OEM Carrier 50VA Control Transformer P201-35150 for Model YAC60140YACX202AT

This is the genuine OEM Carrier replacement transformer (part number P201-35150) factory-specified for the Carrier YAC60140YACX202AT system. The control transformer steps high-voltage line power (120/208/240 VAC) down to safe low-voltage output (12/24 VAC) to energize your system's control board, thermostat circuit, and all low-voltage control devices. When the transformer fails, the entire control circuit loses power — nothing responds, the thermostat goes blank, and the system becomes completely unresponsive. This is one of the most critical components in your HVAC system's electrical architecture.

• Specs: 50 VA rating | Primary voltage: 120/208/240 VAC | Secondary voltage: 12/24 VAC | 60 Hz | Single phase | CSA listed | Factory OEM part number P201-35150
• OEM vs Generic: This is a genuine Carrier factory-authorized part (Totaline/Carrier Replacement Components Division), meeting exact VA, voltage, and frequency tolerances. Off-brand transformers frequently run outside rated VA capacity, causing control board brownouts, nuisance tripping, or premature 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 verify 24V output after install). Label all low-voltage wires before removal. Verify phasing on multi-tap primary before energizing.
• Warranty: 1-year OEM factory warranty. In stock and ships same business day from our warehouse.

Compatibility: Designed as the factory replacement transformer for the Carrier YAC60140YACX202AT.
