Can I replace fridge parts myself?
Yes, for LG model SKSFD3613S, we can replace many common refrigerator parts ourselves (filters, some dispenser and ice maker components) if we unplug power first and follow the safety steps in the owner's manual. For sealed-system, LED lighting, or complex electrical repairs, we use a qualified technician.
What you can usually DIY on this model
These jobs are typically straightforward with basic tools and careful handling:
- Replace the refrigerator water filter (routine maintenance)
- Replace the refrigerator air filter (odor control)
- Troubleshoot and replace some ice maker components
- Replace some dispenser-related parts (switches, chute door motor)
- Basic cleaning and maintenance (condenser cover and vents)
Repairs we do not DIY (safety and skill)
The manual calls out repairs that should be handled by qualified service, and we follow that guidance.
- Sealed-system work (compressor, refrigerant, evaporator system)
- Interior LED lighting service
- Any repair involving damaged power cord or electrical hazards
Quick safety checklist before any repair
- Unplug the refrigerator before cleaning or repairing
- Keep hands clear of pinch points around doors and hinges
- Use two or more people for door or drawer removal
- Do not remove panels that cover the condenser coil area

How do you reset the bottom ice maker?
On the LG SKSFD3613S bottom-mount refrigerator, we reset the bottom ice maker by turning the icemaker power switch OFF, then back ON, and confirming the freezer is cold enough for ice production (15 °F or below). Use the ice bin removal steps in the owner's manual to access the icemaker safely.
Quick reset steps (bottom ice maker)
- Remove the ice bin (lift slightly, then pull out slowly).
- Move the icemaker power switch to OFF (O).
- Wait 30 seconds.
- Move the icemaker power switch back to ON (I).
- Reinstall the ice bin (insert at a slight angle, then push in fully).
- Allow time for ice production; the icemaker starts once it reaches 15 °F (–9 °C) or below.
What to check if it still will not make ice
- Water supply: Make sure the water line is connected and the shutoff valve is open.
- Freezer temperature: Set the freezer colder and give it time to stabilize.
- Ice shutoff: Make sure the shutoff arm moves freely (if equipped) or the sensor path is clear.
- Ice bin and chute: Clear frost or clumped ice; dispensing cubed ice periodically helps reduce frost buildup.
- Dispenser doors: Close all refrigerator doors completely; ice will not dispense with a door open.
Common causes and the most likely fix
| Symptom | Most likely cause | What we do first |
|---|---|---|
| No ice at all | Icemaker turned OFF or freezer too warm | Switch ON; confirm 15 °F or below |
| Ice tastes or smells off | Old ice or dirty bin | Empty, wash, dry bin; make fresh ice |
| Too much ice | Shutoff arm/sensor blocked | Empty bin; clear obstruction; wait 24 hours |
| Ice not dispensing | Frost blockage or stuck cubes | Remove bin; clear passage; break up clumps |
Why it matters
Resetting the icemaker correctly prevents unnecessary part replacement and helps protect the icemaker from running without water. If you hear buzzing and the water line is not connected, turning the icemaker OFF stops the valve from energizing.

What is the most common problem with the LG refrigerator?
For the LG SKSFD3613S bottom-mount refrigerator, the most common customer-reported issue is a cooling problem (refrigerator not cooling or temperatures not holding). In many cases, the cause is something simple such as Demo Mode being on, incorrect temperature settings, or normal defrost-related temperature swings; our owner's manual troubleshooting section walks you through these checks.
Most common symptoms you will notice
- Fresh food section is warm but lights and display still work
- Freezer temperature rises, then returns to normal after a while
- Clicking sounds as the unit cycles (often normal)
- Frost buildup or inconsistent temperatures
- Food freezing in the refrigerator section (control set too cold or room too cold)
Quick checks that fix many “not cooling” calls
- Confirm Demo Mode is off: Demo Mode lets the lights and display work while disabling cooling.
- Verify the controls are not set to OFF (some models have an OFF setting).
- Give it time after defrost: temperatures can rise slightly during defrost; wait about 30 minutes and recheck.
- Adjust temperature one step at a time: then wait for the temperature to stabilize.
- Check room temperature: LG notes performance issues can occur in very cold locations (do not operate below about 55 °F).
What’s normal vs. what points to a problem
| What you notice | Often normal | More likely a problem |
|---|---|---|
| Clicking | Defrost/control cycling | Constant clicking with no cooling recovery |
| Dripping sound | Water into drain pan during defrost | Water pooling on floor repeatedly |
| High-pitched/pulsating | High-efficiency compressor running | Loud, persistent noise plus warm temps |
Parts that commonly relate to cooling and airflow issues
If the quick checks do not restore cooling, these model-specific parts are often involved in diagnosis and repair:
- LG refrigerator compressor TCA36811409
- Refrigerator defrost sensor assembly 6615JB2005R
- LG refrigerator freezer air duct cover and fan assembly AEB75844605
Why it matters
Cooling problems can lead to food spoilage quickly, and “normal operation” sounds can be mistaken for failures. Starting with control settings, Demo Mode, and defrost behavior helps you avoid unnecessary part replacement and narrows the repair to the right system (controls, defrost, airflow, or sealed system).

Why is the bottom of my LG refrigerator leaking?
A leak at the bottom of your LG SKSFD3613S bottom-mount refrigerator is usually caused by a clogged defrost drain (water overflows into the base), a problem in the ice maker or water supply line, or a water inlet valve that is seeping or not closing fully. Use the owner's manual safety guidance before inspecting.
Quick checks (fastest ways to narrow it down)
- Look for water source: clear water near the front often points to the dispenser or water line; water after a defrost cycle often points to the defrost drain.
- Check the water filter seating: a loose or mis-seated filter can drip and run down to the bottom.
- Inspect the ice maker fill area: look for ice buildup or a small stream during fill.
- Check water pressure: models with a water filter typically need 20 to 120 psi; low or unstable pressure can contribute to valve and ice maker issues.
- Confirm the unit is level: a refrigerator that tilts forward can let water run out instead of into the drain pan.
Most common causes and what to do
| Likely cause | What you typically see | What to do next |
|---|---|---|
| Clogged defrost drain | Water under crisper or pooling then leaking to floor | Clear the drain opening and flush with warm water; clean debris and food particles. |
| Water inlet valve leaking | Slow drip even when not dispensing | Test for seepage; replace the valve if it will not shut off (common fix: refrigerator water inlet valve AJU75632502 or refrigerator water inlet valve MJX64471402). |
| Ice maker or fill tube issue | Ice clumps, overflow in ice bin area | Inspect for a frozen fill tube or misaligned fill; replace the ice maker if it is leaking (example: refrigerator ice maker AEQ73449909). |
| Filter or tubing connection leak | Drips at rear or under filter housing | Reseat the filter (example: LG lt1000p refrigerator water filter AGF80300704) and check fittings (example: refrigerator water tube fitting 4932JA3002C). |
Why it matters
Water at the bottom can damage flooring and can also signal a defrost drainage problem that may lead to ice buildup and reduced cooling performance over time.
Safety notes we follow before inspecting
- Unplug the refrigerator or disconnect power before cleaning or checking internal areas.
- Do not spray water directly on the refrigerator.
- Avoid putting hands near the bottom surface when moving or checking underneath.
