OEM Carrier 50VA Control Transformer P201-35150 for Model YAC48110YACX104AC

This is the factory OEM replacement control transformer for the Carrier YAC48110YACX104AC packaged unit. The transformer steps down high-voltage line power — 120, 208, or 240 VAC — to a safe 12/24VAC output that powers your system's control board, thermostat, and all low-voltage control circuits. When the transformer fails, the entire control circuit goes dead: the thermostat goes blank, the system won't respond to any commands, and you may find a blown fuse on the control board. Replacing this part restores full low-voltage power and gets your system running again.

• OEM vs Generic: This is a genuine Carrier/Totaline factory-authorized transformer wound to exact VA and voltage tolerances. Generic aftermarket transformers often run undersized VA ratings, causing overheating, premature fuse failure, and unreliable control circuit performance.
• Install difficulty: 3/5 — Disconnect all power before servicing. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, wire stripper, multimeter. Photograph all wiring connections before disconnecting. Verify primary tap selection matches your supply voltage before energizing.
