What is the most common problem with an LG refrigerator?
The most common problem we see with LG refrigerators like model LSXS26366S is a cooling problem (refrigerator or freezer not staying cold). When cooling is weak, you may also notice soft ice, thawing food, or longer run times; the next most common complaints are ice maker and water dispenser issues.
What to check first (fast, no tools)
- Confirm the control settings were not accidentally changed.
- Make sure both doors fully close and seal all the way around.
- Avoid overpacking; blocked vents cause warm spots and frost.
- Listen for fan noise inside the freezer; no airflow often means a fan or frost issue.
- Check for heavy frost or ice buildup that can restrict airflow.
Common symptoms and what they usually point to
| Symptom | Most likely area | What we recommend |
|---|---|---|
| Fresh food warm, freezer OK | Airflow from freezer to fridge | Clear vents, check for frost buildup, verify door seal |
| Freezer warm and fridge warm | Sealed system or compressor-related cooling | Have cooling system checked; parts may include compressor |
| Ice maker not making ice | Water supply, filter, ice maker | Replace filter, verify water flow, inspect ice maker |
| Slow water dispensing | Water filter or inlet valve | Replace filter, check supply pressure |
Parts that commonly relate to these problems on LSXS26366S
Cooling and water issues often trace back to a few high-impact components:
- Refrigerator compressor TCA38091801 (cooling system performance)
- LG refrigerator water filter ADQ73613401 (water flow and ice quality)
- LG refrigerator ice maker AEQ73209906 (no ice or intermittent ice)
Why it matters
Cooling problems can quickly lead to food spoilage, and water system restrictions can cause weak dispensing and poor ice production. Addressing airflow, door sealing, and filtration early prevents bigger performance issues.
Helpful model-specific guidance
Your LSXS26366S manual includes troubleshooting steps and Smart Diagnosis instructions that can help narrow down cooling and ice dispenser issues before replacing parts; see the LSXS26366S owner's manual.

What is the lifespan of an LG refrigerator?
Most LG refrigerators, including the LG LSXS26366S side-by-side refrigerator, typically last 10 to 15 years with normal use and basic maintenance. Keeping airflow clear, cleaning coils, and staying on top of water filter changes helps you reach the upper end of that range; see the LSXS26366S owner's manual for care guidance.
Typical lifespan and what affects it
A refrigerator’s life depends most on heat management, door sealing, and how hard the sealed system works.
- Condenser cleanliness: dusty coils make the compressor run hotter and longer
- Door gasket condition: air leaks cause longer run times and temperature swings
- Room conditions: hot garages and tight enclosures shorten life
- Ice and water system upkeep: clogged filters reduce flow and strain components
- Loading habits: overpacking blocks vents and reduces cooling efficiency
Maintenance checklist that extends life
We recommend these routine steps for LSXS26366S-STYLE LG side-by-side units:
- Vacuum and brush the condenser area every 6 to 12 months
- Keep doors closing easily; clean and inspect the gasket for gaps
- Replace the water filter on schedule; use the correct LG refrigerator water filter ADQ73613401
- Leave space behind and above the cabinet for ventilation
- Keep freezer and fresh food vents unblocked by food packages
Quick reference: lifespan vs. common symptoms
| What you notice | What it often points to | What to do first |
|---|---|---|
| Warm temps, long run times | Dirty condenser, airflow issue | Clean coils, confirm clearance |
| Frost buildup, weak cooling | Fan/defrost airflow problem | Check vents, listen for fan |
| Water dispenses slowly | Clogged filter or supply issue | Replace filter, purge air |
| Door won’t seal | Worn or warped gasket | Inspect and replace gasket if needed |
Why it matters
A refrigerator that runs hot or leaks air can still “work,” but it wears out the sealed system faster. Simple upkeep reduces compressor run time, stabilizes temperatures, and helps your LG refrigerator reach its full service life.

How big is the LG LSXS26366S?
The LG LSXS26366S side-by-side refrigerator measures 35.9 in. wide x 31.8 in. deep x 70.3 in. high. With the door opened, depth is 46.5 in. These are the exterior dimensions listed in the LSXS26366S owner's manual.
Dimensions at a glance
- Width: 35.9 in. (912 mm)
- Depth (doors closed): 31.8 in. (807 mm)
- Height: 70.3 in. (1785 mm)
- Depth (door open): 46.5 in. (1180 mm)
- Moving tip: removing doors reduces depth; confirm your exact “door removed” depth in the manual before delivery
Quick fit table (inches)
| Measurement | Size |
|---|---|
| Width | 35.9 |
| Depth (closed) | 31.8 |
| Height | 70.3 |
| Depth (door open) | 46.5 |
Why it matters for installation
Correct width, height, and door-swing depth prevent delivery issues and help maintain proper airflow around the compressor and condenser coil for reliable cooling.
What to measure before delivery
- Cabinet opening width at the front and back
- Overhead clearance for the full 70.3 in. height
- Door swing clearance using the 46.5 in. door-open depth
- Hallway and doorway widths on the delivery path
- Final placement clearances recommended in the LSXS26366S owner's manual
