LG LSC22991ST/00 refrigerator Parts

LG “zero clearance” refers to a hinge and door design that lets your LG LSC22991ST refrigerator open with minimal side clearance, so you can place it closer to a wall or adjacent cabinets for a more built-in look while still accessing drawers and bins.

What “zero clearance” changes in real use

• You can install the cabinet closer to a side wall without the door edge immediately hitting.
• Door swing is designed to reduce how far the door protrudes past the cabinet side.
• You typically get better access to shelves and crispers in tighter kitchen layouts.
• It helps when the refrigerator sits at the end of a cabinet run.
• You still need clearance behind and above for airflow and service access.

Quick check: is your issue really clearance-related?

Use this checklist before moving the refrigerator:

• Door hits the wall before opening far enough to pull out bins.
• Crisper or freezer basket binds when you try to slide it out.
• Door does not open smoothly (hinge resistance or rubbing).
• Refrigerator is not level, causing the door to swing or sag.
• Cabinet trim or a baseboard is blocking the door.

Clearance vs. common installation needs

Topic	What it affects	What to do
Side clearance	Door swing near walls/cabinets	Confirm hinge style and required gap in the LSC22991ST owner's manual
Rear clearance	Cooling performance, noise	Keep space for condenser airflow and cleaning
Leveling	Door alignment, sealing	Level front-to-back and side-to-side
Door seal contact	Frost, warm temps, sweating	Make sure gaskets fully contact the cabinet

Why it matters

Tight clearances can cause daily usability problems (stuck drawers, limited access) and can also lead to poor door sealing if the cabinet is twisted or the door is forced against an obstruction. Setting the correct clearances and leveling protects cooling performance and helps prevent moisture and frost issues.

For the LG LSC22991ST side-by-side refrigerator, the exact purchase price depends on where and when it was sold; on our model page we list replacement part prices (not the full refrigerator). For example, common LSC22991ST parts range from about $10 to over $600, depending on the component.

What you can expect to pay (parts for LG LSC22991ST)

Here are real examples of replacement parts we show for this model:

• Compressor: typically the highest-cost repair part
• Electronic control board and dispenser controls: often mid-to-high cost
• Water filter and dispenser switches: typically lower cost routine items
• Ice maker parts: mid-range, depending on the assembly

Item type (LSC22991ST)	Example part	Typical use	Price range you’ll commonly see
Cooling system	Refrigerator compressor TCA38091801	Restores cooling when the compressor fails	High
Water system	LG refrigerator water filter ADQ73613401	Improves taste and reduces contaminants	Low to mid
Dispenser	LG refrigerator dispenser switch 6600JB3001C	Fixes dispenser lever not activating	Low

How to estimate your total repair cost

Parts are only one piece of the total. Your out-of-pocket cost usually depends on:

• Which symptom you’re fixing (no cooling, no ice, no water, leaking)
• Whether the repair is DIY or requires a sealed-system technician
• How many parts are replaced at the same time (for example, filter plus water tube fitting)
• Whether the refrigerator is still within the warranty period described in the owner's manual

Why it matters

Side-by-side refrigerators like the LG LSC22991ST can be economical to keep running when the issue is a wear item (filter, switch, ice maker component). Larger cooling-system repairs (compressor or sealed system) are the most expensive and usually drive the repair-versus-replace decision.

For the LG LSC22991ST side-by-side refrigerator, the most common customer-reported issue is a cooling problem, where the refrigerator or freezer warms up because the sealed system is not removing heat efficiently. In many cases, the root cause is in the compressor circuit or airflow and defrost components; use the LSC22991ST owner's manual troubleshooting section to narrow it down.

Quick checks we recommend first

• Confirm the controls are set correctly and not turned off.
• Listen for the compressor and fans; unusual clicking can point to a start/overload issue.
• Make sure the unit is not in a normal defrost cycle (cooling pauses briefly during defrost).
• Check for blocked air vents inside the compartments (overpacked shelves restrict airflow).
• Clean dust from the condenser area; restricted airflow makes the refrigerator run too long.
• If you have dispenser or ice issues at the same time, check the filter and water supply.

Common causes and the parts that often fix them

If the refrigerator is warm, these are the most frequent repair paths for this model family:

Symptom	Most likely system	Example parts for LSC22991ST
Not cooling at all or warms quickly	Sealed system / compressor circuit	Refrigerator compressor TCA38091801, refrigerator compressor overload protector 6750CL0001D
Runs a lot, temps swing, frost buildup	Defrost system / airflow	Refrigerator defrost heater 5300JB1114Z, refrigerator defrost sensor EBD61246710
Ice or water dispensing problems	Dispenser / ice system / filtration	LG refrigerator water filter ADQ73613401, LG refrigerator dispenser switch 6600JB3001C

Why it matters

A refrigerator that runs too long or can’t hold temperature can lead to food spoilage and higher energy use. Catching airflow restrictions, defrost problems, or a failing compressor circuit early helps prevent bigger, more expensive repairs.

When to stop and get service help

We recommend contacting Sears PartsDirect support or a qualified technician if:

• The compressor is extremely hot to the touch, or you smell electrical burning.
• Breakers trip when the refrigerator tries to start.
• You see repeated warming even after cleaning the condenser and confirming settings.

The LG LSC22991ST side-by-side refrigerator has 21.6 cubic feet of total capacity. You can confirm the exact listed capacity and the refrigerator versus freezer breakdown in the LSC22991ST owner's manual.

Quick specs snapshot

Here is the key number most shoppers and installers need.

Model	Refrigerator type	Total capacity
LSC22991ST	Side-by-side refrigerator	21.6 cu. ft.

Where to verify capacity on the refrigerator

If you want to double-check what is printed for your unit, use these common locations.

• Look in the Specifications section of the LSC22991ST owner's manual
• Check the rating label inside the fresh food compartment (often on a side wall)
• Use the value labeled Total capacity (not just refrigerator or freezer)
• Match the label to the full model format (LSC22991ST/00)

Why it matters

Capacity (cubic feet) helps you compare storage space accurately, plan shelf and bin organization, and confirm fit for accessories such as a replacement LG refrigerator water filter ADQ73613401.
