OEM Carrier 50VA Control Transformer (P201-35150) for Model UPFLOW080FAUS12A

This OEM step-down transformer is the factory-specified replacement for the Carrier UPFLOW080FAUS12A upflow gas furnace. The transformer converts incoming line voltage (120/208/240 VAC) down to a safe 12/24 VAC used to power the system's control board, thermostat circuit, and all low-voltage control components. When this transformer fails, the result is typically a completely unresponsive furnace — no thermostat communication, no ignition sequence, and no blower activity. If your system is totally dead despite confirmed line power, a failed transformer is one of the first components to test.

  • Specs: 50VA rated | Primary voltage: 120/208/240 VAC | Secondary voltage: 12/24 VAC | Single phase | 60 Hz | CSA listed | OEM part number: P201-35150
  • OEM vs Generic: This is a genuine OEM Carrier/Totaline unit built to exact factory VA and voltage tolerances. Generic transformers often run under-rated VA capacity, leading to overheating and premature failure — especially in multi-stage furnace control circuits.
  • Install difficulty: 2/5 — Shut off all power to the unit before beginning. Tools needed: flathead and Phillips screwdrivers, wire stripper, multimeter. Photograph all low-voltage wiring connections before disconnecting. Match primary tap to your supply voltage. Typical job time: 30–45 minutes.
  • Warranty: 1-year OEM factory warranty. In stock and ships same business day from our warehouse.

Compatibility: Designed for the Carrier UPFLOW080FAUS12A upflow gas furnace. Always verify your supply voltage (120V or 208/240V) to confirm the correct primary tap before installation. Compatible with standard 24V thermostat and control board wiring. Questions about fitment? Our HVAC parts specialists verify compatibility before you order — contact us anytime.

Frequently Asked Questions

Does this Transformer fit my Carrier UPFLOW080FAUS12A?
Yes. This is the factory-specified OEM transformer for the Carrier UPFLOW080FAUS12A. 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 UPFLOW080FAUS12A?
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?
