For the LG LSXS26366S side-by-side refrigerator, the most common customer-reported issue is a cooling problem (refrigerator or freezer not staying cold). In many cases, the root cause is in the sealed system or compressor-related components, but airflow, door sealing, and defrost issues can create similar symptoms; use the owner's manual troubleshooting section to narrow it down.

• Confirm both doors fully close and are not held open by bins or food packages.
• Look for frost buildup or ice fragments around the dispenser chute; clear the chute and make sure doors are closed before dispensing.
• Make sure air vents inside the compartments are not blocked by food.
• If the unit was unplugged, wait at least 5 minutes before plugging it back in.
• Listen for unusual clicking or buzzing along with warm temperatures (often points to a cooling-system problem).

Cooling complaints usually fall into a few buckets. These parts on our LSXS26366S parts list match the most common repair paths:

A “not cooling” complaint can be caused by something simple (blocked vents, doors not sealing) or something major (sealed system). Checking the easy items first prevents unnecessary parts replacement and helps you decide whether you are dealing with an airflow/defrost issue versus a compressor or sealed-system issue.

• Follow the step-by-step filter and flow tips in how to replace the water filter in an LG refrigerator.
• If you suspect dispenser or ice maker trouble, use how to prevent water dispenser and ice maker problems to reduce repeat clogs and freezing.

Your LG side-by-side refrigerator’s model number is printed on the model and serial number label inside the refrigerator compartment. On LSXS26366S units, you will typically see the model name format “LSXS26366*” on that label; use the exact characters shown.

• Open the fresh food (refrigerator) door and look along the inside walls near the front frame.
• Check near the crisper area or side wall inside the refrigerator compartment.
• Look for a label that includes both model and serial information.
• Do not remove or cover the model/serial label; it is used for parts matching.

The owner’s manual notes that the refrigerator has a model and serial number label inside the refrigerator compartment. The model name may include an asterisk for color (example format: LSXS26366*).

• Match the model number exactly as printed (letters and numbers).
• If you see a model family with an asterisk (LSXS26366*), use the full model shown on your label for ordering.
• Use the model number when selecting parts like the LG refrigerator water filter ADQ73613401 or an ice maker.

LG refrigerators often share similar designs across model families; the exact model number on the label is what ensures the right refrigerator water filter, door gasket, control board, or ice maker matches your specific build.
