OEM Carrier 50VA Control Transformer 120/240–24V for Model YAC2480YACX106C

This is the genuine OEM factory-replacement control transformer (part# P201-35150) for the Carrier YAC2480YACX106C. The transformer is the backbone of your system's low-voltage control circuit — it steps down 120/208/240V line voltage to a safe 12/24V to power the control board, thermostat, and all low-voltage switching components. When the transformer fails, the entire control circuit goes dark: your thermostat will show no power, the system will not respond to calls for heating or cooling, and no error codes will display because the board itself has lost power.

• Specs: 50VA rating | Primary: 120/208/240 VAC multi-tap | Secondary: 12/24 VAC | 60 Hz | Single phase | CSA listed | Factory-authorized Totaline® / Carrier OEM part
• OEM vs Generic: OEM transformers are wound and insulated to exact factory VA tolerances, ensuring the control board and thermostat receive stable, clean 24V. Generic aftermarket units frequently underperform their rated VA, causing nuisance trips, erratic thermostat behavior, and premature board failure.
• Install difficulty: 2/5 — Shut off all power at the disconnect and breaker before proceeding. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter (to verify 0V before touching terminals). Label all wires before disconnecting. Typical swap time: 20–30 minutes for an experienced technician.
• Warranty: 1-year OEM factory warranty. In stock — ships same business day from our warehouse.

Compatibility: Engineered as the factory-specified transformer for the Carrier YAC2480YACX106C. Always verify the primary voltage tap (120V or 240V) matches your unit's supply voltage before wiring. If you are unsure of fitment, our technical team is available to confirm before you order — no guesswork required.
