What is the lifespan of an LG refrigerator?
Most LG refrigerators, including the LG LFX28968ST, typically last 10 to 15 years with normal household use. Lifespan depends most on compressor health, clean airflow (condenser coils), stable temperatures, and routine filter maintenance; our LFX28968ST owner’s manual covers key care steps that help maximize service life.
- Condenser coil cleanliness (dust buildup makes the compressor work harder)
- Door seal condition (warm air leaks increase run time and frost)
- Ventilation and room temperature (tight clearances and hot rooms reduce efficiency)
- Water and air filter maintenance (helps protect the dispenser system and reduce odors)
- How often doors are opened and how full the compartments are
| Task | What to do | Typical frequency |
|---|---|---|
| Replace water filter | Change the filter and reset the indicator | About every 6 months |
| Replace fresh air filter | Swap the air filter to keep odors down | As needed (often every 6 months) |
| Clean condenser area | Vacuum dust from the coil and surrounding area | Every 6 to 12 months |
| Check door gaskets | Inspect for gaps, tears, or hardening | Every 6 months |
If you need compatible replacement filters for this model, use the exact parts listed for LG LFX28968ST, such as the LG kenmore refrigerator water filter ADQ36006101 and the LG refrigerator air filter ADQ73214408.
A refrigerator can run for years past the 10-year mark, but poor airflow, dirty coils, and leaking door gaskets can shorten compressor life and increase energy use. Simple upkeep is often the difference between replacing a major component and getting several more years of reliable cooling.

Why is my LG refrigerator leaking from the bottom?
On the LG LFX28968ST, a leak that shows up at the bottom is most often caused by defrost water not draining correctly (it overflows and runs down into the base area). Less commonly, the leak comes from the ice maker or water supply system, or from a drain tube that is loose or restricted. See the LFX28968ST manual for safety and access guidance.
- Look for water under the crisper drawers (fresh food section); this often points to a defrost drain issue.
- Check for ice buildup on the freezer floor or back panel; that can indicate a drain freeze-up.
- Inspect the water line connection and shutoff valve behind the refrigerator for slow drips.
- Check the ice maker area for overflow, a cracked fill tube, or a mis-seated ice bin.
- Confirm doors close and seal fully; warm air intrusion can increase frost and defrost water.
During defrost, water should flow through the drain to the drain pan. If the drain is clogged or frozen, water can back up and leak out at the bottom.
What to do (safe DIY steps):
- Unplug the refrigerator.
- Remove food and drawers as needed to look for standing water.
- Melt any visible ice with warm (not boiling) water and towels.
- Flush the drain opening with warm water until it flows freely.
- If the drain tube is restricted or damaged, inspect or replace the refrigerator drain tube 5251JA3003D.
If the puddle appears after using ice or water, focus on the water supply path.
| Symptom | Likely area | What we check |
|---|---|---|
| Leak only when dispensing water | Water inlet valve or tubing | Loose fittings, cracked line |
| Ice clumps, dripping at dispenser | Ice chute area | Frost buildup, door not sealing |
| Water in/under freezer drawer | Ice maker fill or drain path | Fill tube alignment, drain blockage |

Bottom leaks can lead to floor damage and can also signal airflow or defrost problems that may worsen cooling performance if left uncorrected.

What is the most common problem with an LG refrigerator?
For LG bottom-mount refrigerators like model LFX28968ST, the most common problem we see is cooling trouble (temperatures rising in the refrigerator and/or freezer). On this model, that typically traces back to airflow restrictions, a fan issue, or a compressor-related cooling system problem.
Start with the operating and troubleshooting guidance in the LFX28968ST owner’s manual. Then do these quick checks before replacing parts:
- Make sure the unit is not in Display Mode (cooling turned off).
- Confirm both doors and the freezer drawer close fully and seal tightly.
- Verify temperature settings are reasonable (typical targets are 37°F fresh food, 0°F freezer).
- Clean dust from the condenser area and keep clearance behind the cabinet.
- Listen for fan operation and check that vents are not blocked by food packages.
| Symptom | Most likely category | What it often indicates |
|---|---|---|
| Fridge warm and freezer warm | Cooling system | Compressor, control, or sealed-system issue |
| Freezer cold but fridge warm | Airflow/defrost | Air not moving to fresh food, frost blocking airflow |
| Clicking or repeated start attempts | Start/cooling components | Overload protector, capacitor, compressor |
| Ice maker or dispenser weak | Water/ice system | Filter restriction, valve issue, ice maker issue |
If the basic checks do not help and you are diagnosing a cooling failure on LFX28968ST, these model-matched parts are commonly involved:
- Refrigerator compressor TCA38091801 (primary cooling component)
- Refrigerator compressor overload protector 6750CL0001D (protects compressor during start/overload)
- Refrigerator run capacitor EAE32501017 (helps the compressor start and run)
- Refrigerator freezer evaporator fan motor EAU63103208 (circulates cold air through compartments)
Cooling problems can lead to food spoilage quickly and can also trigger secondary issues like frost buildup, water leaks from defrost drain overflow, and poor ice production. Catching airflow and fan problems early often prevents bigger repairs.
