OEM Carrier Control Transformer 50VA 120/240-24V for Model YAC2480YAC506T (P201-35150)

This is the genuine OEM factory-specified control transformer for the Carrier YAC2480YAC506T HVAC system. The transformer steps down incoming line voltage — 120/208/240 VAC — to a safe 24 VAC output that powers the system's control board, thermostat circuit, and all low-voltage switching devices. When this transformer fails, the entire control circuit goes dead: your thermostat displays nothing, the system refuses to respond to any call for heating or cooling, or a fuse repeatedly blows on the control board secondary side.

• Specs: 50 VA rating | Primary voltage: 120/208/240 VAC multi-tap | Secondary voltage: 12/24 VAC | Single phase | 60 Hz | CSA listed | OEM Part # P201-35150 (also cross-references Totaline P201-35150)
• OEM vs Generic: This is a genuine Carrier/Totaline factory-authorized part built to exact VA rating and insulation class. Generic aftermarket transformers frequently ship with mismatched VA ratings or loose terminal connections — causing nuisance fuse failures and voiding equipment warranties.
• Install difficulty: 3/5 — Shut off all power at the breaker before starting. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter (verify 0V before touching any wire). Label all wiring before disconnecting primary and secondary leads. Confirm correct primary tap for your supply voltage (120V or 240V) before energizing.
• Warranty: 1-year OEM manufacturer warranty. In stock and ships same business day from our warehouse.
