OEM Carrier Control Transformer 50VA 120/208/240V–12/24V for Model YAC60140YAC301C

This OEM step-down transformer (Part # P201-35150) is the factory-specified replacement for the Carrier YAC60140YAC301C HVAC unit. The transformer converts incoming line voltage (120/208/240 VAC) down to 12/24 VAC to power the system's control board, thermostat, and all low-voltage control circuits. When it fails, the entire control circuit loses power — resulting in a completely unresponsive thermostat, a system that won't start, or tripped low-voltage fuses that keep blowing without an obvious cause.

  • Specs: 50 VA rating | Primary: 120/208/240 VAC | Secondary: 12/24 VAC | 60 Hz | Single-phase | CSA listed | Dimensions: 3.8" L × 3.1" W × 2.2" H
  • OEM vs Generic: This is a genuine Carrier/Totaline factory-authorized part (P201-35150), engineered to exact VA and voltage tolerances. Off-brand transformers often underperform under full load, causing nuisance trips and premature control board failure.
  • Install difficulty: 3/5 — Shut off all power at the breaker and disconnect the load before servicing. Tools needed: flathead and Phillips screwdrivers, multimeter, wire labels or tape. Photograph all wiring before disconnecting terminals. Verify primary voltage tap matches your supply voltage before energizing.
  • Warranty: 1-year OEM factory warranty. In stock — ships same business day from our warehouse.

Compatibility: Engineered for Carrier model YAC60140YAC301C. Confirm your unit's supply voltage (120V or 208/240V) and verify part number P201-35150 against the data plate or wiring diagram before ordering. Need fitment help? Our HVAC parts specialists verify compatibility before you buy — order with confidence.

Frequently Asked Questions

Does this Transformer fit my Carrier YAC60140YAC301C?
Yes. This is the factory-specified OEM transformer for the Carrier YAC60140YAC301C. 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 YAC60140YAC301C?
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?
