OEM Carrier 50VA Control Transformer 120/240V–24V for Model YAC2480YACX106T

This is the genuine OEM factory-specified control transformer for the Carrier YAC2480YACX106T HVAC system. The transformer steps down line voltage (120/208/240 VAC) to a safe 12/24 VAC to power the control board, thermostat, and all low-voltage control circuit components. When this transformer fails, you'll typically experience a completely unresponsive thermostat, no system response to calls for heating or cooling, or tripped low-voltage fuses — because without the 24V signal, the entire control circuit goes dark.

• Specs: 50 VA rating | Primary: 120/208/240 VAC | Secondary: 12/24 VAC | 60 Hz | Single phase | CSA listed | OEM part number P201-35150
• OEM vs Generic: This is the factory-authorized Carrier/Totaline part engineered to exact VA and voltage tolerances for the YAC2480YACX106T. Generic transformers often run at reduced VA capacity under load, causing nuisance breaker trips and premature control board failure.
• Install difficulty: 2/5 — Shut off all power at the disconnect and breaker before beginning. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter (to confirm 0V before touching terminals). Label all wiring before disconnecting. A typical swap takes 20–30 minutes.
• Warranty: 1-year OEM factory warranty. In-stock and ships same business day from our warehouse.
