OEM Carrier Transformer 60VA 230-24V for Model FF1ANA030002AAAA

This OEM step-down transformer (part number HT01AW230) is the factory-specified replacement for the Carrier FF1ANA030002AAAA air handler. It converts 230V line voltage down to the 24V AC signal that powers your thermostat, control board, and all low-voltage safety circuits. When this transformer fails, the entire control circuit goes dark — your thermostat goes blank, the system won't respond to any calls for heating or cooling, and you may notice a burning smell or a tripped fuse on the control board.

• Specs: 60VA rating | 230V primary input | 24V secondary output | OEM part number HT01AW230 | Factory-matched voltage and VA capacity for safe, reliable operation
• OEM vs Generic: This OEM transformer is wound to exact Carrier factory specifications. Generic alternatives often carry lower VA ratings or looser voltage tolerances, risking nuisance tripping, control board damage, or premature failure under full load.
• Install difficulty: 2/5 — Shut off all power at the breaker before beginning. Tools needed: flathead and Phillips screwdrivers, multimeter, wire stripper, and needle-nose pliers. Label or photograph all low-voltage wiring connections before disconnecting. Verify fuse condition on the control board before energizing.
• Warranty: 1-year OEM factory warranty. Ships same business day from our stocked warehouse.

Compatibility: Engineered for the Carrier FF1ANA030002AAAA air handler. Confirm your existing transformer's VA rating and primary/secondary voltages on the unit data plate or wiring diagram before ordering. A 60VA transformer supports higher accessory loads than a standard 40VA unit — do not substitute a lower-rated transformer. Our parts specialists are available to verify fitment before you order.
