Common Questions
What does the LG KUSXB361A pair with?
LG rates KUSXB361A only with KNSCB361A (indoor unit) or KNUJB361A (indoor unit) or KNSLB361A (indoor unit) or KSSCB361A (system) or KSUJB361A (system) or KSSLB361A (system). Other combinations are not AHRI-matched and are not covered by the LG warranty.
What does the KUSXB361A replace?
KUSXB361A is LG's current R32 model in this position and replaces the discontinued LUU360HV. R32 and R-410A equipment cannot be mixed — replace the indoor and outdoor unit together.
What power does the KUSXB361A need?
208-230V, 1-phase. Minimum circuit ampacity and maximum overcurrent protection are listed in the Specifications table above and on the LG submittal under Documentation; size the breaker and wire to those values and local code.
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 8, 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 KUSXB361A is identical across all name variations.
What's the warranty on this part?
Warranty terms vary by manufacturer. Contact us with your order number for details specific to 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.
