ADQ75493310
Original slanted cover in the affected bulletin.
LG says the standardization issue can prevent the LT120F filter from fitting and directs replacement with the new cover.
Evidence note C076 · United States
LG published a narrow service bulletin for refrigerators whose LT120F filter will not fit the original slanted cover. The model and serial range are part of the answer.
Direct answer
LG’s 2023-08-31 service bulletin changes air-filter cover ADQ75493310 to ADQ75493321 and adds ADQ73214408 as the separate LT120F filter. The bulletin is limited to nine named refrigerator models in serial range 206KR*–306KR* (June 2022–June 2023). LG also operates a part-request portal for those nine models when a new LT120F will not fit.
Decision map
Family resemblance is not compatibility evidence. Each row stops exactly where the cited source stops.
Original slanted cover in the affected bulletin.
LG says the standardization issue can prevent the LT120F filter from fitting and directs replacement with the new cover.
New square cover for the bulletin’s exact model/serial scope.
LG lists it as the changed 631A air-filter cover assembly.
Separate LT120F filter, not the cover.
LG lists it as newly added location 631C and labels it “Filter only (LT120F).”
Do not generalize the bulletin.
The part change is tied to nine sales models and serial range 206KR*–306KR*. Use LG model-specific support outside that scope.
Before buying
Confirm the refrigerator model is one of: LRYXC2606D, LRYXC2606S, LRYKC2606S, LCFC26XSS, LRFOC2606S, LRFXC2606S, LRFGC2706S, LLFGC2706S or LRFLC2706S.
Confirm the serial falls within LG’s 206KR*–306KR* bulletin range and that the symptom is an LT120F filter that will not fit the slanted cover.
Use LG’s Air Filter Part Request portal before purchasing a third-party assembly; it asks for the exact model and serial.
Keep the two identifiers separate: ADQ75493321 is the cover assembly; ADQ73214408 is the LT120F filter.
Primary evidence
Evidence boundary
This note applies only to the model, suffix/serial and symptom scope printed by LG. The bulletin is intended for experienced technicians and says information may change. This page does not certify third-party parts or instruct a refrigerator repair beyond identifying the published replacement path.
