OEM Carrier Transformer 60VA 230-24V for Model FF1ANA024011AAAA

This OEM replacement transformer (part# HT01AW230) is the factory-specified control circuit transformer for the Carrier FF1ANA024011AAAA air handler. The transformer steps down line voltage (230V) to the 24V AC signal that powers your thermostat, control board, and all low-voltage components. When this part fails, the entire control circuit goes dark — the thermostat shows no response, the system will not call for heating or cooling, and no error codes will display because the board itself has lost power.

• Specs: 60VA capacity | 230V primary input | 24V secondary output | Factory-matched OEM replacement | Part number HT01AW230
• OEM vs Generic: This OEM transformer is wound to exact factory VA and voltage tolerances. Undersized or off-tolerance generic transformers can overheat, trip the built-in thermal fuse, or deliver unstable 24V output that causes erratic control board behavior and nuisance lockouts.
• Install difficulty: 2/5 — Shut off all power to the air handler before beginning. Tools needed: flathead and Phillips screwdrivers, multimeter, wire nuts or spade connectors. Always verify 0V at the transformer primary leads before touching wiring. Photograph all wiring connections prior to disconnecting.
• Warranty: 1-year OEM factory warranty. In-stock units ship same business day from our warehouse when ordered before 3PM local time.

Compatibility: Designed specifically for the Carrier FF1ANA024011AAAA air handler. Verify your existing transformer's VA rating and primary/secondary voltages on the data plate or unit label before ordering to confirm fitment. If you're unsure, our HVAC parts specialists are available to verify compatibility before you buy — no guesswork required.
