LG LFX28968ST/01 refrigerator Parts

Most LG refrigerators, including the LG LFX28968ST, commonly last about 10 to 15 years with normal household use. Actual lifespan varies based on installation, cleaning, and how quickly cooling or ice-maker issues are corrected; consistent maintenance can help you reach the upper end of that range. For model-specific care guidance, use the LFX28968ST manual.

What affects lifespan the most

• Condenser cleanliness: Dust buildup makes the sealed system work harder.
• Door seal condition: Leaky gaskets cause longer run times and temperature swings.
• Airflow and loading: Overpacking blocks vents and stresses the evaporator fan.
• Water system upkeep: Old filters can reduce flow and strain the inlet valve.
• Room conditions: Hot garages and tight cabinetry reduce efficiency.

Maintenance checklist (practical, high-impact)

• Vacuum and brush the condenser area every 6 to 12 months.
• Keep doors closing squarely; avoid slamming and check alignment if doors drift.
• Replace the water filter on schedule; use the correct LG kenmore refrigerator water filter ADQ36006101.
• Confirm temperatures stay steady (typical targets: 37°F fresh food, 0°F freezer).
• Address unusual noises, warm spots, or repeated icing early.

Parts that often influence “how long it lasts”

Symptom you notice	Commonly involved area	Example compatible part for this model
Warm refrigerator/freezer, long run times	Sealed system or start components	Refrigerator compressor TCA38091801
Poor water flow or slow ice production	Filtration or water supply	LG kenmore refrigerator water filter ADQ36006101
Lights or alarms act odd when door closes	Door sensing	Refrigerator door switch 6600JB1010A

Why it matters

A refrigerator that runs longer to hold temperature uses more energy and wears key components faster. Simple upkeep (cleaning coils, keeping doors sealed, changing filters) is often the difference between an average lifespan and a longer one.

For the LG LFX28968ST, the most common issue we see customers troubleshooting is cooling problems (refrigerator or freezer not staying cold). The root cause varies by symptom, but it often traces to airflow restrictions, fan/defrost issues, or a compressor-related failure; use the LFX28968ST manual to confirm the correct checks and settings for your exact unit.

What “not cooling” usually looks like

• Fresh food section warm but freezer OK (airflow or damper/duct issue)
• Freezer warm and ice cream soft (sealed system or compressor-related)
• Frost buildup on the back wall (defrost system issue)
• Loud humming or clicking with poor cooling (start device or compressor)
• Temperatures swing after door openings (gasket or door alignment)

Model-relevant parts that commonly relate to cooling complaints

If troubleshooting points to a failed component, these are examples of compatible parts for LFX28968ST that can be involved in cooling performance:

Symptom you notice	Often-related system	Example compatible part for this model
Warm fridge and freezer, compressor struggles to start	Compressor start circuit	Refrigerator compressor start relay EBG60663230
Persistent warm temps, sealed system diagnosis needed	Compressor/sealed system	Refrigerator compressor TCA38091801
Frost buildup, poor airflow	Defrost sensing/control	Refrigerator defrost sensor assembly 6615JB2005N
Weak airflow or warm cabinet with fan noise changes	Air movement across coils	Refrigerator freezer evaporator cover and fan assembly AEB73764547

Quick checks we recommend before replacing parts

• Verify temperature settings and allow 24 hours after any adjustment.
• Make sure vents inside the refrigerator and freezer are not blocked by food packages.
• Check door closure and gasket contact all the way around.
• Clean dust from the condenser area and confirm the condenser fan runs.
• If you have an error code, use LG bottom freezer refrigerator error codes to narrow the failure.

Why it matters

Cooling problems can spoil food quickly and can also cause secondary issues like excessive frost, long run times, and ice maker performance problems. Early troubleshooting helps you avoid replacing the wrong part and helps identify when a sealed system repair requires a technician.

On the LG LFX28968ST, water leaking from the bottom is most often caused by a defrost drain problem (meltwater can’t reach the drain pan), or a leak in the ice maker or water supply system. We use the LFX28968ST manual to identify access points and safe disassembly steps.

Quick checks (start here)

• Confirm the liquid is water (not oily) and note if it’s clear or tinted.
• Check if the puddle appears after defrost cycles (often points to a drain issue).
• Look for ice buildup on the freezer floor or under the crisper drawers.
• Inspect the water filter area and tubing connections for drips.
• Check the ice maker fill area for splashing or overflow.

Most common causes and what to do

1) Clogged or frozen defrost drain

When the drain is blocked, defrost water can overflow into the cabinet and run down to the floor.

• Unplug the refrigerator.
• Remove the freezer drawer/bins as needed.
• Melt any ice around the drain trough with warm air (hair dryer on low) and flush the drain with warm water.

2) Leak in the water supply system (filter, tubing, valve)

A slow drip can travel along lines and show up as a puddle at the front.

• Reseat the filter and check the housing for cracks.
• Inspect the line for kinks or rub-through; replace if damaged using refrigerator water tubing MJU62070602.
• If the leak is at the rear inlet connection or valve body, test/replace LG refrigerator water inlet valve 5221JB2010G.

3) Ice maker leak or overflow

A misaligned fill tube or failing ice maker can drip into the freezer and out the bottom.

• Look for ice stalactites near the ice maker fill area.
• If the ice maker is leaking or not cycling correctly, replace refrigerator ice maker assembly AEQ72910411.

Symptom-to-cause guide

What you notice	Most likely cause	Best next step
Ice on freezer floor, water after defrost	Defrost drain clogged/frozen	Thaw and flush drain
Puddle near front, no ice buildup	Water line/filter leak	Inspect filter, tubing, valve
Water near ice bin or ice clumps	Ice maker leak/overfill	Inspect fill area, replace ice maker

Why it matters

Bottom leaks can damage flooring and can also lead to hidden ice buildup that restricts airflow, causing warm temperatures and poor ice production.

On the LG LFX28968ST bottom-mount refrigerator, freezer frost is usually caused by warm, moist air leaking past the door seal or by defrost water not draining and refreezing on the freezer floor. Start by checking the door seal and looking for ice on the bottom.

Quick checks we recommend

• Confirm the freezer drawer closes fully and isn’t blocked by food packages.
• Inspect and clean the door gaskets; residue can prevent a tight seal.
• Look for a sheet of ice on the freezer floor (often points to a drain issue).
• Make sure interior vents are not blocked, which can worsen frost.
• Verify temperatures are set appropriately (freezer near 0°F, fresh food near 37°F).

Most common causes and fixes

Door air leak

If the gasket is torn, warped, or not sealing, humid kitchen air enters and freezes.

• Clean the gasket and cabinet sealing surface with mild soap and water.
• Do a paper test: close the door on paper; it should resist being pulled out.
• Replace a damaged gasket if it won’t seal.

Model-matched gasket options:

• Refrigerator door gasket, left ADX73550621
• Refrigerator door gasket, right ADX73550624

Iced or blocked defrost drain

If defrost water can’t drain, it refreezes and can create ice on the freezer floor, leading to recurring frost.

• Unplug the refrigerator.
• Melt and remove ice (hair dryer on low, keep heat moving).
• Flush the drain with warm water until it flows freely.

Symptoms guide

What you see	Most likely cause	What to do next
Frost around door edges	Door not sealing	Clean/inspect gasket, check closure
Sheet of ice on freezer floor	Drain iced/blocked	Thaw and flush drain
Frost returns quickly after defrost	Possible defrost control issue	Inspect for heavy frost behind rear panel

Why it matters

Frost restricts airflow across the evaporator, which can cause warmer freezer temperatures, longer run times, and water leaks when ice melts.
