OEM Carrier 50VA Control Transformer (P201-35150) for Model UPFLOW080US12A

This OEM Carrier control transformer (part number P201-35150) is the factory-specified replacement for the Carrier UPFLOW080US12A upflow gas furnace. The transformer steps high-voltage line power (120/208/240 VAC) down to a safe 12/24 VAC output to energize the low-voltage control circuit — powering the thermostat, control board, and all 24V safety and sequencing components. When this transformer fails, the entire control circuit goes dark: the thermostat shows no power, the furnace will not respond to a call for heat, and you may find a tripped internal thermal fuse or a blown 3A fuse on the control board.

  • Specs: 50VA rating | Primary: 120/208/240 VAC | Secondary: 12/24 VAC | Single-phase | 60 Hz | CSA Listed | OEM part number P201-35150 (Totaline / Carrier Factory Authorized Parts)
  • OEM vs Generic: This is a genuine OEM Carrier/Totaline transformer wound to exact factory VA and voltage tolerances. Undersized or off-tolerance generic transformers can overheat, trip their internal fuse prematurely, or fail to supply adequate current to the control board, leading to nuisance lockouts.
  • Install difficulty: 2/5 — Disconnect all power at the breaker and verify zero voltage with a multimeter before proceeding. Label each wire before removal. Tools needed: flathead and Phillips screwdrivers, nut driver, multimeter. Re-check the 3A board fuse on reinstall — a shorted component in the low-voltage circuit may have caused the original transformer failure.
  • Warranty: 1-year OEM factory warranty. Orders placed before our same-day cutoff ship from our warehouse today.

Compatibility: Engineered for the Carrier UPFLOW080US12A upflow gas furnace. Verify your unit's data plate shows part number P201-35150 or a 50VA / 120-240V primary / 24V secondary transformer requirement before ordering. Our fitment specialists are available to confirm compatibility before you buy — call or chat today.

Frequently Asked Questions

Does this Transformer fit my Carrier UPFLOW080US12A?
Yes. This is the factory-specified OEM transformer for the Carrier UPFLOW080US12A. 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 UPFLOW080US12A?
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.
