What is the most common problem with the LG refrigerator?
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.
What you should check first (fast, no tools)
- 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).
Common causes and the parts that often relate
Cooling complaints usually fall into a few buckets. These parts on our LSXS26366S parts list match the most common repair paths:
| Symptom you notice | Likely system involved | Example part for this model |
|---|---|---|
| Not cooling or weak cooling | Sealed system / compressor | Refrigerator compressor TCA38091801 |
| Frost buildup, warming, then recovers | Defrost system | Refrigerator defrost heater 5300JB1114Z, refrigerator defrost sensor EBD61246710 |
| Warm temps plus poor heat removal | Condenser airflow / heat exchange | Refrigerator condenser coil ACG73748502 |
| Ice maker not making ice | Ice maker system / water supply | Refrigerator ice maker AEQ73130002 |
| Slow water, bad taste, dispenser issues | Filtration / water flow | LG refrigerator water filter ADQ73613401, refrigerator water inlet valve AJU34125558 |
Why it matters
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.
Helpful DIY guidance
- 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.

How do I find the model number on my LSXS26366S?
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.
Where to look (fastest checks)
- 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.
What the label looks like
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*).
| What you need | Example you might see | Why it matters |
|---|---|---|
| Model number | LSXS26366S (or LSXS26366*) | Ensures correct diagrams and parts fit |
| Serial number | A unique code | Helps identify production details |
Tips to avoid ordering the wrong part
- 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.
Why it matters
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.
For diagrams and additional identification details, use the LSXS26366S owner’s manual.
