LG LMXS30776D/04 refrigerator Parts

The LG LMXS30776D has a total capacity of about 29.7 cubic feet. For the exact capacity breakdown and specifications for your specific configuration, we recommend confirming it in the LMXS30776D owner's manual.

Quick specs to confirm in the manual

Capacity is usually listed with other key specs (dimensions, electrical, and installation clearances). In the manual, check for:

• Total capacity (cu. ft.)
• Refrigerator vs. freezer compartment capacity
• Door-in-door or drawer capacity (if applicable)
• Required clearances and door swing space
• Water supply requirements for the ice maker and dispenser

Why capacity matters

Knowing the correct capacity helps when you are comparing models, planning kitchen fit, and setting expectations for storage. It also helps when troubleshooting cooling complaints, since overloading a compartment can restrict airflow and affect temperature stability.

Helpful maintenance tip (often tied to capacity and performance)

If you notice slower water flow or reduced ice production, a clogged filter can be the cause. This model uses the parts assembly,ice water ADQ73613401 water filter, and it is typically replaced about every 6 months or sooner if flow drops.

For the LG LMXS30776D refrigerator, the most common customer-reported issue is a cooling failure (refrigerator or freezer too warm). In many cases, the root cause is in the sealed-system cooling components (such as the compressor), but airflow restrictions, dirty condenser vents, or defrost-related problems can create the same symptoms; use the owner's manual troubleshooting steps first.

What to check first (fast, no-tools checks)

• Confirm the doors fully close and are not being held open by bins or food packages.
• Reduce door-opening time; frequent openings quickly raise temps.
• Make sure air vents inside the compartments are not blocked by food.
• If the unit was recently installed or restarted, allow up to 24 hours to stabilize.
• Clean the condenser cover and vents using a vacuum attachment (do not remove the condenser panel).

Common causes and what they look like

Symptom	Most likely category	What you can do now
Fresh food and freezer both warm	Cooling system or airflow	Check vents, door closure, condenser vent cleaning
Temps swing, some areas warm	Airflow/thermistor/controls	Unblock vents; verify settings; watch for recurring error codes
Clicking/buzzing and not cooling	Compressor start/cooling system	Stop repeated power-cycling; move to deeper diagnosis
Ice/water issues plus warm temps	Water system is separate	Treat as two issues; troubleshoot cooling first

Parts that commonly relate to “not cooling” symptoms

If basic airflow and condenser-vent cleaning do not restore normal temperatures, these model-matched parts are often involved in cooling complaints:

• Refrigerator compressor TCA38091801 (core cooling component)
• Refrigerator evaporator assembly ADL74221802 (heat exchange in the cooling system)
• Refrigerator defrost heater assembly MEE62805303 (helps prevent frost buildup that blocks airflow)
• Refrigerator temperature sensor 6500JB2001B (temperature feedback to the control)

Why it matters

A “too warm” refrigerator can be caused by simple airflow and maintenance issues, but it can also point to a sealed-system problem. Starting with the manual’s troubleshooting steps helps you avoid unnecessary parts replacement and reduces the risk of food spoilage.

For more model-specific operating and troubleshooting guidance, follow the temperature and airflow checks in the owner's manual. If you need to locate additional replacement parts by diagram, you can also search by model number on Sears PartsDirect.

A bottom leak on your LG LMXS30776D refrigerator is usually caused by a clogged or frozen defrost drain, a seeping water supply connection (filter, tubing, or inlet valve), or melted ice overflowing when the ice maker is left off with ice still in the bin. Use the LMXS30776D owner's manual for safety and access guidance.

Most common causes to check

• Defrost drain clogged or iced over: Defrost water can’t reach the drain pan and spills into the base.
• Water filter or filter head leaking: A filter not fully seated or a damaged seal can drip and run down.
• Tubing or fitting seep: A cracked line or loose connection can create a slow puddle.
• Water inlet valve seeping: A valve that doesn’t close fully can feed water intermittently.
• Ice maker off with ice left in the bin: Melted ice can leak; empty the bin if the ice maker is off for more than a few hours.

Quick diagnostic steps (10 to 20 minutes)

• Unplug the refrigerator before inspecting; after unplugging, wait 5 minutes before plugging it back in.
• Pull the unit forward and check the household water line and connections for active drips.
• Inspect the filter area; remove and reinstall the filter firmly and look for cracks or a damaged seal.
• Check the freezer floor under the bottom drawer; ice or water there often points to a defrost drain issue.
• If the ice maker is off, empty the ice bin to prevent overflow from melting cubes.

Parts that often fix water-system leaks

Where you see water	What it often means	Part to consider
Behind unit or under cabinet	Internal line or connection seep	Plastic tube MJU62070602
Filter area	Filter head or filter connection leak	Parts assembly,ice water ADQ73613401
Back lower area near valve	Inlet valve seeping	LG refrigerator water inlet valve AJU72992603

Why it matters

Even small leaks can damage flooring, create odors, and cause ice buildup that restricts airflow and hurts cooling.

For the LG LMXS30776D refrigerator, the limited warranty (USA) provides 1 year parts and labor coverage for the refrigerator/freezer, 5 years parts and labor coverage for the sealed system, and 10 years coverage on the linear/inverter compressor (years 6 to 10 are parts only; labor is charged). Full terms are in the LMXS30776D owner's manual.

Warranty coverage summary (USA)

Refrigerator/freezer	1 year	Parts and labor
Sealed system (condenser, dryer, connecting tube, evaporator)	5 years	Parts and labor
Linear/inverter compressor	10 years	Years 1 to 5 parts and labor; years 6 to 10 parts only

What to confirm for your claim

Warranty eligibility depends on purchase and use details. Before scheduling service, we recommend checking:

• Proof of original retail purchase date (receipt or invoice)
• Whether the issue is sealed-system related (cooling loss, refrigerant system symptoms)
• Whether the repair is compressor-related (labor is typically not included in years 6 to 10)
• That the refrigerator was installed and used under normal conditions
• Any exclusions listed in the warranty section (maintenance items, cosmetic issues, etc.)

Parts that often relate to longer-coverage cooling issues

If you are diagnosing a cooling problem, these model-matched parts are commonly involved:

• Refrigerator compressor TCA38091801 (compressor)
• Drier assembly ADH73590304 (sealed system component)
• Refrigerator evaporator assembly ADL74221802 (sealed system component)

Why it matters

Knowing whether a problem is in the sealed system, compressor, or a non-covered maintenance item helps you estimate out-of-pocket costs and choose the right repair path.
