OEM Carrier Control Transformer 50VA 120/208/240-12/24V for Model YAC3080YAC106K

This OEM Carrier transformer (part number P201-35150) is the factory-specified step-down transformer for the Carrier YAC3080YAC106K. It converts incoming line voltage (120, 208, or 240 VAC) down to a safe 12/24 VAC to power the low-voltage control circuit — including the control board, thermostat, and all associated safety devices. When this transformer fails, the entire control circuit loses power: the thermostat goes blank, the system becomes completely unresponsive, or protective fuses blow repeatedly with no apparent cause.

  • Specs: 50VA rating | Primary: 120/208/240 VAC multi-tap | Secondary: 12/24 VAC | 60 Hz | Single-phase | CSA listed | Dimensions approx. 3.8″L × 3.1″W × 2.2″H
  • OEM vs Generic: This is a genuine Carrier/Totaline factory-authorized part. OEM transformers are wound and insulated to exact VA and thermal specs. Undersized or off-tolerance generic transformers can overheat, blow secondary fuses, or damage sensitive control boards — making the OEM choice a true long-term investment.
  • Install difficulty: 3/5 — Line voltage is present inside the unit. Always shut off power at the disconnect AND the breaker before servicing. Tools needed: flathead and Phillips screwdrivers, wire stripper, multimeter, needle-nose pliers. Photograph all wiring connections before removal. If you are not comfortable working around line voltage, contact a licensed HVAC technician.
  • Warranty: 1-year OEM factory warranty. In stock and ships same business day from our warehouse.

Compatibility: Engineered as the direct OEM replacement for Carrier model YAC3080YAC106K. The multi-tap primary (120/208/240V) makes this transformer versatile across commercial and residential voltage configurations. Always verify your unit's data plate voltage requirements before wiring. Have a fitment question? Our parts specialists confirm compatibility before you order — reach out before purchasing.
