How to tell if an LG compressor is bad?
On the LG LFC24770ST, a bad compressor often shows up as warming temperatures (fresh food and freezer), little to no steady compressor hum, or repeated clicking from the lower rear area as the compressor tries to start and then shuts off. Use the LFC24770ST owner’s manual to confirm normal operating sounds and basic checks.
Quick symptoms checklist
Look for these common compressor-related signs:
- Refrigerator and freezer temperatures keep rising even though the unit has power
- Repeated clicking every few minutes from the back bottom area (start attempt then stop)
- Compressor is extremely hot to the touch (after running) and cooling is still poor
- Fans may run, lights work, but there is little or no cooling
- You hear a brief hum, then a click, and it repeats
What to check before blaming the compressor
Some issues mimic compressor failure on the LFC24770ST:
- Condenser coils clogged with dust (can cause poor cooling and long run times)
- Condenser fan not running (airflow problem at the back/bottom)
- Evaporator fan not running (no cold air circulation inside)
- Control or sensor issue (unit may not command the compressor correctly)
If you suspect a start problem (clicking), the compressor start components are worth checking along with the compressor itself, such as the refrigerator compressor overload protector 6750CL0001D and the refrigerator run capacitor EAE58905704.
Symptom-to-likely-cause guide
| What you notice | More likely | Less likely |
|---|---|---|
| Clicking every few minutes, little cooling | Start device/capacitor/overload, compressor | Door gasket issue |
| Fans run, lights on, both sections warm | Compressor not pumping, sealed system issue | Simple airflow blockage |
| Freezer cold but fridge warm | Airflow/evaporator fan issue | Compressor |
Why it matters
A compressor is the heart of the sealed cooling system. Misdiagnosing it can lead to unnecessary parts replacement, while ignoring a real compressor or start-device problem can cause food spoilage and extended run time.

Why is my LG refrigerator leaking from the bottom?
On LG model LFC24770ST, a leak from the bottom is most often caused by defrost water that cannot drain properly (a clogged or frozen defrost drain) or by a water supply leak related to the ice maker and water line connections. Start by identifying whether the water is clear (supply leak) or dirty (defrost drain).
Quick checks we recommend first
- Unplug the refrigerator and pull it forward enough to inspect the floor and rear lower area.
- Check whether the leak happens only after ice maker use or after a defrost cycle.
- Look for ice buildup on the freezer floor or under the bottom drawer.
- Inspect the water line connection at the back for drips.
- Make sure the unit is level so water flows to the drain as designed.
Most common causes (and what to do)
1) Clogged or frozen defrost drain
Defrost water should flow to a drain pan underneath. If the drain is blocked, water can overflow and leak from the bottom.
What to do:
- Remove the freezer drawer(s) and look for ice or water pooling.
- Carefully melt ice with a hair dryer on low (keep heat moving) and clear the drain opening.
- Flush the drain with warm water (a turkey baster works well).
2) Ice maker or water supply leak
If the water is clean and the leak is near the back or right after ice production, the ice maker fill system or valve may be leaking.
What to do:
- Check the water inlet valve area and tubing for seepage.
- If the valve is dripping or not closing fully, replacement is common.
Relevant parts for this model:
- LG refrigerator water inlet valve AJU73753101
- LG refrigerator ice maker assembly model AEQ72909603 AEQ72909603
Symptom guide: what the water tells you
| What you see | Most likely source | Where to focus |
|---|---|---|
| Clear water, near back | Water supply/ice maker | Valve, tubing, connections |
| Water with debris, near front | Defrost drain overflow | Drain opening, drain tube |
| Ice sheet in freezer bottom | Frozen drain | Defrost drain clearing |
Why it matters
Bottom leaks can damage flooring and can also lead to ice buildup that affects airflow and cooling performance. Fixing the drain or water supply leak early helps prevent repeat puddles and temperature issues.
For model-specific component locations and leveling guidance, use the LFC24770ST manual.

What is the problem with the LG bottom freezer refrigerator?
On the LG LFC24770ST French door refrigerator (bottom freezer drawer), there is not one single “most common” problem we can confirm for this exact model from model-specific information alone. The best approach is to match your symptom (warm fridge, no ice, frost, noise, leaks) to the troubleshooting steps in the LFC24770ST owner’s manual.
Common issues customers troubleshoot on this LG style
- Refrigerator section warm while freezer seems normal (airflow or fan related)
- Frost buildup on the freezer back panel (defrost system issue)
- Ice maker not making ice or slow ice production (water supply or ice maker issue)
- Water leaking or no water dispensing (water inlet valve or line issue)
- Lights not working when the door opens (door switch issue)
Quick checks to narrow it down
- Confirm the control settings are reasonable (many LG units target about 37°F fresh food and 0°F freezer)
- Make sure interior air vents are not blocked by food packages
- Check that doors close fully and gaskets seal all the way around
- Listen for the evaporator fan running (often easiest to hear with doors closed)
- Look for heavy frost or ice behind the freezer rear panel
Parts that often relate to these symptoms on LFC24770ST
| Symptom you see | What it can point to | Example compatible part |
|---|---|---|
| Fridge warm, freezer cold | Poor airflow in the fresh food section | LG refrigerator evaporator fan motor 4681JB1027C |
| Frost buildup, temps drift | Defrost sensing issue | Refrigerator defrost sensor assembly 6615JB2005N |
| No ice or slow ice | Ice maker or fill problem | LG refrigerator ice maker assembly model AEQ72909603 AEQ72909603 |
| No water, leaking, or weak fill | Water valve not opening correctly | LG refrigerator water inlet valve AJU73753101 |
Why it matters
Pinpointing the symptom first helps you avoid replacing the wrong part. Issues like warm temperatures or frost buildup can affect food safety and can also force longer run times that add wear to the sealed system.
