LG LMX25984SB/00 refrigerator Parts

To read an LG refrigerator model number, we match the letters and digits to the refrigerator style, size series, finish, and revision code. For your LG LMX25984SB, the model tag is typically found inside the fresh food compartment; confirm the exact characters on the rating label and in the LMX25984SB owner's manual.

Most LG refrigerator model numbers follow a pattern like this:

• Prefix letters identify the product family and configuration (for example, French door vs. top freezer).
• Middle digits usually indicate the capacity/series within that family.
• Finish letters often describe the exterior color or finish (for example, stainless look).
• Suffixes (such as /00) indicate a revision or production variation; this matters for parts compatibility.

We use the model and serial label to identify the exact parts list for your unit.

• Open the fresh food (refrigerator) doors and check the inside wall (commonly upper left area).
• Look for a rating label with MODEL and SERIAL.
• Write the model number exactly as shown, including any slashes or suffixes.
• If the label is worn, take a clear photo and zoom in to confirm each character.

Even when the main model number matches, a suffix can change which door parts, electronics, or water system parts fit.

After you confirm the full model from the label, order parts by matching the part ID to your model’s diagram and list. Common water and dispenser related parts for this model family include the refrigerator water filter 5231JA2006A and the refrigerator water inlet valve MJX41178908. You can also search by model number on Sears PartsDirect.

Using the exact model number (including any suffix) prevents ordering the wrong LG refrigerator parts and helps troubleshoot issues like no ice, weak water flow, or door alarm problems faster.

No. On the LG LMX25984SB refrigerator, the model number identifies the product series and configuration, not the exact manufacturing date. To determine the unit’s age, use the serial number (typically on the inside wall) and confirm the date format shown in the owner's manual.

• Locate the serial number label inside the fresh food compartment (commonly on a side wall or near the crisper area).
• Write down the full serial number exactly as shown.
• Use the serial number date code to determine the manufacturing month and year.
• Compare the manufacturing date to your purchase/installation date for a practical “age in service.”
• If the label is damaged or missing, check your purchase receipt or home records.

Knowing the manufacturing date helps us match the correct replacement parts and troubleshoot symptoms accurately. For example, if you’re diagnosing dispenser or ice maker issues, you may end up checking water system parts such as the refrigerator water inlet valve MJX41178908 or replacing the refrigerator water filter 5231JA2006A. You can order model-matched parts from the parts list for LMX25984SB, or search by model on Sears PartsDirect.

• If you’re working on a date-related service issue (like filter replacement intervals), follow the steps in how to replace the water filter in an LG refrigerator.
• If the control panel is showing a fault, use LG bottom freezer refrigerator error codes to narrow down the problem before replacing parts.

Cooling problems are the most common issue we see with LG refrigerators, including the LG LMX25984SB; symptoms include warm fresh food, soft ice, or temperature swings. Many “cooling” complaints trace back to airflow, fan, defrost, or control problems, and they can look similar even when the root cause differs.

• Refrigerator section warms up but freezer seems OK
• Freezer warms up and ice production drops
• Loud fan noise, rattling, or intermittent buzzing
• Frost buildup on the back wall or in the freezer
• Water leaking or puddles near the front of the unit

1. Confirm settings: Set fresh food to about 37°F and freezer to about 0°F (then allow 24 hours to stabilize).
2. Check door closure: Make sure doors fully close; this model uses an auto-closing hinge feature described in the LMX25984SB owner's manual.
3. Look for blocked vents: Avoid packing food tight against air returns and vents.
4. Listen for fans: If you do not hear normal airflow, the evaporator fan system is a common suspect.
5. Inspect for frost: Heavy frost often points to a defrost or airflow issue.

A refrigerator can “seem” like it has a compressor problem when the real issue is airflow (fan), defrosting (heater), or temperature feedback (sensor). Fixing the correct system first restores stable temperatures faster and helps prevent food spoilage.

• You smell burning insulation or see melted wiring
• The unit trips the breaker repeatedly
• You suspect a sealed-system repair is needed (special tools and training)

For model-specific operating features, troubleshooting steps, and specifications, use the LMX25984SB owner's manual. For parts ordering beyond the items listed here, search by model number on Sears PartsDirect.
