LG LFX25974ST/03 refrigerator Parts

The LG LFX25974ST is a 36-inch class bottom-mount refrigerator with about 24.7 cu. ft. of total capacity. For the exact cabinet and door-clearance dimensions for your specific installation, we recommend confirming the measurements listed in the LFX25974ST owner's manual.

What “size” usually means (and what to check)

When customers ask about refrigerator size, we typically look at these specs:

• Width class: 36-inch
• Capacity: about 24.7 cu. ft.
• Fit requirements: door swing, handle depth, and ventilation clearance
• Delivery path: doorway and hallway width, plus turn clearance
• Water hookup space: room for the supply line behind the unit

Quick sizing guide for planning

Use this as a practical checklist before you buy parts, move the unit, or plan a kitchen change.

Measurement you need	Where it matters	What to do
Width (cabinet and doors)	Cabinet opening	Measure the opening at top, middle, bottom
Depth (with doors/handles)	Walkways, islands	Measure from wall to front-most point
Height	Upper cabinets	Measure floor to cabinet bottom
Door clearance	Door swing and drawer pull-out	Allow extra space on the hinge side

Why it matters

A refrigerator that is “36-inch class” can still require extra clearance for French doors, the freezer drawer, and the water line. Verifying the exact dimensions helps prevent door interference, poor airflow (warm temps), and pinched water tubing.

Related parts that can affect fit and sealing

If you are checking size because doors do not close or the unit is not sealing well, these model-matched parts can be involved:

• Refrigerator door gasket MDS64172919 (torn or warped gasket can mimic a fit problem)
• Refrigerator door stop 4620JJ2009A (can limit door travel)
• Refrigerator flipper assembly AGU75188619 (helps the French doors seal correctly)

For the LG LFX25974ST refrigerator, the compressor warranty is typically 10 years on parts and 5 years on labor (for the Linear/Inverter compressor). For the rest of the refrigerator, use the warranty statement included with your unit for the exact coverage terms and dates; see the LFX25974ST owner's manual.

What’s covered (at a glance)

Warranty coverage varies by component and by the warranty document that came with your refrigerator. These are the most common items customers check first:

• Compressor coverage (often longer than other parts)
• Sealed system related repairs (varies by warranty terms)
• Electronic controls and sensors (standard coverage varies)
• Dispenser and ice maker components (standard coverage varies)
• Cosmetic items and consumables (often limited or excluded)

Quick warranty summary table

Use this as a practical starting point, then confirm details in your paperwork.

Item	Typical coverage for this model line	What to do next
Linear/Inverter compressor	10 years parts; 5 years labor	Confirm eligibility dates in your warranty document
Other refrigerator components	Standard limited warranty (varies)	Check your warranty statement for term and exclusions
Consumables (filters, bulbs)	Often not covered	Replace as needed using the parts list for LFX25974ST

Why it matters

Warranty terms determine whether a cooling issue is handled as a sealed system or compressor-related repair versus a normal service repair. That affects both the parts involved and whether labor is included.

Parts that are commonly involved in cooling or compressor-related repairs

If you are troubleshooting a cooling problem (even if it is not warranty-related), these model-matched parts are commonly checked or replaced by a technician:

• Refrigerator compressor TCA38091801
• Refrigerator compressor overload protector 6750CL0001D
• Refrigerator filter dryer ADH73150208
• Refrigerator evaporator fan motor 4681JB1027C

If your LG LFX25974ST bottom freezer is not freezing, the most common causes are the freezer temperature not set cold enough, airflow blocked by frost or overpacking, or a cooling-system failure such as an evaporator fan, control board, or compressor problem. Set the freezer to 0°F first.

Start with settings and simple checks

The factory default for this model is 0°F for the freezer and 37°F for the refrigerator. After any adjustment, allow 24 hours for temperatures to stabilize; see the steps in the LFX25974ST owner's manual.

• Set the freezer to 0°F (or 1 to 2 degrees colder if needed)
• Make sure the display is not showing an OFF mode
• Confirm the freezer drawer closes fully and seals
• Do not overpack; leave space at vents for airflow
• Check for a thick frost layer on the back wall (airflow restriction)

What the symptoms usually point to

What you notice	What it often means	Example part for this model
Freezer is warm and you do not hear airflow	Evaporator fan not running	Refrigerator evaporator fan motor 4681JB1027C
Clicking near the compressor, starts then stops	Overload protector tripping	Refrigerator compressor overload protector 6750CL0001D
Temps swing or controls act erratically	Control board issue	Refrigerator electronic control board EBR73456502
Both sections warming over time	Compressor or sealed-system issue	Refrigerator compressor TCA38091801

Quick checks before replacing parts

• Clean dust from the condenser area so heat can dissipate
• Inspect the door gasket for gaps or tears; warm air leaks prevent freezing
• If you see heavy frost, defrost the unit fully and recheck cooling

Why it matters

A freezer that cannot hold 0°F will soften frozen food, cause ice to melt and refreeze, and can force longer run times that accelerate wear on the compressor and fans.
