OEM Carrier Transformer 60VA 230-24V for Model FF1ANA024005AAAA

This OEM control circuit transformer is the factory-specified replacement for the Carrier FF1ANA024005AAAA air handler. The transformer steps down 230V line voltage to the 24V signal voltage that powers your thermostat, control board, and all low-voltage switching components. When this transformer fails, the entire control circuit goes dark — your thermostat will appear dead, the system won't respond to any calls for heating or cooling, and no fault codes will display because the board itself has no power. Part number HT01AW230 is the direct OEM replacement built to factory specifications.

• Specs: 60VA rated | Primary voltage: 230V | Secondary voltage: 24V | Factory-matched impedance and thermal protection | OEM Part# HT01AW230
• OEM vs Generic: This OEM transformer meets exact Carrier factory tolerances for VA rating and output voltage stability. Undersized or off-tolerance generic transformers can overload under multi-zone thermostat or communicating control board demands, causing nuisance trips and premature failure.
• Install difficulty: 2/5 — Disconnect power at the disconnect box and verify with a non-contact voltage tester before starting. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter. Photograph all low-voltage wiring connections before removal. Note transformer primary and secondary terminal labeling before disconnecting.
• Warranty: 1-year OEM factory warranty. Ships same business day from our stocked warehouse.

Compatibility: Designed as a direct fit for the Carrier FF1ANA024005AAAA air handler. Confirm your unit's control circuit voltage requirements match 230V primary / 24V secondary and 60VA capacity before ordering. If you're unsure, our HVAC parts specialists can verify fitment using your model and serial number before you buy. Order today and receive same-day shipping on all in-stock parts.
