LG LFC24770ST/00 refrigerator Parts

To reset the ice maker on your LG LFC24770ST bottom-mount refrigerator, turn the ice maker power switch OFF, wait about 30 seconds, then turn it back ON. The ice maker restarts once the freezer is at 15°F (-9°C) or colder; see the owner's manual for switch location and operating details.

Quick reset steps

• Open the freezer and locate the ice maker power switch.
• Move the switch to OFF (O).
• Wait 30 seconds.
• Move the switch back to ON (I).
• Make sure the ice bin is fully seated and aligned.
• Allow time for ice production to resume (new installs can take 12 to 24 hours to start making ice).

Before you reset: confirm the basics

If the ice maker is not cycling after a reset, these checks fix most “no ice” complaints:

• Freezer temperature is 15°F (-9°C) or below
• Water supply shutoff valve is fully open
• Water line connections are not leaking
• Ice bin is not overfilled and the shutoff arm (if equipped) moves freely
• Ice-detecting sensor area is clean (frost or debris can stop ice production)

What to expect after a reset

What you see/hear	What it means	What to do
Buzzing at fill	Water valve energizing	Normal if water is connected; if not connected, switch OFF to stop buzzing
Cubes drop into bin	Harvest cycle completed	Normal operation
No ice right away	Freezer not cold enough yet or just reset	Wait for temperature to stabilize

Why it matters

A reset clears a stalled ice maker cycle and forces the unit to restart its normal sequence. If the freezer is too warm or the sensor area is frosted over, the ice maker can pause even though the switch is ON.

When a part is the likely fix

If you have proper freezer temperature and water supply but still get no ice after resetting, the ice maker assembly or water inlet valve is often the next place to check.

For the LG LFC24770ST, the most common service complaint is a cooling failure (refrigerator or freezer not staying cold). In a bottom-mount design, that symptom is most often tied to the sealed system or airflow components such as the compressor, evaporator fan, sensors, or defrost-related parts; use the owner's manual troubleshooting and safety guidance first.

What “not cooling” usually looks like

• Fresh food section warm but freezer still partly cold
• Freezer warm and ice cream soft
• Clicking, buzzing, or repeated start attempts from the machine compartment
• Frost buildup on the back wall of the freezer (airflow blocked)
• Temperatures swing even though settings look correct

Quick checks we recommend before replacing parts

1. Confirm settings and airflow: Make sure vents are not blocked by food packages.
2. Check door sealing: Look for gaps, torn gasket areas, or doors not closing fully.
3. Clean and listen: Dust buildup and a stalled fan can reduce cooling; listen for the evaporator fan when the door switch is pressed.
4. Power reset: Unplug for 5 minutes, then restore power and allow 24 hours to stabilize.
5. Safety first: Unplug the refrigerator before cleaning or inspecting internal components (per the manual).

Parts that commonly relate to cooling complaints on LFC24770ST

If your symptoms point to a specific failure, these model-matched parts are commonly involved:

Symptom	Likely area	Example model-matched part
Warm temps, compressor struggles to start	Compressor start protection	Refrigerator compressor overload protector 6750CL0001D
Warm temps, poor air circulation	Evaporator fan system	LG refrigerator evaporator fan motor 4681JB1027C
Ice maker not producing ice (with water supply OK)	Ice maker assembly	LG refrigerator ice maker assembly model AEQ72909603 AEQ72909603
Water dispenser slow or no fill to ice maker	Water inlet valve	LG refrigerator water inlet valve AJU73753101

Why it matters

Cooling problems can spoil food quickly and can also cause secondary issues like excessive frost, water leaks from defrost drain icing, and overworking the compressor. Catching airflow or door-seal issues early often prevents bigger repairs.

On an LG LFC24770ST refrigerator, a bad compressor usually shows up as warm temperatures (fresh food and freezer), little to no compressor run sound, or repeated clicking from the lower rear area as the compressor tries to start and then shuts off. Confirm basic airflow and power issues first.

Quick checks before blaming the compressor

• Make sure the refrigerator has power and the interior lights come on.
• Listen at the back bottom: a steady hum is normal; repeated click-then-silence points to a start problem.
• Check for airflow inside: if the freezer fan is not running, cooling can fail even with a good compressor.
• Clean dust from the condenser area; heavy buildup can cause poor cooling and long run times.
• Verify the doors seal tightly; warm air leaks can mimic a sealed-system problem.

What the symptoms usually mean

Symptom	Most common cause	What to check next
Repeated clicking near compressor	Overload/start device opening	Inspect/replace the refrigerator compressor overload protector 6750CL0001D
No cooling, fans running	Sealed-system or compressor not pumping	Compressor and sealed-system diagnosis
Warm fridge, freezer cold-ish	Airflow/defrost issue	Evaporator fan, frost pattern, defrost components
Loud buzzing then click	Compressor struggling to start	Overload, wiring, compressor condition

Model-relevant parts that often get involved

If the compressor is not starting or is clicking off, these parts are commonly checked in the same repair path:

• Refrigerator compressor TCA38091801 (the compressor itself)
• Refrigerator compressor overload protector 6750CL0001D (opens on overcurrent/overheat)
• Refrigerator power control board CSP30020818 (can affect compressor operation)

Why it matters

A compressor diagnosis affects both cost and downtime. Many “bad compressor” complaints are actually caused by a failed overload protector, airflow problems, or control issues. Ruling out those items first prevents unnecessary sealed-system work.

Use the manual’s built-in diagnostics

Your refrigerator includes Smart Diagnosis steps that can help capture operating data when the unit has power. Follow the procedure in the owner's manual to run Smart Diagnosis correctly.

A bottom leak on your LG LFC24770ST refrigerator is usually caused by a defrost drain that’s clogged and overflowing into the base, or a water-supply issue to the ice maker or dispenser that’s dripping down and pooling underneath. Use the owner's manual for safety and access guidance before checking components.

Quick checks that solve most bottom leaks

• Unplug the refrigerator before removing panels or working near wiring.
• Look for a sheet of ice or standing water under the freezer drawer; that points to a defrost drain problem.
• Check the water line connection and shutoff valve for slow drips.
• Inspect the ice maker fill area and tubing for leaks or a misdirected fill stream.
• Make sure the doors close fully; warm air can increase frost and drain overflow.

Most common causes (and what to look for)

Likely cause	Typical signs	What to do next
Clogged/iced defrost drain	Water under freezer, then leaking out the bottom	Thaw ice, flush the drain with hot water, clear debris
Leaking water inlet valve	Puddle appears even when not dispensing water	Inspect valve and fittings; replace if seeping (LG refrigerator water inlet valve AJU73753101)
Ice maker leak or overfill	Water trails near ice maker area, icicles, or overflow	Check fill tube alignment; inspect ice maker assembly (LG refrigerator ice maker assembly model AEQ72909603)
Door gasket not sealing	Excess frost, condensation, intermittent leaking	Clean/reshape gasket; replace if torn (example: LG refrigerator door gasket, right (noble gray) ADX73350633)

Why it matters

Water collecting in the base can damage flooring, create odors, and lead to ice buildup that blocks airflow. Fixing the source early helps your refrigerator cool efficiently and prevents repeat leaks.

When a leak points to a bigger cooling problem

If the refrigerator is also warm, unusually noisy, or running constantly, address cooling issues first because heavy frost and poor airflow can worsen drain overflow. For fan-related cooling symptoms, the evaporator fan motor is a common checkpoint (LG refrigerator evaporator fan motor 4681JB1027C).
