LG LSC27931SB refrigerator Parts

The LG LSC27931SB is a full-size 36-inch class side-by-side refrigerator. Exact outside dimensions (width, height, depth, and depth with doors/handles) vary by configuration, so we recommend confirming the measurements in the LSC27931SB owner's manual before planning a tight fit.

What to measure (so it fits the first time)

Use a tape measure and record these common refrigerator specs:

• Width: cabinet and widest point (often handles)
• Height: floor to top hinge cover (and with doors open if needed)
• Depth: cabinet only, with doors, and with handles
• Door swing clearance: space needed to fully open both doors
• Ventilation clearance: space behind and above for airflow

Typical size range for 36-inch side-by-side refrigerators

Most 36-inch class side-by-side units fall into these ranges (helpful for planning, then confirm your exact numbers in the manual):

Measurement	Typical range
Width	35 3/4 to 36 inches
Height	68 to 71 inches
Depth (with doors/handles)	33 to 36 inches

Why it matters

Correct sizing prevents installation problems like doors hitting walls, drawers not pulling out fully, and poor airflow that can cause warm temperatures or compressor strain.

Quick fit checklist

Before you move the LG LSC27931SB into place:

• Measure the opening (width, height, depth)
• Measure the refrigerator path (doorways, hallways, turns)
• Confirm door swing space on both sides
• Plan for water line routing to the ice maker and dispenser
• Leave room to remove and replace the water filter such as LG refrigerator water filter lt500p ADQ72910911

On LG model LSC27931SB, CF and E commonly appear together as CFE, which points to a condenser fan error. This usually means the control is not seeing the expected feedback from the condenser fan that cools the condenser coils near the back, bottom of the refrigerator.

What to check first (safe, no-tools steps)

• Unplug the refrigerator for safety before inspecting anything.
• Pull the unit out and confirm there is good airflow behind and underneath.
• Look for dust buildup on the condenser area that can restrict airflow.
• Listen after restart: the condenser fan should run when the compressor is running.
• Check for obstructions (packaging, pet hair, debris) around the fan area.

Likely causes and what they mean

What you notice	Most likely cause	What to do next
Fan is not running, fridge is warm	Failed condenser fan or wiring issue	Inspect fan area; replace the fan if it is seized or noisy
Fan runs sometimes, code returns	Intermittent fan motor, loose connection	Reseat connectors; check for rubbing blades
Fan runs but code persists	Feedback/control issue	Check harness routing; consider control diagnosis

Parts that are commonly involved

If the condenser fan is not operating correctly, these model-matched parts are often part of the fix:

• Refrigerator condenser fan 4681JB1029B (fan blade and motor assembly that moves air across the condenser)
• Refrigerator condenser fan motor damper 5040JA2004A (mounting/support component that can affect fan alignment)

Why it matters

The condenser fan removes heat from the sealed system. When it fails or airflow is blocked, temperatures rise, cooling performance drops, and the refrigerator can run longer than normal.

Model-specific tip

Use the troubleshooting and error-code guidance in the LSC27931SB manual to confirm the exact display behavior (CF alone vs CFE) and the recommended diagnostic steps for your control panel.

The most common LG refrigerator complaint is not cooling properly, which customers often notice as warm fresh food, soft ice, or thawing in the freezer. On the LG LSC27931SB, the most frequent root causes are airflow problems (fan issues), defrost system problems, or water and ice system issues that create leaks or freezing.

What we check first on an LG LSC27931SB that is not cooling

• Confirm the temperature settings: 37°F fresh food and 0°F freezer are typical targets.
• Make sure vents are not blocked by food packages.
• Listen for fan operation (evaporator fan inside, condenser fan near the compressor).
• Check for heavy frost on the rear freezer panel (points to a defrost problem).
• Clean dust from the condenser area and confirm the condenser fan runs.

For model-specific operating details and control locations, use the LSC27931SB owner's manual.

Common symptoms and the most likely causes

Symptom	Most likely cause	What to do next
Freezer cold, fridge warm	Airflow issue (evaporator fan, damper, blocked vents)	Inspect airflow and fan noise; check for frost buildup
Both sections warm	Condenser fan not running, dirty condenser, sealed system or compressor issue	Clean condenser; verify condenser fan operation
Ice maker slow or no ice	Water supply issue, filter restriction, inlet valve issue	Replace filter; verify water pressure
Water leaking	Loose tubing/fitting, inlet valve seep, clogged drain	Inspect fittings and tubing; clear drain path

Parts that commonly affect cooling and water/ice performance

If you are troubleshooting cooling, leaks, or weak water flow on this model, these parts are frequent suspects:

• Refrigerator evaporator fan motor 4681JB1029A (moves cold air through the compartments)
• Refrigerator condenser fan 4681JB1029B (removes heat from the condenser area)
• Refrigerator water filter lt500p ADQ72910911 (a restricted filter can reduce water flow to the dispenser and ice maker)
• Refrigerator water inlet valve assembly 5221JA2006D (controls water flow to the dispenser and ice maker)

Why it matters

When an LG side-by-side starts losing cooling, food safety and compressor workload become immediate concerns. Catching airflow, fan, or defrost issues early often prevents bigger failures and reduces temperature swings.

LG side-by-side refrigerator pricing depends on capacity, finish, and features; for LG model LSC27931SB, the most accurate price comes from comparing current listings for the exact model number and condition (used, refurbished, or new old stock). For model details that affect value, use the LSC27931SB manual.

Typical price ranges (what to compare)

Because LSC27931SB is an older side-by-side refrigerator, availability and condition drive the price more than the original MSRP.

• Used (local pickup): lowest cost; condition varies the most
• Refurbished: mid-range; typically tested and cleaned
• New old stock (rare): highest cost when available
• Finish and cosmetics: dents, rust, and door wear change value quickly
• Ice and water dispenser performance: strongly affects resale value

Condition	What you’re paying for	What to verify before buying
Used	Basic cooling and appearance	Temps, door seals, dispenser output
Refurbished	Serviced unit	What was replaced, warranty terms
New old stock	Unused, limited supply	Return policy, shipping damage coverage

What changes the price the most

These checks help you estimate whether you’re buying a “ready to use” refrigerator or one that needs repairs.

• Fresh food section holds about 37°F and freezer holds about 0°F
• Doors close and seal evenly; no warm air leaks
• Ice maker fills and harvests; dispenser dispenses steadily
• No loud grinding from the fan or compressor area
• Water system is maintained (filter changes and no leaks)

Why it matters

A low purchase price can disappear fast if the refrigerator needs water system repairs. If the dispenser is weak or the ice maker is inconsistent, common fixes include replacing the refrigerator water inlet valve assembly 5221JA2006D or installing the correct water filter for your exact setup.

Water filter note (to avoid buying the wrong part)

For LSC27931SB, confirm the filter type by checking the filter housing label and the LSC27931SB manual before ordering. LG used multiple filter styles across similar side-by-side platforms, so matching by model number and housing style prevents fit and leak issues.
