LG LDCS24223S/01 refrigerator Parts

For LG model LDCS24223S, the most common “no ice” complaint is usually a water supply issue (shutoff valve not fully open, low water pressure, kinked line, or a restricted filter), followed by the icemaker being turned off or blocked by ice buildup. Use the LDCS24223S manual to confirm icemaker ON/OFF and basic checks.

Quick checks we recommend first

• Confirm the icemaker power switch is set to ON (I).
• Make sure the refrigerator is actually cold enough; a warm freezer reduces ice production.
• Verify the household water shutoff valve is fully open.
• Check for a kinked or pinched water line behind the refrigerator.
• If ice tastes bad, is small, or production is slow, replace the water filter (if equipped).
• Dump old ice and clean the ice bin if cubes are clumping or smell stale.

Model-specific specs that affect ice production

Your LDCS24223S manual calls out these common “normal” conditions that can look like a problem:

Item	What to expect	Why it matters
New install or recently reconnected water	12 to 24 hours to start making ice	Prevents unnecessary part replacement
Water pressure	Typically needs to be in the 20 to 120 PSI range (varies by configuration)	Low pressure causes small cubes or no fill
Ice bin/sensor area	Must be clear of frost and debris	A blocked sensor can stop cycling

When it’s likely a part issue

If water pressure is good, the line is clear, and the icemaker is ON but you still get no ice, the icemaker assembly or inlet valve can be the next suspects.

• If the icemaker won’t cycle or won’t eject cubes, consider the LG refrigerator ice maker assembly model AEQ72909603 AEQ72909603.
• If the icemaker mold is dry (no water fills), consider diagnosing the LG refrigerator water inlet valve AJU73753101.

Why it matters

Ice problems are often caused by setup, temperature, or water supply restrictions, not a failed icemaker. Ruling out water pressure, kinks, and filter restriction first saves time and avoids replacing good parts.

On the LG LDCS24223S bottom-mount refrigerator, the most reliable “reset” is turning the icemaker OFF, then back ON, and allowing time for the freezer to reach 15°F or below; ice production typically resumes within 12 to 24 hours once conditions are correct. See the icemaker section in the LDCS24223S manual.

Quick reset steps (LDCS24223S)

• Open the freezer and locate the icemaker power switch.
• Move the switch to OFF (O).
• Wait 30 seconds to 5 minutes.
• Move the switch back to ON (I).
• Close the freezer and wait for a harvest cycle; discard the first few batches if the unit was recently installed or unused.

What to check if it still won’t make ice

These checks matter more than repeatedly resetting:

• Freezer temperature: the icemaker won’t operate until the freezer is at 15°F (-9°C) or below.
• New install or recent power loss: allow up to 24 hours for temperatures to stabilize and ice to start.
• Water supply: confirm the shutoff valve is fully open and the supply line is not kinked.
• Ice bin and shutoff arm/sensor: make sure the bin is seated correctly and nothing blocks the shutoff mechanism.
• Ice-detecting sensor area: clear any frost or debris that could interrupt sensing.

When a part may be involved

If the freezer is cold enough and water supply is good but the icemaker never cycles, the icemaker module itself can be the issue. For this model, the compatible replacement is the LG refrigerator ice maker assembly model AEQ72909603 AEQ72909603.

Symptom-to-part quick guide

Symptom	Most likely area to inspect	Example compatible part for LDCS24223S
No ice, freezer cold, water supply OK	Icemaker assembly	AEQ72909603
No ice and no water entering icemaker	Water inlet valve / supply	AJU73753101

Why it matters

A reset only restarts the icemaker’s on/off state; it won’t overcome warm freezer temps, low water pressure, a blocked sensor, or a failed icemaker assembly. Verifying those basics first prevents wasted time and repeat no-ice problems.

On LG model LDCS24223S, ice building up on the freezer floor is most often caused by defrost water not draining properly; the meltwater refreezes under the drawer and forms a sheet of ice. Clearing the drain path and confirming the drain tube is open usually fixes it; see the LDCS24223S manual.

What to check first (quick diagnosis)

• Look for a solid ice sheet under the lower basket; that points to a drain issue.
• Check for water droplets or frost on the back freezer panel; heavy frost can overwhelm the drain.
• Confirm the freezer drawer closes fully; warm, humid air increases frost and meltwater.
• Listen for the evaporator fan; poor airflow can contribute to frost buildup.

How we recommend fixing it

1. Unplug the refrigerator.
2. Empty the freezer, remove the baskets/drawer as needed.
3. Manually defrost the ice on the freezer floor (towels plus a bowl of hot water in the compartment works well). Avoid sharp tools.
4. Clear the defrost drain opening at the back of the freezer compartment using warm water (a turkey baster works) until it flows freely.
5. Verify the drain tube is open all the way to the drain pan area; if it’s split, restricted, or deformed, replace the refrigerator drain tube 5251JA3003D.

When it’s more than a clogged drain

If the drain keeps freezing over again, one of these may be contributing:

• Door not sealing (gasket not sealing, drawer not closing)
• Excessive door openings or high humidity
• Defrost system problem (heater or sensor not working consistently)

Common causes and what you’ll usually see

Symptom	Most likely cause	What to do next
Ice sheet only on freezer floor	Drain blocked or slow	Clear drain; inspect drain tube
Heavy frost on back freezer panel	Air leak or defrost issue	Check door seal; consider defrost components
Water leaking out when ice melts	Drain not flowing to pan	Confirm drain tube routing and flow

Why it matters

When defrost water can’t drain, it refreezes and can eventually cause drawer sticking, water leaks, and temperature swings that affect food quality.
