What does the KSUJB241A replace?

Is the submittal sheet and installation manual available for KSUJB241A?

Yes — the LG submittal data sheet, engineering manual, installation manual and warranty document are all linked under Documentation on this page and can be downloaded without an account.

Is the stock number on this page real?

Yes — it's the live count from our own shelf, not an availability estimate. If it says 4, that's how many are physically here. When it hits zero, this page says so.

Is this a genuine LG unit, or aftermarket?

Genuine LG OEM equipment — not an aftermarket substitute.

I see this listed under a different name on other sites. Is it the same part?

Yes — manufacturers and distributors sometimes use different brand names or legacy labels for the same part number. Part number KSUJB241A is identical across all name variations.

What's the warranty on this part?

Does everything ship UPS or FedEx Ground?

This part ships by truck freight rather than parcel — still free, included in the price shown, and we'll contact you to schedule delivery before it ships.Most orders ship UPS or FedEx Ground. A small number of large or heavy parts across the catalog ship by truck freight instead — that's still free, and we reach out to arrange a delivery window before those orders leave the warehouse.
