LG LFX28968ST/03 refrigerator Parts

Most LG refrigerators last 10 to 15 years with normal household use. For the LG LFX28968ST, lifespan depends most on compressor health, door seal condition, and routine cleaning; consistent maintenance helps you reach the upper end of that range (or longer). See the LFX28968ST owner's manual for model-specific care and cleaning guidance.

What affects lifespan the most

• Condenser cleanliness: dusty coils make the compressor work harder.
• Door seal condition: air leaks force longer run times and can cause frost and temperature swings.
• Temperature settings: keep the fresh food section around 37°F and freezer around 0°F.
• Airflow and loading: avoid blocking vents; do not overpack shelves.
• Water and ice system upkeep: replace filters on schedule and keep the ice bin area clear.

Maintenance checklist (best ROI)

• Vacuum and brush the condenser area every 6 to 12 months.
• Inspect and clean the door gaskets; replace if torn or not sealing (example: refrigerator door gasket, left ADX73550621).
• Keep doors closed as much as possible; confirm doors self-close and align.
• Change the water filter on time; flush the dispenser after changes.
• Listen for new noises (clicking, repeated start attempts, loud humming) that can point to a start or compressor issue.

Common “end-of-life” symptoms and likely causes

Symptom	What it often points to	What we check first
Warm fridge/freezer	Sealed system or airflow problem	Coils, fans, frost buildup
Clicking, won’t start cooling	Start device issue	Refrigerator compressor start relay EBG60663230
Runs constantly	Dirty coils or air leak	Coils, gasket seal
No ice	Ice maker or water supply issue	Fill tube, valve, ice maker

Why it matters

A refrigerator that runs longer and hotter than normal wears the compressor faster and raises energy use. Simple steps like coil cleaning and fixing a weak door seal often add years of reliable cooling.

For LG refrigerators like model LFX28968ST, the most common service issue we see is cooling problems. In many cases, the root cause is in the sealed cooling system (often involving the compressor), but ice maker and water system problems are also frequent.

Most common issues we see (and what they look like)

• Not cooling or warm temperatures in the fresh food section or freezer
• Clicking, buzzing, or humming followed by poor cooling (often points to compressor start or compressor issues)
• Ice maker not making ice or slow ice production
• Water leaks or puddles under or inside the refrigerator
• Frost buildup and temperature swings caused by defrost or airflow problems

Quick checks before replacing parts

1. Confirm the controls are set correctly and the doors close fully; see the LFX28968ST manual.
2. Make sure vents inside the refrigerator are not blocked by food packages.
3. Clean dust from the condenser area (restricted airflow can reduce cooling).
4. If the unit is warm, listen for the compressor and fans running.
5. If you have water or ice issues, verify the household water supply valve is fully open.

Common parts tied to these symptoms

Symptom	Likely system	Example part for LFX28968ST
Not cooling, loud running, or no cooling	Sealed system / compressor circuit	Refrigerator compressor TCA38091801
Clicking and won’t start cooling	Compressor start circuit	Refrigerator compressor start relay EBG60663230
No ice or poor ice production	Ice maker assembly	LG refrigerator ice maker AEQ73110210
Water dispenser slow or no water	Water supply / valve / filter path	LG refrigerator water inlet valve 5221JB2010G

Why it matters

Cooling problems can lead to food spoilage quickly, and water or ice issues can create leaks that damage flooring. Catching symptoms early helps you decide whether a simple maintenance step, a control adjustment, or a targeted part replacement is the right next move.

For LG model LFX28968ST, leaking from the bottom is most often caused by a clogged or frozen defrost drain, which lets defrost water overflow and run down into the fresh food section or out near the base. Use the steps below to clear the drain and stop the leak.

Quick checks that usually solve it

• Unplug the refrigerator before removing panels or using water near wiring.
• Look for a sheet of ice or standing water under the crisper drawers; this points to a defrost drain issue.
• Check the drain pan underneath; if it is cracked or out of position, water can spill at the bottom.
• Inspect door gaskets for gaps that cause excess frost and more defrost water.
• Make sure the refrigerator is level; a forward tilt can encourage water to run out the front.

How to clear a clogged or frozen defrost drain

1. Empty the lower shelves and remove the crisper drawers.
2. Remove the interior rear panel (inside the refrigerator compartment) to access the drain trough.
3. Melt any ice in the trough using warm water (not boiling) and towels.
4. Flush the drain hole with warm water until it flows freely to the drain pan.
5. Clear debris with a flexible pipe cleaner or small zip tie (do not puncture tubing).

If the leak returns quickly, check for heavy frost buildup that indicates an airflow or door-seal problem.

Parts that can be involved

Symptom	Most likely area	What to do next
Water under crispers	Defrost drain frozen/clogged	Clear and flush drain; verify airflow
Water at front corners	Door seal not sealing	Inspect and reshape gasket; replace if torn
Puddle near back/bottom	Drain pan shifted or cracked	Re-seat pan; inspect for damage

If you find a torn or hardened gasket, replacing it restores the seal and reduces frost. For this model, common options include the refrigerator door gasket, left ADX73550621 or refrigerator door gasket, right ADX73550624.

Why it matters

A blocked defrost drain can keep returning water to the bottom of the refrigerator, create ice buildup, and lead to odors or food spoilage. Fixing the drain and door seal helps the defrost system work normally and keeps water directed to the drain pan.
