OEM Carrier 50VA Control Circuit Transformer P201-35150 for Model UPFLOW180UA14A

This is the genuine OEM Carrier replacement transformer (part number P201-35150) factory-specified for the Carrier UPFLOW180UA14A upflow gas furnace. The transformer steps down high-voltage line power (120/208/240 VAC) to the safe low-voltage signal (12/24V) that energizes your control board, thermostat, and all 24V accessory circuits. When this transformer fails, the result is immediate and total: the thermostat goes dark, the furnace won't respond to any call for heat or cooling, and the control board loses all power. A failed transformer is often misdiagnosed as a board failure — always test the transformer first.

  • Specs: 50VA rating | Primary: 120/208/240 VAC | Secondary: 12/24 VAC | 60 Hz | Single-phase | CSA listed | Totaline/Carrier factory part
  • OEM vs Generic: This OEM unit is wound to exact Carrier factory tolerances, ensuring a stable 24V output that won't under-drive the control board or overheat under peak load. Generic transformers with loose VA tolerances can cause intermittent lockouts and nuisance tripped breakers.
  • Install difficulty: 2/5 — Shut off power at the disconnect and breaker before beginning. Tools needed: flathead and Phillips screwdrivers, multimeter, wire nuts or spade connectors. Label all low-voltage wires before disconnecting. Verify incoming voltage tap matches your supply voltage.
  • Warranty: 1-year OEM factory warranty. In-stock and ships same business day from our warehouse.

Compatibility: Direct OEM replacement for Carrier UPFLOW180UA14A upflow furnaces. Cross-references Totaline part number P201-35150. Verify your unit's data plate voltage requirements (120V or 208/240V) and confirm you select the correct primary voltage tap on installation. Questions about fitment? Our HVAC parts specialists verify compatibility before you order — reach out before purchasing.

Frequently Asked Questions

Does this Transformer fit my Carrier UPFLOW180UA14A?
Yes. This is the factory-specified OEM transformer for the Carrier UPFLOW180UA14A. 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 UPFLOW180UA14A?
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?
