What is the most common problem with an LG refrigerator?
Cooling problems are the most common issue we see with LG refrigerators, including the LG LDC24370ST. Symptoms usually include warm refrigerator temperatures, a freezer that will not stay frozen, or inconsistent cooling caused by airflow, defrost, fan, or sealed-system problems. See the LDC24370ST owner's manual for model-specific operating and care guidance.
- Fresh food section feels warm but the freezer seems OK (or the reverse)
- Temperature swings, food spoiling faster than normal
- Clicking, buzzing, or the unit repeatedly trying to start
- Frost buildup on the freezer back wall (restricted airflow)
- Ice maker stops producing ice or produces small/hollow cubes
- Confirm settings: Set refrigerator to 37°F and freezer to 0°F; allow 24 hours to stabilize.
- Door sealing and loading: Make sure doors close fully and vents are not blocked by food packages.
- Condenser area care: Keep dust buildup under control; our manual cautions not to remove the panel covering the condenser coil area.
- Power reset: If you unplug the refrigerator, wait at least 5 minutes before plugging it back in (helps protect the compressor).
If basic checks do not help, these model-matched parts are often involved in cooling complaints:
| Symptom | Likely system | Example model-matched part |
|---|---|---|
| Warm temps, compressor will not stay running | Sealed system / start protection | Refrigerator compressor overload protector 6750CL0001D |
| Warm temps, weak airflow, noisy fan | Evaporator airflow | LG refrigerator evaporator fan motor 4681JB1027C |
| Frost buildup, defrost problems | Defrost sensing | Refrigerator defrost sensor assembly 6615JB2005N |
A refrigerator that is not cooling correctly can lead to food safety issues and can also overwork major components like the compressor. Catching airflow restrictions, sensor issues, or start-protection problems early helps prevent bigger failures.
We recommend matching by model number LDC24370ST and confirming the part location in the diagrams before ordering. You can order parts from the list for this model, or search by model on Sears PartsDirect.

How does an LG ice maker know when to dump ice?
On the LG LDC24370ST ice maker, the dump (harvest) cycle is controlled by the ice maker’s internal controls and shutoff system: it keeps making ice until the bin reaches the shutoff arm level (or the electronic shutoff sensor path is blocked), then it stops producing ice until the ice level drops again. See the LDC24370ST owner's manual for the exact icemaker type and operating details.
LG uses one of these “ice full” methods on this style of bottom-mount refrigerator:
- Mechanical shutoff arm: when ice piles up to the arm, the arm can’t drop; ice production stops.
- Electronic ice-detecting sensor: when frost or an obstruction blocks the sensor “path,” ice production can stop or act erratically.
- ON/OFF switch logic: if the ice maker switch is OFF, it will not cycle regardless of ice level.
These are the most common causes of odd harvest timing or poor ice production:
- Make sure nothing interferes with the sweep of the shutoff arm (if equipped).
- Keep the ice-detecting sensor area clean; frost or debris can interrupt operation.
- Confirm the freezer is cold enough; for normal ice production, set the freezer to 0°F.
- Reduce long door openings; warm air slows freezing and delays normal cycling.
- Verify the water supply is fully on and the line is not kinked; low flow can affect cube formation.
| Feature | What it monitors | What happens when “full” | Common issue |
|---|---|---|---|
| Shutoff arm | Ice level in bin | Arm can’t move freely; ice maker stops | Arm blocked by ice clumps or bin misalignment |
| Electronic sensor | Clear path between sensors | Path blocked; ice maker stops | Frost or items blocking sensor path |
The ice maker does not “guess” when to dump; it relies on temperature, timing, and the shutoff system to keep cube size consistent and prevent overfilling. When the shutoff arm or sensor is obstructed, you can get no ice, too much ice, or irregular cycling.
If you need to replace the ice maker assembly for this model, we list the LG refrigerator ice maker assembly model AEQ72909603 AEQ72909603 for LG LDC24370ST, and you can also search by model on Sears PartsDirect.

Is it worth repairing a 10 year old LG refrigerator?
Yes; repairing a 10-year-old LG bottom-mount refrigerator like model LDC24370ST is worth it when the failure is a common service part and the cabinet and doors are in good condition. The decision mainly depends on total repair cost and whether the problem is sealed-system related.
- Repair first for airflow, defrost, sensor, and water/ice issues
- Be cautious with sealed-system work (compressor, evaporator, refrigerant circuit)
- Repair makes sense when the fix restores reliable cooling in one visit
- Replace sooner if you have repeated cooling failures or major cabinet/door damage
| Repair type | Examples for LDC24370ST | Usually worth it at 10 years? |
|---|---|---|
| Airflow and cooling circulation | Refrigerator evaporator fan motor 4681JB1027C | Yes |
| Defrost and temperature sensing | Refrigerator defrost sensor assembly 6615JB2005N, refrigerator temperature sensor 6500JB2002X | Yes |
| Water and ice | LG refrigerator water inlet valve AJU73753101, LG refrigerator ice maker assembly model AEQ72909603 | Yes |
| Sealed system | Refrigerator compressor TCA38091801, refrigerator filter dryer ADH73150208 | Sometimes |
A 10-year-old refrigerator often has useful life left. Choosing the right repair (fan motor, sensor, valve) protects food temperatures and prevents repeat breakdowns; sealed-system repairs cost more because they require specialized labor.
Use the troubleshooting and safety guidance in the LDC24370ST owner's manual to match symptoms before replacing parts. You can order model-specific parts from the parts list for LDC24370ST, or search by model number on Sears PartsDirect.
