OEM Carrier Control Transformer 50VA 120/208/240-12/24V for Model YAC3080YAC506T

This OEM control transformer (part# P201-35150) is the factory-specified replacement for the Carrier YAC3080YAC506T HVAC system. The transformer steps down incoming 120/208/240 VAC line voltage to a safe 12/24 VAC output to power your system's control board, thermostat circuit, and all low-voltage devices. When this transformer fails, the entire control circuit goes dead — you'll see a blank thermostat, no response to calls for heating or cooling, or a tripped low-voltage fuse. Replacing this part restores the full control circuit instantly.
