LG LSXS26326B/02 side-by-side refrigerator Parts

Most LG refrigerators average 10 to 15 years of service life. For your LG LSXS26326B side-by-side refrigerator, lifespan depends most on sealed-system health (compressor, condenser, evaporator), airflow, and routine maintenance like cleaning and filter changes; see the LSXS26326B owner's manual for model-specific care guidance.

Typical lifespan ranges (what we see most often)

• Average expected life: 10 to 15 years
• Shorter life is more common when: condenser area is dusty, doors do not seal well, or the ice maker and dispenser are heavily used
• Longer life is more common when: temperatures are stable, coils stay clean, and water filtration is maintained

Item	Typical impact on lifespan	What to do
Compressor and sealed system	Highest	Keep airflow clear; address cooling issues early
Door gaskets and door alignment	Medium to high	Keep seals clean; replace worn gaskets
Water filter and water system	Medium	Replace filter on schedule; purge air after changes
Ice maker and dispenser	Medium	Prevent clogs and leaks; keep chute area clear

Maintenance that helps your LG LSXS26326B last longer

• Replace the water filter about every 6 months, or sooner if flow drops (a common cause of weak dispensing).
• Keep the refrigerator away from heat sources and keep ventilation openings clear.
• Clean spills promptly and unplug the refrigerator before cleaning.
• Watch for early symptoms (warming temps, loud fan noise, frost buildup, water leaks) and correct them before they strain the sealed system.

Helpful resources and parts for this model:

• How to change the water filter in an LG refrigerator
• LG refrigerator water filter ADQ73613401
• If you ever have sealed-system symptoms (not cooling, clicking, warm freezer), the compressor is a key component: refrigerator compressor TCA38091801

Why it matters

A refrigerator that is running hot, leaking air at the doors, or restricted by a clogged filter often runs longer and harder. That extra runtime increases wear on major components like the compressor and can shorten overall lifespan.

For the LG LSXS26326B side-by-side refrigerator, the most common customer-reported issue is a cooling failure (refrigerator or freezer not cold enough). The most frequent root causes are airflow and defrost-related problems, and in some cases a sealed-system or compressor problem that requires advanced service; use the troubleshooting steps in the owner's manual to narrow it down.

What you’ll usually notice first

• Fresh food section warming up while the freezer seems “okay” (or vice versa)
• Louder-than-normal running noises, clicking, or frequent cycling
• Frost buildup on the back wall or on food packages
• Weak ice production or ice clumping (often tied to temperature and airflow)
• Water under the refrigerator or inside the fresh food section

Quick checks we recommend before replacing parts

1. Confirm temperatures: Set freezer near 0°F and refrigerator near 37°F (typical targets).
2. Check airflow: Make sure vents inside both compartments are not blocked by food.
3. Clean condenser area: Dust buildup reduces cooling efficiency.
4. Look for frost patterns: Heavy frost points to a defrost problem.
5. Listen for fans: A failed fan can mimic a “bad compressor” symptom.

Common causes and the parts that often relate

Symptom	Common cause	Parts that may be involved (examples)
Not cooling or weak cooling	Sealed-system or compressor issue	Refrigerator compressor TCA38091801, refrigerator filter dryer ADH73590310
Frost buildup, warming temps	Defrost system problem	Refrigerator defrost heater 5300JB1114Z, refrigerator defrost sensor EBD61246710
Ice maker slow or not making ice	Temperature, water supply, or ice maker issue	Refrigerator ice maker AEQ73130002, kenmore elite refrigerator water inlet valve AJU34125567
Water tastes bad or flow is weak	Clogged water filter	LG refrigerator water filter ADQ73613401

Why it matters

Cooling problems can quickly lead to food spoilage and can also trigger secondary issues like ice maker failures and frost buildup. Starting with airflow, temperature settings, and basic maintenance helps you avoid replacing parts that are still good.

If your LG LSXS26326B side-by-side refrigerator is warm in both sections, runs much longer than normal, or makes repeated clicking or buzzing from the back, the compressor can be failing. Confirm basic settings first because Demo Mode, airflow issues, or normal high-efficiency compressor sounds can look similar; use the owner's manual troubleshooting steps.

Quick checks before blaming the compressor

We recommend ruling out common look-alikes first because they can cause “not cooling” symptoms without a sealed-system failure.

• Make sure the temperature controls are not set to OFF.
• Check that the refrigerator is not in Demo Mode (lights and display work but cooling does not).
• Verify both doors close fully and are not being held open by bins or food.
• Listen for normal operating sounds; a pulsating or high-pitched sound can be normal on high-efficiency compressors.
• After unplugging, wait 5 minutes before plugging back in (helps protect the compressor).

Signs that point more strongly to a bad compressor (or sealed-system problem)

These symptoms usually show up together:

• Both the freezer and fresh food sections are warming.
• The unit runs constantly with little or no temperature improvement.
• Repeated clicking (start attempt) followed by silence, then repeating.
• The cabinet may feel unusually warm near the compressor area.
• Little to no frost pattern develops on the evaporator (requires inspection).

What you can safely do at home

What you observe	What it often means	What to do next
Lights/display work but no cooling	Demo Mode or control setting	Recheck settings in the manual
Clicking every few minutes	Start device overload, compressor struggling	Have a technician test the start circuit and compressor
High-pitched/pulsating while running	Normal operation on efficient compressor	Monitor temps for 24 hours
Warm fridge and no ice	Cooling system not removing heat	Check airflow, coils, then sealed system

Parts that may be involved

If a technician confirms a compressor failure on LSXS26326B, the replacement is the refrigerator compressor TCA38091801. Sealed-system repairs can also involve components like the refrigerator filter dryer ADH73590310.

Why it matters

A true compressor or sealed-system issue affects both compartments and can lead to food spoilage quickly. Ruling out settings (OFF/Demo Mode) and normal sound behavior prevents unnecessary parts replacement.
