OEM Carrier Furnace Transformer 120V to 24V 40VA for Model UPFLOW080U36M19

The Carrier HT01CN001 is the factory-specified OEM control transformer for the UPFLOW080U36M19 upflow gas furnace. This transformer steps line voltage down from 120V to a 24V control circuit, powering the thermostat, control board, gas valve, and all low-voltage safety circuits. When this transformer fails, the entire control circuit loses power — the thermostat goes dark, the system won't respond to any commands, and you may detect a faint burning smell or hear buzzing from the transformer housing.

Specs: 120V primary | 24V / 12V secondary | 40VA rated | Direct OEM drop-in replacement | Part# HT01CN001 | Replaces legacy part numbers HT01BJ115, 19EA41612, 19EA42612
OEM vs Generic: This is a genuine Carrier factory part. OEM transformers are wound and insulated to exact VA and thermal ratings for the UPFLOW080U36M19 platform. Aftermarket transformers frequently underperform on VA capacity, causing nuisance tripping, premature failure, or unsafe overheating.
Install difficulty: 3/5 — Shut off all power at the breaker before beginning. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter (to verify 24V output post-install), wire labels. Photograph all low-voltage wiring before disconnecting. Confirm incoming line voltage before energizing.
Warranty: 1-year OEM factory warranty. In stock — ships same business day from our warehouse.

Compatibility: Engineered for the Carrier UPFLOW080U36M19 upflow gas furnace. Verify your unit's data plate confirms 120V line input and 24V control circuit before ordering. Cross-reference your existing transformer label against part number HT01CN001 or superseded numbers HT01BJ115 / 19EA41612 / 19EA42612 to confirm fitment. Questions about compatibility? Our HVAC parts specialists verify fitment before you order — reach out before placing your order.

Frequently Asked Questions

Does this Transformer fit my Carrier UPFLOW080U36M19?

Yes. This is the factory-specified OEM transformer for the Carrier UPFLOW080U36M19. 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 UPFLOW080U36M19?

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.
