or ice.
• Melt ice around the drain opening using warm air (hair dryer on low, keep it moving).
• Flush the drain with hot water using a turkey baster until it drains freely.
• Recheck after 24 hours for repeat puddles.

If the puddle appears after making ice or dispensing water, focus on these areas.

If you suspect the ice maker itself is leaking or overfilling, a model-compatible replacement to consider is the ice maker assembly (AEQ73110203) - refrigerator ice making component by LG AEQ73110203.

Bottom leaks can damage flooring and can also lead to recurring ice buildup and airflow problems if defrost water keeps backing up. Finding the source early helps prevent repeat puddles and secondary cooling issues.

On the LG LFX25973D, the “lower part” is typically the bottom freezer drawer area. If it is not cooling, the most common causes are poor airflow from a stalled fan, dirty condenser coils, or a defrost problem that restricts airflow with frost. Use the LFX25973D manual to locate vents and access panels safely.

• Confirm the freezer temperature setting was not raised.
• Make sure the freezer drawer closes fully and seals evenly.
• Check for packages blocking air vents inside the freezer.
• Listen for the evaporator fan running (often audible with the door switch held closed).
• Look for heavy frost on the rear interior panel, which can signal a defrost issue.
• Clean dust from the condenser area (often behind the lower front grille or at the rear).

Cold air has to move across the evaporator and through ducts. If airflow is weak, the lower freezer warms and the refrigerator section may also drift warmer.

If the fan is not running or is noisy, the refrigerator evaporator fan motor EAU65058315 is a common part to check for this model.

A solid frost blanket on the evaporator blocks airflow and reduces cooling.

If you see heavy frost, the heater circuit is one area to test; this model’s parts list includes the kenmore elite refrigerator defrost heater 5300JK1005Z.

Dirty condenser coils or a failed condenser fan can keep the sealed system from shedding heat, reducing cooling performance.

When the bottom freezer warms up, frozen food can thaw and the compressor may run longer than normal. Restoring airflow and keeping the condenser area clean helps cooling performance and efficiency.
