OEM Carrier Transformer EAC-101 Series for Model FB4BNF060000AAAA

This genuine Carrier transformer converts line voltage into the 24V control power that operates the thermostat, relays, and control board on your FB4BNF060000AAAA fan coil unit. When the transformer burns out, you lose all low-voltage control: the thermostat goes blank, the blower won't respond, and the unit seems dead despite having line power. Wound to exact Carrier primary and secondary specifications, this transformer restores reliable 24V control power to your FB4BNF060000AAAA. Installation is moderate and takes roughly 20-30 minutes: disconnect power at the breaker, photograph the primary and secondary wiring, transfer the leads to matching terminals, and verify the VA rating matches the original. The correct OEM transformer ensures proper voltage and amperage for your control circuit, preventing the blown fuses and nuisance trips common with mismatched generics. In stock and ships same-day on orders before 3PM CST. National HVAC Parts is your trusted source for genuine Carrier transformers and rapid shipping.

Frequently Asked Questions

Does this Transformer fit my Carrier Model FB4BNF060000AAAA?
Yes. This is the factory-specified OEM transformer for the Carrier Model FB4BNF060000AAAA. 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 Model FB4BNF060000AAAA?
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.
How fast does National HVAC Parts ship?
