What air filter does my LG refrigerator use?
For an LG LFX28968ST refrigerator, the correct air filter is the one specified for your exact model and filter housing; the most common LG choice is the LT120F (ADQ73214404), but we recommend matching by the part number printed on your current filter or confirming in the LFX28968ST owner's manual.
How to identify the right air filter (fast checks)
- Open the air filter cover inside the fresh food compartment and remove the existing filter.
- Look for a printed part number on the filter frame (this is the most reliable match).
- Compare the filter’s shape (often a small square cartridge) and how it locks into the cover.
- If the cover is missing or damaged, replace the cover first so the new filter seals correctly.
- After installing the new filter, reset the air filter indicator (if your model has one).
Common LG air filter options (what you’ll typically see)
These are common across many LG French door and bottom-mount refrigerators; your LFX28968ST should match one of these styles.
| Filter family | Typical replacement interval | What it helps with |
|---|---|---|
| LT120F style (often labeled ADQ73214404) | About every 6 months | Odors and stale air in the fresh food section |
| Other LG air filter styles | About every 6 months | Same purpose; different fit and cover design |
Why it matters
A correctly fitting refrigerator air filter keeps airflow clean through the deodorizing system, which helps reduce food odors and keeps the fresh food compartment smelling normal. Using the wrong filter (or a damaged cover) can cause poor sealing and weak odor control.

What size is LFX28968ST?
The LG LFX28968ST is a 36-inch class bottom-mount (French door) refrigerator. For the exact exterior dimensions (width, height, depth with and without handles) and the listed capacity for your specific unit, we recommend confirming the specifications in the LFX28968ST owner's manual.
What “size” usually means for this model
When customers ask about refrigerator size, it typically refers to one or more of these specs:
- Width class (commonly 36-inch for this model family)
- Total capacity (cubic feet)
- Overall height (floor to top of hinge)
- Depth (with handles, without handles, and depth with door open)
- Cutout/clearance needs (space for airflow and door swing)
Quick spec checklist to measure at home
Use a tape measure and record these numbers before ordering parts or planning a move:
- Width at the widest point (often the doors)
- Height to the top hinge cover
- Depth to the front of the doors (and to the handle ends)
- Clearance behind the unit for the water line and airflow
- Door swing space (especially for French doors)
Typical “36-inch class” refrigerator dimensions (reference)
These are common ranges for 36-inch French door refrigerators; use them as planning guidance and confirm your exact numbers in the manual.
| Measurement | Typical range (36-inch class) | Why you care |
|---|---|---|
| Width | 35 3/4 to 36 in | Fit through doorways and into the cabinet opening |
| Height | 68 to 71 in | Overhead cabinet clearance |
| Depth (with handles) | 34 to 37 in | Counter projection and walkway space |
| Depth (without handles) | 32 to 35 in | Tighter installs |
Why it matters
Correct size details prevent installation headaches and help you avoid issues like doors not opening fully, poor airflow that hurts cooling performance, or kinks in the water line that can affect the ice maker and dispenser.

What is the most common problem with an LG refrigerator?
The most common problem we see with LG refrigerators like model LFX28968ST is a cooling problem (refrigerator or freezer not staying cold). The most frequent root causes are airflow restrictions (frost buildup or blocked vents), a failing compressor system, or a control/defrost issue; the LFX28968ST owner's manual helps you confirm settings and basic checks.
Most common symptoms (what you’ll notice)
- Fresh food section warms up while the freezer seems “okay” (or vice versa)
- Temperatures swing, food spoils faster, or ice cream gets soft
- Louder-than-normal humming, clicking, or buzzing during cooling cycles
- Frost buildup on the freezer back wall (airflow gets choked off)
- Ice maker slows down or stops because the freezer is not cold enough
Quick checks we recommend first
- Confirm temperature settings and allow 24 hours after changes.
- Check door sealing: look for gaps, rips, or corners that do not sit flat.
- Clear airflow: do not block interior vents with food packages.
- Clean condenser area (dust buildup raises temps and run time).
- If you have an ice maker issue too, verify the freezer is reaching proper temps before replacing parts.
Parts that commonly relate to cooling complaints
| Symptom | Common area to inspect | Example part for LFX28968ST |
|---|---|---|
| No cooling or weak cooling | Sealed system/compressor start components | Refrigerator compressor start relay EBG60663230 |
| Warm temps, long run time | Condenser airflow/heat rejection | Refrigerator condenser coil ACG73784701 |
| Ice maker not making ice (often tied to warm freezer) | Ice maker and freezer temp | LG refrigerator ice maker AEQ73110210 |
Why it matters
Cooling problems are the “root” complaint because they can trigger secondary issues like poor ice production, excess frost, and higher energy use. Catching airflow and sealing problems early can prevent bigger failures and reduce food loss.

What is the average lifespan of an LG fridge?
Most LG refrigerators, including the LG LFX28968ST, typically last 10 to 15 years with normal household use. Consistent maintenance (cleaning coils, keeping door seals tight, and changing filters on schedule) is what most often determines whether you land closer to 10 years or closer to 15.
Typical lifespan ranges (what to expect)
- Average: 10 to 15 years
- Often achievable with good care: 15+ years
- Most common life-limiting issues: cooling system wear, airflow problems, and water/ice system leaks
| Component | Typical impact on lifespan | What you can do |
|---|---|---|
| Compressor | Biggest factor in long-term cooling | Keep condenser area clean and well ventilated |
| Door gaskets | Affects temperature stability and run time | Inspect for gaps, clean, and replace if torn |
| Ice maker and water system | Can cause leaks or poor ice production | Replace filters, purge air, fix slow fills early |
| Control board and sensors | Can cause erratic temps or no-cool | Address error codes and temperature swings promptly |
Maintenance that helps your LG fridge last longer
- Vacuum dust from the condenser area regularly (more often with pets).
- Keep doors closing tightly; replace worn seals such as the refrigerator door gasket, left ADX73550621 or refrigerator door gasket, right ADX73550624 if you feel warm air leaks.
- Change the water filter on schedule; follow how to replace the water filter in an LG refrigerator.
- Avoid overpacking; good airflow helps the evaporator fan and air ducts cool evenly.
- Keep temperatures steady (about 37°F fresh food, 0°F freezer) to reduce compressor run time.
Why it matters
A refrigerator that runs longer to hold temperature uses more energy and puts extra wear on key parts like the compressor, condenser coil, and fans. Simple upkeep helps prevent “runs all the time,” warm spots, and premature part failures.
When it may be time to repair vs. replace
| Symptom | More likely a repair | More likely end-of-life |
|---|---|---|
| Warm fridge/freezer but fans run | Door gasket, airflow, defrost issue | Sealed system/compressor issue |
| Loud clicking then no cooling | Start relay or control issue | Compressor not starting repeatedly |
| Slow ice or no ice | Ice maker or inlet valve | Multiple cooling issues plus age |

Can you wash the air filter for an LG refrigerator?
For LG model LFX28968ST, we do not recommend washing the refrigerator air filter with water. Most LG fresh air filters are carbon filters designed to be replaced on a schedule (commonly about every 6 months) rather than cleaned; follow the steps in the LFX28968ST owner's manual for your exact filter type and reset procedure.
What to do instead (recommended)
- Replace the air filter when the indicator light comes on or on a routine schedule.
- If your model uses a reusable style filter, remove it and dry it only (no rinsing).
- Reset the air filter indicator after service so the reminder stays accurate.
- Keep the doors closed as much as possible while servicing the filter.
- If odors persist after filter service, clean spills and check for spoiled food.
Quick guidance: washable vs. replaceable
| Filter type | Can you wash it with water? | What works best |
|---|---|---|
| Carbon “fresh air” filter (most common) | No | Replace the filter, then reset the indicator |
| Reusable style (less common) | No | Dry thoroughly (air-dry, sunlight, or gentle warm air), then reinstall |
Why it matters
Washing a carbon air filter can saturate the media and reduce odor absorption, which can leave your LG refrigerator smelling stale even though airflow seems normal. Proper replacement or dry-only maintenance keeps food odors under control and helps the filter reminder stay meaningful.

Recommended replacement schedule
- Typical home use: every 6 months
- Heavy odor load (fish, onions, strong cheeses): every 3 to 4 months
- High humidity or frequent door opening: every 4 to 6 months
- After a power outage or odor event: replace early if smells persist after cleaning
Quick signs it is time to change the air filter
- Odors return soon after cleaning the refrigerator
- Food absorbs smells more easily than usual
- The air filter indicator (if equipped) shows it is time
- You recently deep-cleaned and want a fresh baseline
What to do when you replace it
- Install the new filter per the LFX28968ST owner's manual.
- Reset the filter indicator (if your model uses one).
- Wipe spills and clean door gaskets so odors do not immediately come back.
Air filter vs water filter (common mix-up)
| Filter type | What it helps with | Typical interval |
|---|---|---|
| Refrigerator air filter | Odors and air freshness inside the fresh food compartment | About 6 months |
| Refrigerator water filter | Taste/odor in drinking water and ice, flow rate | Often 6 months (varies by use and water quality) |
If you are changing the water filter too, use our guide: how to replace the water filter in an LG refrigerator.
Why it matters
A saturated air filter cannot absorb odors effectively, so smells linger and can transfer to uncovered foods. Replacing it on schedule is a simple maintenance step that helps your LG bottom-mount refrigerator stay cleaner-smelling with less effort.
