Common Questions
What does the LG KNSAP241A pair with?
LG rates KNSAP241A only with KUSAP241A (outdoor unit) or KSSAP241A (system). Other combinations are not AHRI-matched and are not covered by the LG warranty.
What does the KNSAP241A replace?
KNSAP241A is LG's current R32 model in this position and replaces the discontinued LSN243HLV3. R32 and R-410A equipment cannot be mixed — replace the indoor and outdoor unit together.
What power does the KNSAP241A 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 submittal sheet and installation manual available for KNSAP241A?
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 2, 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 KNSAP241A 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.
How fast does this ship?
In-stock items ship the same business day on orders placed before 1pm ET, Monday–Friday. Standard ground delivers to most of the continental US in 2–5 business days.
Does everything ship UPS or FedEx Ground?
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.
