LG LMX25964ST/02 refrigerator Parts

On an LG LMX25964ST bottom-mount refrigerator, leaking from the bottom is usually caused by a clogged defrost drain that overflows into the base, or a water supply leak to the dispenser or ice maker. We use the LMX25964ST manual to locate drain and water-line routing points for your exact configuration.

Quick checks that solve most bottom leaks

• Look for a sheet of ice or standing water under the crisper drawers (often a defrost drain issue).
• Check for a puddle that appears after using the dispenser or after an ice maker fill cycle (often a supply leak).
• Inspect the water line connection behind the refrigerator and the tubing path for kinks or rub-through.
• Verify the refrigerator is level; a forward tilt can encourage water to run out the front.
• If the leak is intermittent, note whether it happens during defrost (every several hours) or only when dispensing water.

Most common causes and what to do

What you see	Most likely cause	What we recommend
Water under crispers, then dripping to the floor	Defrost drain clogged or frozen	Clear the drain opening and flush with hot water; confirm the drain tube is open
Water near the back/bottom, especially after ice maker runs	Leaking water inlet valve or loose fitting	Inspect connections; replace the valve if it seeps or won’t fully shut off
Water trail along the cabinet base	Split or loose water tubing	Inspect and replace damaged tubing; secure routing to prevent rubbing
Water only after door is open a lot	Excess frost melt from air leaks	Check door seal seating and reduce humidity intrusion

Parts that commonly fix bottom leaks on this model

If you find a cracked line or a valve that seeps, these model-matched parts are common solutions:

• Refrigerator drain tube 5251JA3003D (helps when the drain path is restricted or deteriorated)
• Refrigerator water tubing MJU62070602 (for splits, pinholes, or rubbed-through tubing)
• Refrigerator water inlet valve AJU72992601 (for slow leaks, overfilling, or valve seepage)

Why it matters

A small leak can turn into floor damage, ice buildup under drawers, and poor cooling if water refreezes around the evaporator area. Fixing the drain or water supply leak early keeps defrost water flowing to the drain pan as designed.

For the LG LMX25964ST refrigerator, the most common service issue we see is a no-cool or weak-cool condition. The most frequent root causes are a sealed-system/compressor problem, restricted airflow from dirty condenser coils, or a failed fan or defrost component; start with the checks in the owner's manual.

Most common symptoms customers notice

• Refrigerator section warm but freezer still partly cold
• Both sections warm and food spoiling
• Clicking, buzzing, or repeated start attempts from the back of the unit
• Frost buildup on the rear freezer panel (airflow blocked)
• Ice maker or water dispenser performance drops (often tied to low cooling)

Quick checks we recommend before replacing parts

1. Confirm temperatures: set refrigerator to about 37°F and freezer to about 0°F; allow 24 hours to stabilize.
2. Clean airflow path: vacuum dust from the condenser area; blocked coils can mimic compressor trouble.
3. Listen for fans: the evaporator fan should run when cooling; a failed fan can cause warm temps.
4. Look for frost patterns: heavy frost suggests a defrost problem (heater, sensor, or control).
5. Check door sealing: gaps or torn gaskets cause long run times and poor cooling.

Parts that commonly relate to “not cooling” on this model

If your troubleshooting points to a specific failure, these are common matches for cooling complaints on LMX25964ST:

Symptom	Likely system	Example part on this page
Warm temps, loud clicking, won’t start	Compressor/start protection	Refrigerator compressor TCA38091801, refrigerator compressor overload protector 6750CL0001D
Runs a lot, poor cooling, hot cabinet sides	Heat rejection/airflow	Refrigerator condenser coil ACG73784701, refrigerator condenser fan motor assembly 4681JB1029D
Freezer frosts over, fridge warms	Defrost/evaporator airflow	Refrigerator defrost sensor assembly 6615JB2005N, LG refrigerator defrost heater 5300JK1005D, refrigerator evaporator fan motor 4681JB1027C

Why it matters

A refrigerator that cannot move heat efficiently (dirty coils, failed fan) or cannot create enough cooling (compressor or sealed-system issue) will run longer, warm up faster during door openings, and can lead to food spoilage. Catching airflow and defrost problems early often prevents bigger cooling failures.

Getting the right replacement part

We recommend matching parts by the full model number LMX25964ST and the symptom you’re seeing. You can order model-specific parts from the list for this refrigerator, or search by model on Sears PartsDirect.

The LG LMX25964ST is a 35 3/4-inch wide (36-inch class) French door, bottom-mount refrigerator with about 24.7 cu. ft. of total capacity. For exact height and depth (with and without handles) and required clearances, use the dimensions in the LMX25964ST owner's manual.

Key size specs to know

When customers ask about “size,” it usually includes these measurements and fit requirements:

• Width: 35 3/4 inches (often marketed as 36-inch class)
• Capacity: about 24.7 cu. ft.
• Depth: varies depending on handles and door position
• Height: varies with hinges and leveling legs
• Clearances: space needed for door swing, airflow, and water line routing

Measuring checklist (so it fits the first time)

Before you commit to placement, we recommend:

• Measure the opening width at the top, middle, and bottom
• Measure opening height to the lowest cabinet or trim point
• Measure opening depth and confirm handle clearance into walkways
• Confirm door swing space so drawers and bins can fully extend
• Plan room behind the unit for the water line; parts like refrigerator water tubing MJU62070602 help when replacing or rerouting a line

Planning ranges (helpful for rough layout)

Use these typical ranges for 36-inch class French door refrigerators to plan, then confirm exact numbers in the manual.

Measurement	Typical range	What affects it
Height	~68 to 71 in.	hinges, leveling
Depth	~29 to 36 in.	handles, door style
Recommended side clearance	~1/8 to 1/2 in.	door swing, cabinet fit

Why it matters

Accurate sizing prevents door interference, poor ventilation (which can reduce cooling performance), and installation issues like kinked water lines.
