LG LDC24370ST/02 bottom-mount refrigerator Parts

For an LG LDC24370ST bottom-mount refrigerator, an LG-branded water filter is worth it when you want the best fit, fewer leak issues, and consistent filtration performance; the main downside is higher cost versus third-party filters.

What you get by using an LG filter

• Better chance of a proper seal in the filter head (helps prevent drips and bypass)
• More consistent taste and odor improvement (chlorine reduction is the most noticeable)
• Less risk of flow problems caused by poor filter construction
• Simpler replacement experience because the fit is designed for LG housings

When a cheaper filter can make sense

If your household uses very little filtered water or you are mainly trying to reduce cost, a lower-priced compatible filter can be appealing. We still recommend prioritizing correct fit and a good seal over price.

Quick comparison

Option	Best for	Trade-off
LG-branded filter	Reliability, fit, fewer nuisance leaks	Higher upfront cost
Third-party “compatible” filter	Lower cost per change	More variability in fit, flow, and performance

Why it matters

A refrigerator water filter that does not seal correctly can cause slow dispensing, odd taste, or water leaks that damage shelves, drawers, and flooring. Using the right filter helps protect the water system and keeps ice and drinking water tasting clean.

Helpful resources for this LG refrigerator

• Check the replacement steps and filter location in the LDC24370ST owner's manual
• Use our guidance in how to change the water filter in an LG refrigerator to avoid air in the line and improve flow after replacement

Frost buildup in the freezer of your LG LDC24370ST bottom-mount refrigerator almost always comes from warm, moist air getting into the freezer or from a defrost system problem that lets ice accumulate on the evaporator. Start by checking door sealing and airflow, then move to defrost components.

Quick checks that fix most frosting

• Make sure the freezer door closes fully and nothing is holding it open (bags, bins, ice bucket).
• Inspect the gasket for gaps, tears, or hardened sections; clean it with mild soap and water.
• Confirm drawers and rails are seated correctly so the door can shut squarely.
• Avoid frequent door openings and letting the door stand open while loading groceries.
• Set the freezer to a typical target of 0°F and the refrigerator to 37°F.

Most common causes (and what to do)

Likely cause	What you’ll notice	What to check next
Door not sealing	Frost near the front/edges, snow on packages	Gasket condition, door alignment, obstructions
Defrost system issue	Heavy frost behind the rear freezer panel, weak cooling	Defrost sensor, fan operation, control issues
Airflow blocked	Frost in one area, temps swing	Vents blocked by food, overpacked freezer
High humidity	Frost after humid weather or lots of openings	Reduce openings, cool food before loading

Parts that commonly relate to frosting on this model

If frost is heavy behind the back panel, these model-matched parts are common suspects:

• Refrigerator defrost sensor assembly 6615JB2005N (helps the control manage defrost timing)
• LG refrigerator evaporator fan motor 4681JB1027C (moves cold air; poor airflow can worsen icing)
• Refrigerator freezer door gasket ADX73350955 (prevents moist air leaks)

Why it matters

Frost buildup reduces airflow across the evaporator, which makes the freezer warm up, the refrigerator section run warmer, and the compressor run longer. Fixing the air leak or defrost issue restores normal cooling and efficiency.

Model-specific help

Use the LDC24370ST owner's manual for the correct temperature settings, airflow locations, and any defrost or diagnostic guidance specific to your LG bottom-mount design.

Cooling problems are the most common issue we see across LG refrigerators, including the LG LDC24370ST; symptoms include a warm fresh-food section, a soft-freezing freezer, or temperatures that swing. The next most common trouble spots are ice maker and water supply issues, plus airflow and frost problems.

What “cooling problem” usually looks like

• Refrigerator section is warm but the freezer seems closer to normal
• Freezer is warm and ice production slows or stops
• Food spoils faster or drinks never get cold
• You hear the fan running but temperatures do not recover
• Frost builds up on the back wall or around vents

Quick checks we recommend first (before replacing parts)

1. Confirm settings: fridge about 37°F and freezer about 0°F.
2. Make sure vents are not blocked by food packages.
3. Clean condenser area (dust buildup can raise temps).
4. Check door closing and gasket seal all the way around.
5. If you have an ice maker, confirm the water supply valve is fully open.

For model-specific operating details and control settings, use the LDC24370ST owner's manual.

Common causes and the parts that often relate

Symptom	Common cause	Example related part for LDC24370ST
Warm temps, weak airflow	Evaporator fan not moving air	LG refrigerator evaporator fan motor 4681JB1027C
Frost buildup, warming over time	Defrost system sensing issue	Refrigerator defrost sensor assembly 6615JB2005N
Ice maker not filling	Water supply problem or valve issue	LG refrigerator water inlet valve AJU73753101
Door ajar light issues, intermittent cooling	Door not registering closed	Refrigerator door switch 6600JB1010A

Why it matters

A refrigerator that cannot hold temperature safely can spoil food quickly and can also run longer than normal, which increases wear on components like the evaporator fan motor and control system.

Helpful prevention tip

If your model uses a water filter, replacing it on schedule helps prevent low flow that can affect ice maker performance; see how to change the water filter in an LG refrigerator.

On the LG LDC24370ST bottom-mount refrigerator, water leaking from underneath is usually caused by a defrost drain problem (ice or debris backing up and overflowing), a door gasket that is letting in excess moisture, or a water supply leak feeding the ice maker or inlet valve.

Quick checks we recommend first

• Look for water only after a defrost cycle (often points to a defrost drain issue).
• Check whether the leak happens only when the ice maker fills (often points to the water inlet valve or supply line).
• Inspect the freezer door seal for gaps, rips, or areas that do not contact the cabinet.
• Verify the refrigerator is level; a tilt can change where water runs and pools.
• Check the drain pan for cracks and confirm it is seated correctly.

Most common causes and what to do

1) Clogged or frozen defrost drain

A blocked drain can force meltwater to overflow into the freezer bottom and then leak out.

• Unplug the refrigerator.
• Remove the freezer drawer and rear panel as needed.
• Melt any ice with warm water (not sharp tools).
• Flush the drain with hot water until it runs freely to the drain pan.

2) Water supply leak (ice maker or valve)

If you have an ice maker, a small seep at the valve or line can drip down and out.

• Inspect the valve body and fittings for mineral tracks or wetness.
• Check the plastic water line for kinks, rub-through, or a loose compression nut.
• If the valve is weeping or not closing fully, replacement is typical.

Parts that commonly relate to bottom leaks on this model

Symptom pattern	Likely area	Example part for this model
Leak happens during/after defrost	Defrost drain, drain trough, drain pan	(Drain parts vary by diagram)
Leak happens when ice maker fills	Water valve, water line fittings	LG refrigerator water inlet valve AJU73753101
Moisture, frost, or water near door edge	Door seal	Refrigerator freezer door gasket ADX73350955

Why it matters

Water under the refrigerator can damage flooring and can also indicate airflow or defrost issues that lead to ice buildup and poor cooling. Fixing the source early helps protect the compressor and prevents recurring puddles.
