OEM Carrier Transformer 50VA 120/240-24V — P201-35150 for Model YAC2480YACX506C

This is the factory OEM step-down transformer for the Carrier YAC2480YACX506C, sold under Carrier part number P201-35150. The transformer converts incoming line voltage (120/208/240 VAC) down to 12/24 VAC to power your system's control board, thermostat, and all low-voltage control circuits. When this transformer fails, the entire control circuit loses power — symptoms include a completely unresponsive thermostat, a system that won't energize at all, or a blown fuse on the control board that keeps returning. Replacing the transformer with the exact OEM unit restores factory-spec voltage regulation and protects every downstream component.

  • Specs: 50VA rating | Primary voltage: 120/208/240 VAC | Secondary voltage: 12/24 VAC | 60 Hz | Single phase | CSA listed | Factory part number P201-35150
  • OEM vs Generic: This is a genuine Carrier/Totaline factory-authorized transformer, matched precisely to the VA load and winding spec of the YAC2480YACX506C. Off-brand units often underperform on VA capacity, causing nuisance fuse trips and premature control board failure.
  • Install difficulty: 3/5 — Turn off all power at the disconnect and breaker before beginning. Tools needed: multimeter, flathead and Phillips screwdrivers, wire stripper, needle-nose pliers. Label and photograph all wiring connections before disconnecting. Verify 24V output with a multimeter after installation before closing the panel.
  • Warranty: 1-year OEM factory warranty. In stock and ships same business day from our warehouse.

Compatibility: Designed for Carrier model YAC2480YACX506C. Cross-references Totaline P201-35150. Verify your unit's primary voltage (120V or 240V) and VA demand on the equipment data plate before ordering. Our fitment team is available to confirm compatibility before you buy — no guesswork required.

Frequently Asked Questions

Does this Transformer fit my Carrier YAC2480YACX506C?
Yes. This is the factory-specified OEM transformer for the Carrier YAC2480YACX506C. 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 YAC2480YACX506C?
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?
