OEM Carrier Control Transformer 40VA 24V for Model YAC60140YACX302AT

This OEM Carrier transformer (part number P201-35150) is the factory-specified replacement for the Carrier YAC60140YACX302AT packaged/commercial HVAC unit. The control transformer steps line voltage (120V) down to the 24V signal required to power the thermostat, contactors, and all low-voltage control components. When it fails, the entire control circuit goes dead — your thermostat goes blank, relays won't energize, and the system will not respond to any call for heating or cooling.

  • Specs: 120V primary | 24V secondary output | 40VA rated | Class 2 control circuit transformer | OEM part number P201-35150
  • OEM vs Generic: This is a genuine Carrier OEM transformer wound to exact factory VA and voltage tolerances. Generic transformers can run under-rated VA, causing overheating, nuisance trips, and premature control board failure — a much costlier repair.
  • Install difficulty: 2/5 — Shut off all power at the disconnect and breaker before beginning. Tools needed: flathead and Phillips screwdrivers, wire stripper, multimeter to verify 24V output after install. Label all low-voltage wires before disconnecting the old unit.
  • Warranty: 1-year OEM factory warranty. In stock and ships same business day from our warehouse.

Compatibility: Designed and factory-matched for the Carrier YAC60140YACX302AT HVAC system. Always verify your unit's data plate voltage specifications and VA rating before ordering to ensure a correct fitment. Have questions about compatibility? Our HVAC parts specialists verify fitment before you buy — contact us before placing your order.

Frequently Asked Questions

Does this Transformer fit my Carrier YAC60140YACX302AT — P201-35150?
Yes. This is the factory-specified OEM transformer for the Carrier YAC60140YACX302AT — P201-35150. 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 YAC60140YACX302AT — 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.
How fast does National HVAC Parts ship?
