OEM Carrier 40VA Control Transformer HT01CN001 for Model UPFLOW080FAUAC14B

This OEM step-down transformer is the factory-specified replacement for the Carrier UPFLOW080FAUAC14B upflow gas furnace. The transformer converts 120V line voltage to 24V AC to power the entire low-voltage control circuit — including the thermostat, gas valve, inducer relay, and control board. When it fails, the system goes completely unresponsive: no thermostat display, no blower activity, and no ignition attempt. A failed transformer is one of the most overlooked root causes of a furnace that appears completely dead.

  • Specs: 40VA rated | 120V primary / 24V secondary | Factory-matched footprint and terminal configuration for direct OEM fit | Part Number: HT01CN001
  • OEM vs Generic: This is a genuine Carrier OEM transformer built to exact VA and impedance specifications. Generic transformers often underperform at rated VA, causing nuisance tripping of the onboard thermal fuse and premature control board failure.
  • Install Difficulty: 2/5 — Shut off all power at the breaker before starting. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter (to confirm 24V output after installation). Label all low-voltage wire connections before disconnecting the old unit.
  • Warranty: 1-year OEM factory warranty. Orders ship same business day from our warehouse when placed before cutoff.

Compatibility: Designed for the Carrier UPFLOW080FAUAC14B upflow gas furnace. Verify your unit's data plate matches the 120V/24V 40VA transformer specification before ordering. Our fitment team is available to confirm compatibility — just reach out before you order and we'll verify it for you.

Frequently Asked Questions

Does this Transformer fit my Carrier UPFLOW080FAUAC14B?
Yes. This is the factory-specified OEM transformer for the Carrier UPFLOW080FAUAC14B. 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 UPFLOW080FAUAC14B?
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?
