LG LFX25973ST/02 bottom-mount refrigerator Parts

For the LG LFX25973ST refrigerator, the limited warranty (USA) covers parts and labor for 1 year from the original retail purchase date; the sealed system is covered for 7 years (parts only), and the linear compressor is covered for 10 years (parts only). See the LFX25973ST owner's manual for the full warranty terms.

Here is the warranty breakdown shown in the warranty section:

These steps help you confirm eligibility and avoid delays:

• Locate your proof of original retail purchase (receipt or invoice).
• Write down the model and serial number from the refrigerator’s ID label.
• Confirm the purchase date and that the unit has been used under normal home conditions.
• Review exclusions and requirements in the LFX25973ST owner's manual (for example, what is considered normal operation).
• If you need help identifying a covered component, contact Sears PartsDirect support.

Warranty coverage changes by component. For example, a cooling failure tied to the sealed system or compressor can have different coverage (parts-only) than a general refrigerator issue (parts and labor for 1 year). Knowing which system is involved helps you plan the next step.

A bottom leak on your LG LFX25973ST is usually caused by a clogged or frozen defrost drain that overflows into the base, or a water-supply issue to the ice maker or dispenser (leaking valve, tubing, or connection). Use the owner's manual to locate access points and follow safe service steps.

• Defrost drain clogged: Water from normal defrosting cannot flow to the drain pan, so it spills into the cabinet and out the bottom.
• Drain tube issue: The external drain tube can be loose, restricted, or misrouted.
• Ice maker fill leak: A small crack or loose fitting can drip and run down to the bottom.
• Water inlet valve seep: The valve can weep slowly even when not dispensing.
• Door seal air leak: Warm air intrusion creates excess frost, which later melts and overwhelms the drain.

1. Confirm the liquid: If it is clear and near the front, it is often defrost water; if it is near the back by the wall connection, it is often supply-line related.
2. Inspect the freezer floor: A sheet of ice on the freezer bottom strongly points to a defrost drain problem.
3. Check the drain pan area: Look for cracks, overflow, or a pan that is out of position.
4. Inspect water connections: Look for wet fittings at the valve, tubing, and ice maker fill area.
5. Check door closing and gasket contact: Look for gaps, tears, or areas that do not seal.

A continuing leak can lead to ice buildup, poor cooling airflow, and water damage around the refrigerator. Fixing the root cause (drain restriction vs. water supply leak) prevents repeat puddles and helps the compressor and fans run normally.

• Follow our step-by-step tips in how to get rid of refrigerator puddles to narrow down whether the leak is defrost-related or plumbing-related.

For LG bottom-mount refrigerators like model LFX25973ST, the most common issue we see is a cooling complaint (fridge or freezer not staying cold). Many “not cooling” calls trace back to airflow restrictions, fan operation, or temperature sensing; use the owner's manual to match symptoms and normal noise descriptions.

• Fresh food section warm while freezer seems closer to normal
• Freezer warming up; ice production slows or stops
• Temperature swings (food freezing, then warming)
• Fan noise gets louder, or you do not hear the fan running
• Clicking, rattling, gurgling, or whooshing (some can be normal)

• Set controls correctly; allow 24 hours after changes for temperatures to stabilize.
• Keep interior vents clear; do not pack food tightly against air outlets.
• Confirm doors close fully and seals are clean and making full contact.
• Listen for airflow from the evaporator fan in the freezer area.
• Make sure the cabinet is level and not vibrating against a wall or cabinet.

Cooling problems can spoil food, reduce ice production, and increase run time. Fixing airflow or sensing issues early helps the refrigerator maintain stable temperatures and reduces strain on major components.
