OEM Carrier Transformer EAC-1 Series for Model FA4CNB060000AAAA

This OEM Carrier transformer steps down incoming line voltage to the 24V control voltage required to power the thermostat, control board, and relays in the Carrier FA4CNB060000AAAA fan coil unit. Without a functioning transformer, your thermostat goes dark and the entire control circuit loses power, leaving the system unable to call for heating or cooling. A blown transformer is often caused by a shorted wire or a failed component downstream, so inspect the control circuit before installing the replacement. This is a genuine Carrier-spec transformer with the correct primary and secondary voltage ratings and VA capacity for the FA4CNB060000AAAA, ensuring safe and stable control power. Installation is moderate: cut power, label the primary and secondary leads, mount the new transformer, and wire it to match. Most installs take 20-30 minutes and are best done by an HVAC technician. Restoring control power brings the full system back to life. We ship same-day on in-stock orders placed before 3PM CST so you minimize downtime. Choose genuine OEM for dependable performance.

Frequently Asked Questions

Does this Transformer fit my Carrier Model FA4CNB060000AAAA?
Yes. This is the factory-specified OEM transformer for the Carrier Model FA4CNB060000AAAA. 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 FA4CNB060000AAAA?
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.
