OEM Carrier 50VA Transformer 120/240-24V for Model UPFLOW180FAUHAC14

This OEM control transformer (part# P201-35150) is the factory-specified replacement for the Carrier UPFLOW180FAUHAC14 upflow furnace. The transformer steps down your home's 120/208/240V line voltage to a safe 12/24V for the low-voltage control circuit — powering the thermostat, control board, and all 24V accessories. When this part fails, the entire control circuit goes dark: the thermostat goes blank, the furnace refuses to start, or the system may blow the 3A control fuse repeatedly.

  • Specs: 50 VA rating | Primary: 120/208/240 VAC | Secondary: 12/24 VAC | 60 Hz | Single phase | CSA Listed | Round case with multi-mount bracket
  • OEM vs Generic: This is a genuine Carrier/Totaline factory part, wound to exact VA and impedance specs. Generic transformers often run under-rated VA, causing overheating and nuisance fuse failures on high-demand control circuits.
  • Install difficulty: 2/5 — Shut off power at the breaker before starting. Tools needed: flathead and Phillips screwdriver, needle-nose pliers, multimeter. Note wire colors and spade terminal positions before disconnecting. The transformer mounts to the furnace cabinet with two screws.
  • Warranty: 1-year OEM factory warranty. Ships same business day from our warehouse.

Compatibility: Designed for the Carrier UPFLOW180FAUHAC14 upflow gas furnace. Verify the primary voltage (120V or 240V) and VA rating on your unit's wiring diagram or data plate before ordering. For fitment questions, our HVAC-certified team is available to confirm compatibility before you buy.

Frequently Asked Questions

Does this Transformer fit my Carrier UPFLOW180FAUHAC14?
Yes. This is the factory-specified OEM transformer for the Carrier UPFLOW180FAUHAC14. 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 UPFLOW180FAUHAC14?
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?
