OEM Carrier 40VA Control Transformer P201-35150 for Model UPFLOW070US12A

This OEM control transformer (part number P201-35150) is the factory-specified replacement for the Carrier UPFLOW070US12A upflow gas furnace. The transformer steps down 120V line voltage to 24V AC to power the low-voltage control circuit — including the thermostat, control board, gas valve, and ignition system. When this transformer fails, the entire control circuit goes dark: the thermostat shows no power, the furnace won't respond to any call for heat or cooling, and in some cases a tripped or blown 3A fuse on the board is the first clue.

  • Specs: 120V primary → 24V secondary | 40VA output rating | Factory-matched OEM replacement | Plug-and-play terminal connections for Carrier UPFLOW070US12A wiring harness
  • OEM vs Generic: OEM transformers are wound to exact VA and voltage tolerance specifications. Undersized or off-spec generic transformers can overheat, blow fuses, and stress downstream components like the gas valve solenoid and control board.
  • Install difficulty: 2/5 — Always disconnect 120V power at the breaker before servicing. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter (to verify 24V output after install). Photograph all wiring connections before removal.
  • Warranty: 1-year OEM factory warranty. Ships same business day from our warehouse when ordered before cutoff.

Compatibility: Designed specifically for the Carrier UPFLOW070US12A upflow gas furnace. Verify transformer VA rating and primary/secondary voltages on your unit's data plate or wiring diagram before ordering. Our HVAC parts specialists are available to confirm fitment — contact us before you order if you have any questions.

Frequently Asked Questions

Does this Transformer fit my Carrier UPFLOW070US12A?
Yes. This is the factory-specified OEM transformer for the Carrier UPFLOW070US12A. 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 UPFLOW070US12A?
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?
