OEM Carrier 50VA Control Transformer P201-35150 for Model YAC60140YAC102AT

This OEM step-down transformer is the factory-specified replacement for the Carrier YAC60140YAC102AT unit, sold under OEM part number P201-35150 (also cross-referenced as Totaline P201-35150). The transformer converts high-voltage line power — 120, 208, or 240 VAC — down to a safe 24V AC output that powers your system's control board, thermostat, and all low-voltage control circuits. When this part fails, the entire 24V control circuit goes dead: the thermostat goes blank, the system won't respond to any call for heating or cooling, and in some cases a blown fuse or tripped breaker on the secondary side is the first clue. Replacing it with the correct OEM unit restores factory-matched performance and protects downstream components from voltage irregularities.

  • Specs: 50 VA rating | Primary: 120 / 208 / 240 VAC multi-tap | Secondary: 12 / 24 VAC | 60 Hz | Single phase | CSA listed | Dimensions: 3.8" L × 3.1" W × 2.2" H
  • OEM vs Generic: The OEM P201-35150 is manufactured to Carrier's exact VA rating and insulation class. Generic transformers often carry ±10–15% VA tolerance, increasing the risk of overheating under full control-circuit load — a leading cause of repeat transformer failure.
  • Install difficulty: 3/5 — Turn off power at the breaker AND disconnect panel before beginning. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter (to confirm 0V before touching terminals and 24V output after). Label or photograph all wiring connections before removing the old transformer. Mount style and terminal locations match factory configuration exactly.
  • Warranty: 1-year OEM factory warranty. In stock and ships same business day from our warehouse.

Compatibility: Direct OEM replacement for Carrier model YAC60140YAC102AT. Also cross-references to Totaline P201-35150 and part number HCTY156D0LS11102. Confirm your unit's data plate shows a 50VA, 120/208/240-12/24V transformer requirement before ordering. Have a fitment question?

How do I replace the transformer on my Carrier OEM Carrier Transformer 50VA 120/208/240-24V — P201-35150?
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.
