OEM Carrier 50VA Control Transformer P201-35150 for Model UPFLOW180UAHAC14A

This is the genuine OEM replacement control circuit transformer for the Carrier UPFLOW180UAHAC14A upflow air handler. The transformer steps down the incoming line voltage — 120, 208, or 240 VAC — to a safe 24VAC output that powers your system's control board, thermostat, and all low-voltage control circuits. When this transformer fails, the entire control circuit goes dark: the thermostat goes blank, the system locks out, and no heating or cooling function responds. Replacing it with the correct OEM unit restores full control circuit integrity immediately.

  • Specs: 50VA rating | Primary: 120/208/240 VAC multi-tap | Secondary: 12/24 VAC | 60 Hz single-phase | CSA listed | Factory part number P201-35150
  • OEM vs Generic: This is the factory-authorized Carrier/Totaline unit — wound to exact VA and voltage tolerances. Generic transformers frequently run at lower VA ratings or use inferior core materials, risking premature burnout and control board damage from voltage fluctuation.
  • Install difficulty: 2/5 — Shut off all power to the unit at the breaker before starting. Tools needed: flathead and Phillips screwdrivers, wire stripper, multimeter. Label all low-voltage wires before disconnecting. Verify primary tap selection matches your supply voltage before energizing.
  • Warranty: 1-year OEM factory warranty. In stock and ships same business day from our warehouse.

Compatibility: Engineered as a direct OEM replacement for the Carrier UPFLOW180UAHAC14A upflow air handler. Verify your unit's supply voltage (120V, 208V, or 240V) to confirm correct primary tap selection before installation. Questions about fitment? Our HVAC parts specialists verify compatibility before you order — ships same day.

Frequently Asked Questions

Does this Transformer fit my Carrier UPFLOW180UAHAC14A?
Yes. This is the factory-specified OEM transformer for the Carrier UPFLOW180UAHAC14A. 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 UPFLOW180UAHAC14A?
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?
