OEM Carrier 40VA Control Transformer for Model YAC2480YAC506C — P201-35150

This OEM control transformer (part number P201-35150) is the factory-specified replacement for the Carrier YAC2480YAC506C packaged unit. The transformer steps down 120V line voltage to the 24V signal voltage that powers the entire control circuit — including the thermostat, contactor coil, and control board. When it fails, nothing in the system responds: the thermostat goes dead, relays won't energize, and the unit won't start at any stage. It is often the first component to check when the entire low-voltage control circuit goes silent.

  • Specs: 40VA rating | Primary: 120V | Secondary: 24V | OEM part number P201-35150 | Direct factory replacement with exact terminal and mounting configuration
  • OEM vs Generic: OEM transformers are wound to exact VA and voltage tolerances for the Carrier YAC2480YAC506C. Undersized or off-tolerance generic units can overheat, trip the thermal cutoff, or cause erratic control board behavior — problems that are easy to misdiagnose as a bad board.
  • Install difficulty: 2/5 — Shut off all power before proceeding. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter (verify 24V output after install). Photograph all wiring connections before disconnecting. The transformer mounts to the control panel bracket with standard fasteners.
  • Warranty: 1-year OEM factory warranty. In-stock and ships same business day from our warehouse.

Compatibility: Designed for the Carrier YAC2480YAC506C packaged unit. Always verify your unit's data plate voltage and VA ratings match before ordering. Our HVAC parts specialists are available to confirm fitment — reach out before you buy if you have any questions. Order today and receive same-day shipping on in-stock OEM parts.

Frequently Asked Questions

Does this Transformer fit my Carrier YAC2480YAC506C — P201-35150?
Yes. This is the factory-specified OEM transformer for the Carrier YAC2480YAC506C — 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 YAC2480YAC506C — 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?
