Locate the evaporator fan assembly by removing the interior rear panel–this part circulates cold air and fails most often due to ice buildup. Reference position EAU62869301 in the service manual; replacing it requires a T20 Torx driver and disconnecting the door switches to avoid triggering diagnostic errors.
The water filter housing (ADQ74793401) mounts behind the crisper drawer; cracks here cause slow dispensing. Verify the inlet valve (ADQ31464601) before ordering–it sits at the base, controlled by a 120V solenoid that degrades after 6–8 years.
Door gaskets (MWP20474701) seal only when heated with a hair dryer; cold seals warp and leak. Replace hinges (ADQ72911203) if alignment shifts–tighten screws in sequence: upper left, then lower right to prevent binding.
LED lighting strips (EBR73905106) connect via fragile ribbon cables–bend them sharply and the display flickers. The PCB (EBR38495106) behind the control panel demands anti-static precautions; a 2.5mm bipolar screwdriver removes the cover screws hidden under adhesive pads.
Check the compressor start relay (EAU87773601) first if the unit hums but won’t cool–attach a multimeter to terminals 1 and 3; readings below 15 ohms confirm failure. Capacitors (EBR73829303) swell visibly; discharge them safely before handling to prevent 300V shocks.
LG Refrigerator Model Components: Step-by-Step Service Reference
Locate the evaporator fan motor behind the interior rear panel–access requires removing screws securing the back wall. Model EAU62795001 is the most common replacement, but verify by checking the label on the original unit before ordering. Tool list: Phillips #2 screwdriver, 5/16″ nut driver, and needle-nose pliers for disconnecting wiring harnesses.
Replace door gaskets by first heating the old seal with a hairdryer to soften adhesive; peel away slowly to avoid tearing. Part numbers vary by door side–ADQ36000125 (left) and ADQ36000126 (right)–and must be aligned precisely within the channel before pressing firmly along the entire perimeter. Test seal integrity by sliding a dollar bill between the gasket and frame; if it moves freely, re-seat the gasket.
For water filter housing repairs, depress the release tab on the filter assembly located in the upper right corner while pulling firmly downward. Model ADP74317204 fits this unit, but dimensional checks are critical–measure outer diameter (85 mm) and length (190 mm) to confirm compatibility. Flush the new filter with 2–3 gallons of water to clear carbon fines before reinstalling.
Address ice maker malfunctions by inspecting the auger motor (part EBR64201003) beneath the ice bucket–remove the bucket’s front cover to expose the motor shaft. Listen for humming without rotation; if present, replace the motor assembly rather than attempting gear adjustments. The drive gear (part EBR74600001) often fails independently and should be checked for wear if ice dispensing becomes erratic.
Before servicing the control board, disconnect power and discharge capacitors by shorting the terminals with an insulated screwdriver–voltages persist up to 15 minutes after unplugging. Part EBT68830101 mounts vertically behind the fresh food compartment’s upper rear corner; label all connectors with masking tape prior to removal to ensure correct reconnection sequence.
Clean condenser coils biannually using a coil brush (1/2″ width) followed by vacuuming debris–units with smart cooling systems prioritize this maintenance, as clogged coils trigger error code “CF” within 48 hours. The condenser fan (part EBR40952301) spins freely when operational; replace if rotation stops or emits grinding noises, indicating bearing failure.

Troubleshooting Missing Schematics
Contact LG’s Parts Department at 1-800-243-0000, quoting the full model string found on the unit’s interior left wall. Representatives can email a secure schematic link within 24 hours. Alternatively, visit an authorized service center–technicians maintain physical binders of rare breakouts, including discontinued trim kits or European-voltage components.
How to Locate Spare Components Using the LG Refrigerator Service Blueprint
Begin by retrieving the official service manual for the model in question. The schematic is typically found in section 3, labeled “Exploded View,” where components are arranged by subsystem–compressor, evaporator, control board, and door assemblies. Each part is assigned a reference number matching the bill of materials on the adjacent page. Cross-reference these numbers with the LG spare parts catalog or authorized distributors to avoid counterfeit substitutes, which may lack compatibility or safety certifications.
Trace electrical connections first if troubleshooting cooling failures. The wiring harness, illustrated as dashed lines in the blueprint, connects critical elements like the start relay, thermistor, and defrost heater. Discoloration, brittle insulation, or burnt terminals on these wires often indicate failure points. Replace entire harnesses rather than splicing when damage is detected–partial repairs risk intermittent faults or safety hazards.
For mechanical breakdowns, focus on high-wear items listed in the upper-right quadrant of the blueprint. Examples include:
- Door gaskets (ref. #4030JJ4004A) – Measure seal compression; flattened edges confirm need for replacement.
- Evaporator fan motor (ref. #EAU62282301) – Test for continuity before ordering; bearing failure produces a distinct whine.
- Water inlet valve (ref. #AMZ30176902) – Check for 120VAC input; clogged screens require ultrasonic cleaning or full swap.
The control panel (ref. #EBR84262401) demands careful handling. Static discharge can corrupt firmware, so ground yourself before touching the display or mainboard. Verify error codes via the diagnostic mode (hold “Cooler” and “Freezer” buttons for 5 seconds) before ordering replacement modules. Note that LCD screens and membrane switches are often sold as a single assembly, increasing cost but ensuring proper interfacing.
For internal components like shelves and crisper drawers, note the exact dimensions in the blueprint’s “Cabinet Parts” section. LG uses tempered glass (3mm thickness) for shelves, which cracks under uneven loads; replacements must match the original’s width within 1mm to prevent misalignment. Drawer slides (ref. #MAN62077804) are plastic and prone to shearing–upgrade to stainless steel aftermarket kits if frequent failure occurs.
Order directly through LG’s Parts Portal using the exact reference numbers. Generic search terms like “refrigerator fan” yield thousands of results, but only specific part codes ensure compatibility. Include the model’s serial number for warranty validation, especially for sealed-system components like compressors. Keep the schematic during installation–reassembly tolerances are tight, and misplaced screws or washers can void seals or damage insulation.
Step-by-Step Disassembly for LG Refrigerator Model LFX26
Unplug the appliance and move it to a well-lit workspace before beginning. Remove the lower kick plate by pressing the release tabs on either side–located 3 inches from the outer edges–and sliding it forward. Disconnect the drain tube by squeezing the plastic clamps at the base of the rear panel, then lift the tubing clear. Next, access the compressor cover by unscrewing the four 8mm bolts securing it; use a socket wrench to avoid stripping. The evaporator fan is held by two 6mm screws–remove these first, then gently disconnect the wiring harness by lifting the white latch before pulling the plug.
Handling Internal Components
Detach the icemaker assembly by releasing the three quick-release clips along the top edge and unthreading the single 7mm screw at the rear. For the water filter housing, twist counterclockwise until it disengages, then lift straight up to avoid damaging the O-ring. The main control board is shielded by a metal bracket fastened with three 5mm screws–remove these, then pivot the bracket downward. Label all connectors with masking tape before unplugging to prevent misreassembly. When replacing the defrost heater, ensure the new unit matches the original’s 24-ohm resistance; test with a multimeter before installation.
