LG LSXS26366D/02 side-by-side refrigerator Parts

Cooling problems are the most common issue we see with LG refrigerators like model LSXS26366D; symptoms include warm fridge and freezer temperatures, food thawing, and longer run times. Many “not cooling” complaints trace back to airflow restrictions, dirty condenser areas, or a sealed-system/compressor problem.

Most common symptoms to watch for

• Fresh food section warm but freezer still partly cold
• Freezer warming up and ice production slowing or stopping
• Clicking, buzzing, or unusually loud running sounds
• Frost buildup that blocks vents and reduces airflow
• Water leaking or puddles near the front of the unit

Quick checks we recommend first (before replacing parts)

1. Confirm temperature settings and allow 24 hours after any adjustment.
2. Make sure doors fully close and seals are making contact all the way around.
3. Clear blocked air vents (don’t pack food tightly against rear vents).
4. Clean dust from the condenser area and verify the condenser fan is running.
5. If the unit has power but performance is inconsistent, use the built-in diagnostic steps in the LSXS26366D owner’s manual.

Common causes and what they typically affect

Likely cause	What you notice	What to check next
Dirty condenser area or poor airflow	Gradual warming, long run times	Clean and recheck temps in 24 hours
Door gasket not sealing	Frost, moisture, temp swings	Inspect gasket for gaps/tears
Water filter restriction	Slow water flow, weak dispenser	Replace filter and purge air
Compressor or sealed-system issue	Both sections warm, may be noisy	Professional diagnosis recommended

Parts that often come up in repairs

If troubleshooting points to a specific failure, these model-matched parts are commonly involved:

• Refrigerator compressor TCA38091801 (cooling and sealed-system performance)
• LG refrigerator water filter ADQ73613401 (water flow and dispenser performance)

Why it matters

A refrigerator that is even 5 to 10 degrees too warm can spoil food quickly and overwork major components like the compressor. Catching airflow and sealing issues early often prevents bigger cooling failures.

The LG LSXS26366D 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 about 46.5 in. For the exact clearance and installation spacing, follow the LSXS26366D owner’s manual.

Dimensions and clearance basics

Use these measurements to confirm fit through doorways and into the cabinet opening.

• Width: 35.9 in. (912 mm)
• Depth (doors closed): 31.8 in. (807 mm)
• Height: 70.3 in. (1785 mm)
• Depth with door open: 46.5 in. (1180 mm)
• Depth after door removal (for moving): commonly 29.1 in. (739 mm) for this model family

Quick size table

Measurement	Inches	Millimeters
Width	35.9	912
Depth (closed)	31.8	807
Height	70.3	1785
Depth (door open)	46.5	1180

Why it matters

Getting the size right prevents delivery day surprises and helps your LG refrigerator cool efficiently. Proper clearance improves airflow around the condenser area and makes it easier to open doors fully for shelves, bins, and the ice and water dispenser.

Tips before you buy or move it

• Measure the cabinet opening (width, height, and depth) and compare to the table above.
• Confirm door swing space; the door-open depth is the key number for tight kitchens.
• Measure your entry path (front door, hallways, turns).
• If needed, plan for door removal to reduce depth during moving.
• After installation, keep recommended clearances from the manual for ventilation.

Most LG refrigerators, including the LG LSXS26366D side-by-side, typically last 10 to 15 years with normal use and basic maintenance. A well-kept unit often reaches the upper end of that range, especially when airflow and temperatures are kept consistent.

What to expect for the LSXS26366D over time

Refrigerator lifespan is usually limited by cooling-system wear, airflow restrictions, and water/ice system issues. Your LSXS26366D owner's manual also outlines warranty coverage periods that can help you understand which major components are designed for long service life.

Common “age milestones” we see:

• Years 1 to 5: Most issues are setup, airflow, or water supply related.
• Years 6 to 10: Wear items and ice maker or dispenser components become more common.
• Years 10 to 15: Cooling performance problems are more likely; sealed-system repairs can be more frequent.

Maintenance that extends refrigerator life

These steps reduce strain on the compressor, evaporator, and condenser system:

• Keep condenser airflow clear; vacuum dust from the grille and surrounding area.
• Maintain door sealing; fix gaps, warping, or tearing before frost and run-time increase.
• Replace the water filter on schedule to protect the water valve and dispenser flow.
• Avoid overpacking; blocked vents cause warm spots and longer run times.
• Set stable temps (typical targets: 37°F fresh food, 0°F freezer).

Parts that commonly affect longevity

If performance drops, these model-matched parts are often involved:

• Refrigerator compressor TCA38091801 (core cooling component)
• Refrigerator condenser coil ACG73748502 (heat removal; airflow and cleanliness matter)
• LG refrigerator water filter ADQ73613401 (helps maintain water flow and taste)

Quick lifespan guide (typical)

Refrigerator type	Typical lifespan	What most often ends service life
Side-by-side (like LSXS26366D)	10 to 15 years	Cooling-system wear, airflow issues, control failures
Top freezer	12 to 18 years	Thermostat/control wear, sealed-system leaks
French door	10 to 15 years	Ice maker/water issues, electronics, cooling wear

Why it matters

A refrigerator that runs longer to hold temperature uses more energy and stresses sealed-system components. Simple upkeep (airflow, seals, filter changes) is the most reliable way to push an LG fridge toward its full expected lifespan.
