OEM Carrier Transformer ET4006 for Model FA4CNC060010AAAA

This OEM Carrier transformer (ET4006-style) converts incoming line voltage to the 24V control power that runs the thermostat, relays, and control board in your FA4CNC060010AAAA fan coil. A dark thermostat or complete loss of control function frequently traces back to a blown transformer. Manufactured to exact Carrier VA and voltage specifications, it provides stable low-voltage power for reliable system operation. This is a direct-fit replacement for the FA4CNC060010AAAA, with matching primary and secondary leads for a straightforward swap. Installation is moderate, around 20-30 minutes: shut off power at the breaker, label and transfer the wiring, and mount to the existing bracket. Because a failed transformer often points to a short in the control circuit, inspect downstream wiring before re-energizing. Genuine OEM ensures the correct rating and dependable longevity over aftermarket substitutes. We stock this part and ship same-day on orders placed before 3PM CST, getting your HVAC system back online quickly. Our team is available to help confirm fitment.

Frequently Asked Questions

Does this Transformer fit my Carrier Model FA4CNC060010AAAA?
Yes. This is the factory-specified OEM transformer for the Carrier Model FA4CNC060010AAAA. 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 FA4CNC060010AAAA?
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?
