Lg lfxs28968s 00 refrigerator not refrigerating — old house built in 1969

Use only checks that match the exact appliance or system and its official guide.

1. Check 1

   For each of the three refrigerators, photograph the rating label and record the complete model suffix, serial number, market, installation address, room, installation or repair date, and the exact symptom. Confirm whether the affected unit is LG LFXS28968S/00 rather than a visually similar LFXS28968 variant.

   Expected result: All three units have the same exact model and suffix, the units are different models, one unit's identity is uncertain, or the symptom only follows one physical appliance.

   Next step: Use the exact LFXS28968S/00 literature for that unit and keep the other refrigerators as separate comparisons. If the rating label cannot be read safely, stop model-specific troubleshooting and provide the label photo to LG service.

   Stop if: Do not remove panels, move a refrigerator to read a rear label, or order a part from the family name alone.

   Why this matters

   Why: An exact model match permits use of the LFXS28968S support and literature path. Different models or an uncertain suffix make the cross-house pattern a comparison clue, not permission to share settings, codes, or parts. A symptom that follows one appliance is more appliance-specific than a symptom that appears only at one location.

2. Check 2

   With each door opened only briefly, place an appliance thermometer in the center of the refrigerator compartment and the freezer, away from walls, doors, and air outlets. Record the time, displayed settings, measured temperatures, and whether the compressor or fans appear to be operating normally from outside.

   Expected result: The refrigerator is above the recommended 37°F range, the freezer is above the recommended 0°F range, the display and measurements disagree, or the readings are normal after a recent door opening or loading event.

   Next step: Protect temperature-sensitive food and repeat the measurement under normal closed-door use. Use the documented readings to compare the three locations; do not diagnose a compressor or refrigerant problem from temperature alone.

   Stop if: Do not insert a probe through a gasket, remove a sensor, open a service panel, or perform live electrical measurements.

   Why this matters

   Why: Separate compartment measurements distinguish a genuine cooling problem from a display or perception issue. LG says room temperature, loading, blocked vents, and door closure affect cooling, and gives 37°F and 0°F as recommended starting temperatures; a single warm reading after a door opening is not enough to identify a failed part.

3. Check 3

   Measure the ambient temperature beside each refrigerator and inspect the installation from the front and sides without moving the cabinet. Check that the area is dry and ventilated, that the cabinet is not pressed tightly against surrounding surfaces, and that the model manual's clearance requirements are met.

   Expected result: The room is below 55°F or above 110°F, the space is humid or poorly ventilated, the rear or sides lack the required clearance, or all locations meet the documented environmental conditions.

   Next step: Correct only an accessible environmental or clearance problem in accordance with the exact manual, then repeat the compartment measurements. If the room cannot be brought into range or the appliance would need to be moved, use qualified installation or appliance help.

   Stop if: Do not move a heavy refrigerator alone, place it in a damp location, improvise ventilation openings, or use a heater near the appliance.

   Why this matters

   Why: LG says temperatures outside 55°F–110°F can cause excessive cooling or no cooling, and insufficient clearance can prevent heat from the rear cooling motor from dissipating. A repeated environmental or clearance issue can explain a cross-house pattern without proving that every refrigerator has the same internal defect.

4. Check 4

   Check the accessible control display for an off, locked, or unintended setting, then use only the LFXS28968S/00 manual's normal control procedure. LG's general guidance recommends 37°F for the refrigerator and 0°F for the freezer; make one small documented adjustment rather than changing several settings at once.

   Expected result: The display is off or locked, a setting is warmer than the recommended starting point, the controls are correct, or the setting cannot be changed using the normal user interface.

   Next step: Record the original and new setting, then wait through the applicable recovery period before changing anything else. If the controls cannot be changed normally, retrieve the exact manual from the LFXS28968S support page and request service if the interface remains unresponsive.

   Stop if: Do not enter a hidden diagnostic mode, repeatedly cycle power, bypass a lock, or use another LG model's button sequence.

   Why this matters

   Why: A locked or incorrect setting can imitate a cooling failure. LG notes that display appearance and settings vary by model, and that the freezer and refrigerator settings interact on standard designs. A correct setting with persistent warm measurements points back to environment, airflow, door sealing, recovery time, or service—not automatically to a particular component.

5. Check 5

   Inspect shelves, drawer fronts, door bins, and visible air vents without removing panels. Ensure food is not blocking the rear vents, the refrigerator is not packed beyond the manufacturer's airflow guidance, and every door closes fully without a package or shelf pushing it open.

   Expected result: A vent is blocked, the refrigerator is overfilled, a shelf or package prevents full closure, a gasket has a visible gap, or loading and door closure are normal.

   Next step: Rearrange only loose packages, reinstall an obviously misplaced shelf as the manual allows, and close the doors normally. Repeat the temperature check after stabilization; arrange service for a torn gasket, misalignment, or persistent warm readings.

   Stop if: Do not pull out the gasket, adjust hinges, remove air covers, chip ice, reach into a fan, or apply direct heat.

   Why this matters

   Why: LG states that blocked vents interrupt cold-air circulation and that an item preventing full closure lets warm air enter and reduces cooling. If the same loading or closure problem is present at several houses, it is a shared accessible condition; if it is present only on LFXS28968S/00, it is a unit-specific clue but still not a part identification.

6. Check 6

   After the external conditions and one control setting are documented, leave each refrigerator closed and normally loaded while recording temperatures over the recovery period. LG says a recently installed or repaired refrigerator may take two to three days to reach normal operating temperature; use the exact manual if it specifies a different period.

   Expected result: Temperatures return to the recommended range, only refrigerators at one type of location remain warm, the exact LFXS28968S/00 remains warm in an in-range installation, or a safety hazard appears.

   Next step: For persistent warm temperatures, provide LG service the model, serial, measurements, settings, installation comparison, and recovery timeline. Protect or relocate food according to applicable food-safety guidance.

   Stop if: Stop using an appliance with smoke, burning odor, sparking, damaged wiring, water near electrical parts, severe overheating, or unsafe food temperatures; do not open the sealed system or electrical panels.

   Why this matters

   Why: Recovery after installation, loading, or a shared environment points toward an operating condition rather than a confirmed failed part. Persistence in one exact unit after a suitable wait supports a model-specific service decision. Smoke, burning odor, sparks, damaged wiring, water near electrical parts, or unsafe food overrides all further checks.
