OEM Carrier 50VA Control Transformer P201-35150 for Model UPFLOW150FAU%14

This is the genuine OEM factory-replacement control transformer for the Carrier UPFLOW150FAU%14 upflow gas furnace. The transformer steps down your home's 120/208/240V line voltage to a safe 12/24VAC signal used by the furnace control board, thermostat, and all low-voltage control circuits. When this transformer fails, the entire control circuit goes dead — symptoms include a blank thermostat display, no response to heat calls, or a furnace that won't initiate any sequence of operation despite power being present at the unit.

  • Specs: 50VA rating | Primary: 120/208/240 VAC | Secondary: 12/24 VAC | 60 Hz | Single phase | CSA listed | OEM Part # P201-35150 (Totaline® Factory Authorized)
  • OEM vs Generic: This is the exact Carrier factory-specified part. Generic transformers often carry lower VA ratings or looser voltage tolerances, risking nuisance tripping of the furnace's 3-amp fuse or premature control board failure. OEM ensures a drop-in fit with no wiring modifications.
  • Install Difficulty: 3/5 — Shut off all power to the furnace before beginning. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter (to verify 24VAC output post-install), wire nuts or spade terminals. Label all low-voltage wires before disconnecting. Verify fuse integrity on the control board after replacement.
  • Warranty: 1-year OEM factory warranty. In-stock and ships same business day from our warehouse.

Compatibility: Engineered specifically for the Carrier UPFLOW150FAU%14 upflow furnace series. Always verify your unit's data plate voltage ratings match the 120/208/240V primary specification before ordering. Not sure if this is the right part?

Frequently Asked Questions

Does this Transformer fit my Carrier UPFLOW150FAU%14?
Yes. This is the factory-specified OEM transformer for the Carrier UPFLOW150FAU%14. 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 UPFLOW150FAU%14?
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?
