OEM Carrier Transformer 60VA 230-24V for Model FD3ANA030006AAAA

This OEM control circuit transformer (part# HT01AW230) is the factory-specified replacement for the Carrier FD3ANA030006AAAA fan coil unit. The transformer steps down 230V line voltage to the 24V AC signal that powers your thermostat, control board, zone valves, and all low-voltage safety circuits. When this transformer fails, the entire control circuit goes dead — your thermostat goes blank, the system won't respond to any calls for heating or cooling, and no error codes will appear because the board itself has no power.

• Specs: 60VA output capacity | 230V primary input | 24V secondary output | OEM part number HT01AW230 | Factory-matched winding and core specifications for reliable long-term operation
• OEM vs Generic: OEM transformers are wound to exact VA and voltage tolerances required by the Carrier FD3ANA030006AAAA control board. Undersized or off-tolerance generic transformers can overheat, trip thermal cutoffs, and damage downstream control boards — costing far more than the transformer itself.
• Install difficulty: 2/5 — Shut off all power at the disconnect and breaker before beginning. Tools needed: flathead and Phillips screwdrivers, wire stripper, multimeter, and wire nuts. Photograph all existing low-voltage wiring connections before removing the old unit. Verify 24V output with a multimeter before closing the panel.
• Warranty: 1-year OEM factory warranty against defects in materials and workmanship. In-stock and ships same business day from our warehouse.

Compatibility: Engineered specifically for the Carrier FD3ANA030006AAAA fan coil unit. Confirm your unit's data plate shows a 230V primary input requirement before ordering — some similar fan coil variants use a 120V primary transformer. If you have any fitment questions, our HVAC parts specialists are available to verify compatibility before you buy. Order today and receive same-day shipping on all in-stock parts.
