The transformer steps down 120V line voltage to the 24V signal used by your thermostat, control board, and low-voltage control circuit. When the transformer fails, the entire control circuit goes dark — the thermostat goes blank, the system won't respond to any call for heating or cooling, and you may notice a burning smell or a tripped fuse on the secondary side.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 40VA rating | Primary: 120V | Secondary: 24V | OEM part number HT01CN236 | Factory-matched output tolerances for stable low-voltage operation\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e OEM transformers are wound to exact VA and voltage specifications for the Carrier FA4ANC036008AGAA control board.
