OEM Carrier Furnace Transformer 40VA 120V to 24V — Model UPFLOW200U6020A

This is the factory OEM replacement transformer (part #HT01CN001) for the Carrier UPFLOW200U6020A furnace. The transformer steps down 120V line voltage to a 24V/12V secondary signal that powers your system's entire low-voltage control circuit — including the thermostat, control board, and zone valves. When this transformer fails, the most common symptoms are a completely unresponsive thermostat, a furnace that won't activate on command, or an audible buzzing or humming at the transformer itself. Without a functioning transformer, none of the system's controls can operate.

  • Specs: 120V primary | 24V / 12V dual secondary output | 40VA rated | Factory-matched OEM part #HT01CN001 | Replaces legacy part numbers HT01BJ115, 19EA41612, and 19EA42612
  • OEM vs Generic: This is a genuine Carrier OEM transformer — factory-wound to exact VA and voltage tolerances. Aftermarket transformers frequently run under-rated VA, causing overheating, tripped breakers, and premature control board failure. Do not risk your control board on an undersized generic.
  • Install difficulty: 3/5 — Shut off all power at the breaker and disconnect the 24V wiring harness before removal. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter (to verify 24V output after install). Label all low-voltage wires before disconnecting. If a fuse on the control board has blown, inspect and replace it before powering up the new transformer.
  • Warranty: 1-year OEM factory warranty. In stock and ships same business day from our warehouse.

Compatibility: Designed as a direct OEM drop-in for the Carrier UPFLOW200U6020A furnace. Verify your unit's data plate confirms 120V/60Hz primary input before ordering. Questions about fitment?

Frequently Asked Questions

Does this Transformer fit my Carrier UPFLOW200U6020A?
Yes. This is the factory-specified OEM transformer for the Carrier UPFLOW200U6020A. 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 UPFLOW200U6020A?
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?
