OEM Carrier 50VA Control Transformer P201-35150 for Model UPFLOW180FAU14A

This is the factory OEM replacement control transformer for the Carrier UPFLOW180FAU14A upflow gas furnace. The transformer steps down incoming line voltage (120/208/240 VAC) to a safe 24V AC signal that powers your system's control board, thermostat, and all low-voltage control circuits. When this transformer fails, the entire control circuit loses power — resulting in a completely unresponsive thermostat, a furnace that won't start, or a system that shows no activity whatsoever despite power being present at the unit.

  • Specs: 50VA rating | Primary: 120/208/240 VAC | Secondary: 12/24V AC | 60 Hz | Single-phase | CSA listed | OEM Part # P201-35150
  • OEM vs Generic: This is a genuine Carrier/Totaline factory-authorized part. OEM transformers are wound and insulated to exact VA tolerances, preventing nuisance tripping and premature failure of downstream control boards. Generic alternatives may run outside VA tolerance, risking damage to your IFC board.
  • Install difficulty: 2/5 — Shut off all power at the breaker AND the unit disconnect before beginning. Tools needed: flathead and Phillips screwdrivers, wire stripper, multimeter. Always label existing wiring before disconnecting. Verify 24V output with a multimeter after installation before restoring full system power.
  • Warranty: 1-year OEM manufacturer warranty. In-stock and ships same business day from our warehouse.

Compatibility: Engineered specifically for the Carrier UPFLOW180FAU14A upflow furnace. Verify the part number on your existing transformer's label before ordering — primary and secondary voltage ratings must match your unit's wiring diagram. Have questions about fitment? Our HVAC parts specialists verify compatibility before you buy — contact us today and get your furnace back online fast.

Frequently Asked Questions

Does this Transformer fit my Carrier UPFLOW180FAU14A?
Yes. This is the factory-specified OEM transformer for the Carrier UPFLOW180FAU14A. 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 UPFLOW180FAU14A?
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?
