OEM Carrier Furnace Transformer 40VA 120V to 24V/12V for Model U19X150U60B

This is the genuine OEM Carrier transformer (part number HT01CN001), the factory-specified control circuit transformer for the Carrier U19X150U60B. The transformer steps down 120V line voltage to a safe 24V (and 12V) output to power the low-voltage control circuit — including your thermostat, relay coils, and control board. When this part fails, the entire control circuit loses power: the thermostat goes dark, the system won't respond to calls for heating or cooling, and you may hear a faint buzz or nothing at all from the unit.

  • Specs: Primary voltage: 120V | Secondary voltage: 12V / 24V | VA rating: 40VA | Factory OEM part number: HT01CN001 | Replaces legacy part numbers HT01BJ115, 19EA41612, 19EA42612
  • OEM vs Generic: This is a genuine Carrier factory part — not an aftermarket substitute. OEM transformers are wound to exact VA and voltage tolerances, protecting downstream components like your control board and thermostat from under- or over-voltage damage that generic units can cause.
  • Install Difficulty: 3/5 — Shut off power at the breaker before beginning. Photograph all low-voltage wiring before disconnecting. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter (to verify 24V output after installation). If the transformer has blown a fuse, inspect control wiring for shorts before powering up the replacement.
  • Warranty: 1-year OEM factory warranty. Ships same business day from our warehouse — order before 3 PM local time.

Compatibility: Engineered for the Carrier U19X150U60B. Verify your unit's data plate voltage and VA requirements before ordering — substituting incorrect VA-rated transformers can damage control boards. Our parts specialists are available to confirm fitment before you buy. Order today and get your system back online fast.

Frequently Asked Questions

Does this Transformer fit my Carrier U19X150U60B?
Yes. This is the factory-specified OEM transformer for the Carrier U19X150U60B. 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 U19X150U60B?
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?
