OEM Carrier Control Transformer 208/230V 40VA for Model PF1MNC049T00AAAA

This OEM control transformer (part #HT01CN241) is the factory-specified replacement for the Carrier PF1MNC049T00AAAA fan coil and air handler unit. The transformer steps down the 208/230V line voltage to a safe 24V signal used to power the control board, thermostat circuit, and all low-voltage control components. When this part fails, the entire control circuit goes dead — the thermostat loses power, the system won't respond to calls for heating or cooling, and no status lights appear on the board. Replace it before misdiagnosing a control board or thermostat.
