What is the problem with the LG bottom freezer refrigerator?
On the LG LFXS26973S bottom-mount refrigerator, the most common “problem” we see is uneven cooling: the refrigerator section warms up while the freezer stays cold. On this model, that typically points to airflow restriction, a fan or sensor issue, or the unit being in Display (Demo) Mode. See the LFXS26973S owner's manual for model-specific troubleshooting.
Quick checks we recommend first (no tools)
- Look at the control panel for OFF; that indicates Display Mode and cooling is disabled.
- Reset to the factory defaults: 37°F (refrigerator) and 0°F (freezer).
- Make sure interior air vents are not blocked by food packages.
- Confirm both doors close fully and seal all the way around.
- After any setting change, allow up to 24 hours for temperatures to stabilize.
Common causes and what to check next
| Likely cause | What you’ll notice | What to do next |
|---|---|---|
| Display (Demo) Mode | Controls work but no cooling | Turn Display Mode off per the manual |
| Airflow blockage | Warm fridge, cold freezer | Clear vents, avoid overpacking |
| Evaporator fan not moving air | Weak airflow, temp swings | Diagnose the refrigerator evaporator fan motor EAU63923603 |
| Temperature sensing problem | Temps drift, inconsistent readings | Test the refrigerator temperature sensor 6500JB2002E |
Why it matters
Uneven cooling can spoil food in the fresh food section even when the freezer seems normal. Fixing airflow, fan, or sensor problems early also helps reduce compressor run time and energy use.

What part number is the LG LFXS26973S water filter?
For the LG LFXS26973S refrigerator, the compatible water filter is the LT1000P-style cartridge; on our parts list it’s shown as LG lt1000p refrigerator water filter ADQ74793501. For replacement steps and flushing, follow the LFXS26973S owner's manual.
How to confirm you have the right filter
Use these quick checks before ordering:
- Match the model number on your rating label to LFXS26973S.
- Confirm your filter is the twist-in style located inside the fresh food compartment.
- Look for “LT1000P” compatibility on the filter packaging.
- Replace about every 6 months, or sooner if water flow slows.
Replacement notes for LFXS26973S
The manual for this model family specifies these key points:
- Turn the old filter counterclockwise to remove.
- Install the new filter and turn clockwise until it stops.
- Flush about 2.5 gallons after replacement (use 30 seconds on, 60 seconds off cycles).
- Reset the filter indicator by pressing and holding the Water Filter button for 3 seconds.
Quick reference table
| Item | What to use | Typical interval |
|---|---|---|
| Water filter cartridge | LT1000P-compatible (example: ADQ74793501) | Every 6 months |
| Flush after install | 2.5 gallons total | After each filter change |
| Indicator reset | Hold Water Filter button 3 seconds | After each filter change |
Why it matters
Using the correct water filter for LFXS26973S helps maintain water taste, protects dispenser flow, and supports normal ice maker performance by reducing restriction as the filter loads up.

What is the average lifespan of LFXS26973S?
The average lifespan of the LG LFXS26973S bottom-mount refrigerator is 13 years. You can often extend service life by keeping airflow clear, maintaining door seals, and staying on schedule with filter changes listed in the owner's manual.
What affects lifespan most
- Condenser cleanliness and airflow (dust buildup makes the compressor work harder)
- Door seal condition (warm air leaks increase run time and frost)
- Ice maker and water system maintenance (clogs and leaks create secondary damage)
- Stable temperatures (fresh food near 37°F, freezer near 0°F)
- Power quality (surges and repeated outages shorten control and compressor life)
Maintenance schedule we recommend
| Task | Typical interval | Helps prevent |
|---|---|---|
| Replace air filter | Every 6 months | Odors, stale air circulation |
| Replace water filter | Every 6 months | Slow dispensing, poor ice quality |
| Vacuum condenser area | Every 6 to 12 months | Overheating, loud running |
| Inspect/clean door gaskets | Every 3 months | Frost, temperature swings |
If you need parts for routine upkeep, common items for this model include the LG lt1000p refrigerator water filter ADQ74793501 and the LG refrigerator air filter ADQ73214408.
Why it matters
A refrigerator that runs longer and hotter than normal wears out the compressor and fans faster. Simple maintenance reduces run time, stabilizes temperatures, and helps protect major components like the compressor and control board.
