OEM Carrier Transformer 60VA 230-24V for Model FF1ANA018075AAAA

This OEM control circuit transformer (part# HT01AW230) is the factory-specified replacement for the Carrier FF1ANA018075AAAA air handler. The transformer steps down 230V line voltage to the 24V AC signal that powers your thermostat, control board, and all low-voltage switching components. When this transformer fails, the entire control circuit goes dark — the thermostat loses power, the system stops responding to calls for heating or cooling, and nothing operates. If you have 230V at the unit but zero voltage at the 24V secondary terminals, a failed transformer is the most common cause.

• Specs: 60VA rated | 230V primary input | 24V secondary output | Factory-matched OEM tolerances | Part number HT01AW230
• OEM vs Generic: This is the factory OEM unit — wound to exact VA and voltage specifications for the FF1ANA018075AAAA air handler. Generic transformers rated at lower VA can brown out under full control circuit load, causing intermittent faults and nuisance lockouts.
• Install difficulty: 2/5 — Shut off power at the breaker and verify zero voltage with a multimeter before touching any wiring. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter. Label or photograph all low-voltage wire connections before disconnecting. Reconnect secondary (24V) wires first, then primary (230V) last.
• Warranty: 1-year OEM factory warranty against defects. Ships same business day from our stocked warehouse.

Compatibility: Designed and factory-specified for the Carrier FF1ANA018075AAAA air handler. Always verify primary voltage (230V) and VA rating on your unit's data plate before ordering to confirm correct fitment. Our parts specialists are available to verify compatibility before you buy — orders placed before 3 PM ship the same business day.
