OEM Carrier Control Transformer 40VA 120V/24V for Model N6A48NG480097

This is the OEM factory-specified control transformer (part # HT01BC116) for the Carrier N6A48NG480097 packaged unit. The transformer steps down line voltage from 120V to the 24V required to power the control board, thermostat circuit, and all low-voltage components. When it fails, the entire control circuit goes dead — your thermostat displays nothing or fails to call, and the system will not respond to any inputs. A blown transformer is also often a symptom of a downstream short, so always check for wiring faults before replacing.

• Specs: Input: 120V AC | Output: 24V AC | Rating: 40VA | OEM Part Number: HT01BC116 | Factory-matched for Carrier N6A48NG480097
• OEM vs Generic: This OEM transformer is wound to exact factory specifications, ensuring proper VA capacity and insulation class. Undersized or off-spec generic transformers can overheat, trip their internal breaker repeatedly, or fail prematurely under full low-voltage load.
• Install difficulty: 2/5 — Disconnect power at the breaker before beginning. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter. Photograph all wiring connections before removing the old transformer. Check secondary output (should read 24–28V AC) after installation to confirm correct operation.
• Warranty: 1-year OEM factory warranty against defects in materials and workmanship. In-stock and ships same business day from our warehouse.

Compatibility: Designed specifically for the Carrier N6A48NG480097 packaged unit. Verify input/output voltage and VA rating on your unit's data plate before ordering. If your transformer repeatedly trips or burns out, inspect the 24V control circuit for shorts at the thermostat wiring, zone valves, or control board before installing a new unit.
