OEM Carrier Transformer 60VA 230-24V for Model FD3ANA018005AAAA

This OEM control circuit transformer is the factory-specified replacement for the Carrier FD3ANA018005AAAA fan coil unit. The transformer steps down 230V line voltage to the 24V signal used by your thermostat, control board, and all low-voltage safety circuits. When this component fails, the entire control circuit goes dark — your thermostat goes blank, the system won't respond to any calls for heating or cooling, and nothing turns on. Part number HT01AW230 ensures a direct factory fit with no modifications required.

  • Specs: 60VA rating | 230V primary input | 24V secondary output | Factory-matched OEM tolerances for stable, reliable low-voltage control power
  • OEM vs Generic: OEM transformers are wound and tested to Carrier's exact VA and voltage specifications. Undersized or off-tolerance generic transformers can overheat, trip internal fuses, or damage downstream control boards — making OEM the clear choice for long-term reliability.
  • Install difficulty: 2/5 — Disconnect all power to the unit before beginning. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter. Verify 24V output at secondary terminals before restoring system power. Photograph all wiring connections prior to removal.
  • Warranty: 1-year OEM factory warranty. In-stock and ships same business day from our warehouse.

Compatibility: Designed specifically for the Carrier FD3ANA018005AAAA fan coil unit. Always verify your unit's data plate voltage requirements match 230V primary / 24V secondary before ordering. Our parts specialists are available to confirm fitment — order with confidence.

Frequently Asked Questions

Does this Transformer fit my Carrier FD3ANA018005AAAA?
Yes. This is the factory-specified OEM transformer for the Carrier FD3ANA018005AAAA. It is a direct drop-in replacement that fits without modification. Always verify the model number on your equipment nameplate before ordering.
How do I replace the transformer on my Carrier FD3ANA018005AAAA?
Difficulty: Medium (30–45 min)
Step 1: Turn off breaker. Step 2: Photo wiring connections. Step 3: Disconnect wires from old transformer. Step 4: Remove mounting hardware. Step 5: Install new transformer, reconnect wires matching voltage ratings. Step 6: Verify 24V output with multimeter.
My thermostat has no power. What failed?
Thermostat with no display = failed 24V transformer (or blown control board fuse). Check the 3A/5A fuse on the control board first ($1–$5 fix). If fuse is good but no 24V output from transformer, replace transformer.
Is this transformer compatible with Bryant or Payne too?
Many Carrier parts are cross-compatible with Bryant and Payne since all three brands are manufactured by Carrier Global Corporation. The same physical part is often used across brand labels with different model numbers. To verify: check your Bryant or Payne equipment service manual for cross-compatible part numbers, or email info@nationalhvacparts.com with your model number.
Should I use OEM or aftermarket for my Carrier transformer?
OEM recommended for reliability and warranty compatibility. OEM parts match exact factory specifications for proper fit, performance, and safety. While aftermarket alternatives cost less upfront, the risk of improper fit and reduced lifespan usually makes OEM the better value long-term.
