LG LFCS25426D/00 bottom-mount refrigerator Parts

For your LG LFCS25426D bottom-mount refrigerator, the most reliable way to identify the correct water filter is to match the filter part number listed for your exact model in the owner's manual. This prevents fit issues, leaks, and poor-tasting water caused by using the wrong cartridge.

Fast ways to identify the right filter

• Check the filter label on the current cartridge (the part number is usually printed on the end cap).
• Look up the filter part number by model (LFCS25426D) in the owner's manual.
• Inspect the filter housing location (fresh food compartment, ceiling, upper right, etc.) and compare the cartridge shape to your current one.
• If the filter was removed, check your purchase history or the old packaging for the part number.
• If your refrigerator has a filter indicator light, plan to reset it after replacement (steps are typically in the manual).

What you should match (so it fits and seals)

What to match	Why it matters	Where to find it
Model number: LFCS25426D	Ensures the correct filter family	Rating label inside the refrigerator
Filter part number	Prevents leaks and bypassing	Filter label or owner's manual
Cartridge style (twist-in, push-in)	Avoids broken housings and poor sealing	Visual check of the old filter
Change interval (typical 6 months)	Maintains flow and taste	Manual and your water quality

Why it matters

Using the correct LG filter for LFCS25426D helps maintain proper water flow to the dispenser and ice maker, keeps filtration performance consistent, and reduces the chance of O-ring leaks or a filter that will not lock into the housing.

Ordering tip

Once you have the filter part number, order the exact replacement listed for your model from the parts list for LFCS25426D, or search by model number on Sears PartsDirect.

In most refrigerators (including the LG LFCS25426D bottom-mount), the most commonly replaced parts are the ones that affect sealing, airflow, and everyday usability: door gaskets, fan-related cooling parts, and storage components such as bins and drawers. For model-specific diagrams and part locations, use the owner's manual.

Most commonly replaced refrigerator parts

These are the parts we see replaced most often across bottom-mount and French door refrigerators:

• Door gaskets (seals): stop warm air leaks that cause sweating, frost, and long run times
• Airflow and cooling parts: evaporator fan-related components, air ducts, and evaporator assemblies
• Ice and water system parts: water filter, water inlet valve, ice maker components, dispenser tubing
• Sensors and controls: thermistors (temperature sensors) and electronic control boards
• Wear-and-tear hardware: hinges, door stops, springs, and handle hardware
• Storage parts: door bins, crisper drawers, deli drawers, freezer drawers

Common replacements we stock for LG LFCS25426D

These are examples of frequently ordered parts for this model when a bin cracks, a drawer breaks, or a seal starts leaking:

• Refrigerator door bin AAP73871501
• LG refrigerator deli drawer AJP73874601
• Refrigerator door gasket, left ADX73550628
• Kenmore refrigerator door gasket, right ADX73550627

Quick symptom-to-part guide

Symptom	Most likely part area	What to check first
Condensation or frost near doors	Door gasket, door alignment	Look for gaps, torn corners, or a door that sits low
Warm fridge but freezer OK	Airflow in fresh food section	Blocked vents, iced-up evaporator area, fan noise changes
Noisy clicking or hard starting	Compressor start components	Listen for repeated clicking, check for overheating at rear
Broken storage or poor fit	Bins, drawers, rails	Cracks, missing tabs, warped plastic

Why it matters

A small air leak or airflow restriction can make the compressor run longer, raise temperatures, and increase energy use. Replacing a gasket, bin, or drawer early often prevents bigger cooling complaints later.

For step-by-step part identification and access panels, we recommend matching your symptom to the exploded-view diagrams in the owner's manual.

For LG refrigerators like model LFCS25426D, the most common service issue we see is a cooling failure. That can be caused by a sealed-system/compressor problem, but it is also commonly tied to airflow issues (dirty condenser coils, a fan problem, or frost buildup from a defrost issue). See the LFCS25426D owner's manual for the normal temperature settings and operating checks.

What you will usually notice first

• Fresh food section warming up while the freezer seems “okay” at first
• Clicking, humming, or buzzing sounds near the back or bottom
• Frost buildup on the rear freezer panel (restricted airflow)
• Longer run times and temperature swings
• Ice maker slowing down or stopping because the freezer is too warm

Quick checks that solve many “not cooling” calls

1. Confirm settings: Refrigerator about 37°F and freezer about 0°F (typical targets).
2. Clean condenser coils: Dusty coils make the compressor work harder and reduce cooling.
3. Check door sealing: A leaking gasket lets in warm, moist air that drives frost and poor cooling.
4. Listen for fans: You should typically hear airflow when the unit is running.
5. Avoid blocked vents: Do not pack food tightly against air returns.

Parts that commonly relate to cooling symptoms on LFCS25426D

If basic checks do not restore cooling, these model-specific parts are often involved in diagnosis and repair:

Symptom	Common area	Example part on this model
Warm temps, loud running, won’t maintain cooling	Sealed system	Refrigerator compressor TCA38091801
Poor cooling after moving or vibration, rattles near compressor	Compressor mounting	Refrigerator compressor mount retainer clip 4620JA3015A
Frost pattern issues, weak airflow, warm fridge section	Evaporator area	Refrigerator evaporator assembly ADL73741411

Why it matters

Cooling problems can snowball fast: warmer temperatures increase moisture, moisture creates frost, and frost blocks airflow. Catching the issue early helps protect food, reduces energy use, and can prevent secondary damage to fans, ducts, and door seals.

Yes. On the LG LFCS25426D bottom-mount refrigerator, we see many customers successfully replace non-electrical parts like door bins, drawers, and door gaskets with basic hand tools and careful handling. For sealed-system or high-voltage repairs (such as compressor work), we recommend using a qualified technician and using the LFCS25426D owner's manual for model-specific guidance.

Good DIY replacements for this model

These are typically straightforward because they involve removing screws, clips, or sliding parts in and out:

• Door storage: refrigerator door bin AAP73871501 or refrigerator door bin AAP73871601
• Drawer components: LG refrigerator deli drawer AJP73874601
• Door sealing parts: refrigerator door gasket, left ADX73550628 and kenmore refrigerator door gasket, right ADX73550627
• Door swing hardware: refrigerator door stop 4620JJ2009A

Repairs to leave to a technician

These repairs can involve refrigerant handling, specialized tools, or electrical diagnosis:

• Sealed-system work (refrigerant lines, leaks)
• Compressor replacement: refrigerator compressor TCA38091801
• Evaporator system repairs: refrigerator evaporator assembly ADL73741411
• Control/display diagnosis (wiring and boards)

Quick decision guide

Repair type	Typical DIY difficulty	Why
Door bin or drawer replacement	Easy	Mostly slide-in or a few fasteners
Door gasket replacement	Medium	Requires careful alignment for a tight seal
Door stop or hinge-related parts	Medium	Door alignment matters for sealing
Compressor or evaporator replacement	Hard	Sealed-system and electrical complexity

Why it matters

Choosing the right DIY repair protects food temperatures and energy use. A misaligned gasket or door hardware can cause warm spots, frost buildup, and longer run times, while sealed-system mistakes can turn a repair into a much bigger problem.

A bottom leak on your LG LFCS25426D bottom-mount refrigerator usually happens when water cannot drain correctly or when the ice and water system drips. The most common causes are a clogged defrost drain, a water line or ice maker leak, or a door gasket that lets in humid air.

Quick checks we recommend first

• Look for water or a thin ice sheet under the crisper drawers; this often points to a defrost drain clog.
• Check the ice container area for wet clumps of ice or dripping; this often points to an ice maker fill or supply leak.
• Inspect both door gaskets for gaps, rips, or sections that do not sit flat.
• Make sure the refrigerator is level; poor leveling can cause water to miss the drain pan.
• Check that the drain pan is seated correctly and not cracked.

Most common causes and what to do

Likely cause	What you will notice	What usually fixes it
Clogged defrost drain	Water pooling inside, then leaking out the bottom	Melt ice, flush the drain with hot water, clear debris
Ice maker or water supply leak	Leak near freezer/ice area; wet ice clumps	Tighten fittings, replace damaged tubing, correct fill alignment
Door gasket not sealing	Condensation, frost, or water trails near door edges	Clean gasket, warm and reshape, replace if torn
Drain pan issue	Water only under unit; pan out of place	Reseat pan; replace if cracked

Door gasket fixes (common on bottom leaks)

If the gasket is torn or permanently warped, replace it:

• Right side: kenmore refrigerator door gasket, right ADX73550627
• Left side: refrigerator door gasket, left ADX73550628

For sealing and alignment tips, use how to fix a fridge door seal.

Why it matters

Stopping the leak prevents floor damage and odors, and it helps avoid frost buildup that can reduce airflow and cooling efficiency.

Model-specific guidance

Use your LFCS25426D owner's manual for leveling instructions, drain pan location, and routine cleaning steps.
