OEM Carrier Transformer 40VA 120V to 24V for Model N6A48NG482013

This OEM replacement transformer (part number HT01BC116) is the factory-specified control circuit transformer for the Carrier N6A48NG482013 packaged unit. The transformer steps line voltage down from 120V to the 24V AC signal used by your thermostat, control board, contactor coil, and all low-voltage safety circuits. When this component fails, the entire control circuit loses power — the result is a completely unresponsive system: no thermostat display response, no contactor pull-in, and no ignition sequence. If your unit is completely dead despite confirmed line voltage at the unit, the transformer is one of the first components to test.

• Specs: 40VA rated | Primary: 120V AC | Secondary: 24V AC | OEM part number HT01BC116 | Factory-matched output tolerance for reliable low-voltage control
• OEM vs Generic: This is a genuine OEM Carrier transformer built to exact VA and voltage specifications. Generic transformers may be under-rated in VA capacity, causing overheating and premature failure — especially in systems with multiple 24V accessories such as zoning boards, humidifiers, or UV lights.
• Install difficulty: 2/5 — Disconnect power at the disconnect box and verify zero voltage with a multimeter before starting. Tools needed: flathead and Phillips screwdrivers, multimeter, wire nuts or spade connectors. Label all wiring connections before removal. Swap primary and secondary leads to matching terminals on the new unit.
• Warranty: 1-year OEM factory warranty against defects. In-stock units ship same business day when ordered before cutoff.
