LG LSXS22423B/00 refrigerator Parts

On an LG LSXS22423B refrigerator, “FF” and “E” on the display point to a freezer fan error (often shown as “E FF”). It means the freezer evaporator fan is not running correctly, usually because of ice buildup, a blocked fan blade, or a failed fan motor.

What to check first (quick, safe steps)

• Power reset: Unplug the refrigerator (or turn off the breaker) for 5 minutes, then restore power.
• Listen for the fan: After the unit runs a bit, you should normally hear airflow from the freezer area.
• Check for ice blockage: Heavy frost or ice in the freezer rear panel area can stop the fan.
• Confirm vents are clear: Do not pack food tightly against air vents; blocked vents reduce airflow.
• Verify doors seal and close: A door left ajar can cause frost buildup that leads to fan issues.

Likely causes and the most common fixes

What’s happening	What it usually means	Typical fix
Fan is noisy, then stops	Fan blade hitting ice	Defrost and clear ice; improve door sealing
No airflow in freezer	Fan not spinning	Inspect fan area; replace fan motor if failed
Frost builds up quickly	Moist air entering or defrost issue	Check door closure, gaskets, and airflow

Parts that commonly relate to this error

If the fan motor has failed, the freezer side evaporator fan motor is a common repair part for this model: refrigerator freezer evaporator fan motor EAU62064602.

Why it matters

That freezer evaporator fan moves cold air through the freezer and helps circulate air to the fresh food section. When it stops, temperatures rise, food can thaw, and the refrigerator may run longer than normal.

Where to find model-specific guidance

We recommend following the troubleshooting and access steps in the owner's manual, especially for safe panel removal and component locations.

For LG refrigerators like model LSXS22423B, the most common customer-reported issue is cooling problems (refrigerator or freezer too warm). In many cases, the cause is airflow or usage related (blocked vents, frequent door openings, warm room conditions), and the troubleshooting steps in the owner's manual help you pinpoint the exact reason.

Most common symptoms we see

• Refrigerator section too warm
• Freezer section too warm
• Temperatures swing after adding a lot of food
• Food near vents freezes while other areas are warm
• Ice and water performance drops when cooling is weak

Quick checks that fix many “not cooling” complaints

Start with these basics before replacing parts:

• Give it time after install: it can take up to 24 hours for compartments to reach the set temperatures.
• Check for blocked air vents: keep packages away from the vent openings between freezer and fresh food sections.
• Reduce long door openings: frequent openings let warm, humid air in and raise temps.
• Confirm the temperature settings: incorrect control settings can make sections too warm or too cold.
• Consider the room temperature: hot locations make it harder for the refrigerator to maintain temps.
• Avoid overloading with warm food: large amounts of warm food can temporarily raise temperatures.

When it points to a part problem

If the basics look good and temperatures still drift, these are common repair directions for side-by-side refrigerators:

What you notice	Common direction	Example part on this model page
Warm temps plus weak airflow	Evaporator fan issue or frost/airflow restriction	Refrigerator freezer evaporator fan motor EAU62064602
Temps seem inaccurate or inconsistent	Temperature sensor (thermistor) issue	Refrigerator sensor 6500JB2001B
Water dispenser slow after cooling issues are resolved	Water system restriction or supply issue	LG refrigerator water filter ADQ73613401

Why it matters

Cooling problems are the root cause behind most food spoilage, soft ice, and “runs all the time” complaints. The manual’s troubleshooting section focuses on airflow, door habits, and temperature control because those are the fastest, most common fixes.

Prices vary widely by model, finish, and features; for an LG LSXS22423B side-by-side refrigerator, the most accurate way to price it is to compare current listings for that exact model number and to separate appliance cost from repair-part cost. For maintenance budgeting, use the parts list and the owner's manual to identify the exact items your refrigerator uses.

What you can price on this model page (replacement parts)

If you are shopping for parts for LG model LSXS22423B, these are examples of in-stock items shown for this model:

• LG refrigerator water filter ADQ73613401 for routine water and ice filtration
• Refrigerator water inlet valve AJU34125552 if the dispenser or ice maker is not filling
• Refrigerator dispenser ice chute door motor EAU59551204 if the ice door is not opening or closing
• Refrigerator ice maker assembly AEQ36756919 if ice production has failed
• Refrigerator freezer evaporator fan motor EAU62064602 if airflow is weak or noisy

What you are pricing	What it includes	Where to look
Whole refrigerator	Cabinet, sealed system, electronics, doors, delivery	Retail listings for LSXS22423B
Repair parts	Individual components (filter, valve, fan, ice maker)	Parts list for LSXS22423B
Installation costs	Water line hookup, leveling, door alignment	Installer quote plus manual guidance

Why the exact model number matters

LG makes many side-by-side refrigerators that look similar, but pricing changes with capacity, dispenser features, and finish. Using LSXS22423B (not just “LG side-by-side”) prevents mismatched comparisons.
