The transformer steps down 120V line voltage to 24V to power the entire low-voltage control circuit — including the thermostat, contactor coils, gas valve, and control board. When this part fails, nothing in the system responds: the thermostat goes dark, the unit won't call for heating or cooling, and the system appears completely dead.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e Input: 120V AC | Output: 24V AC | Rating: 40VA | OEM Part Number: HT01BD236 | Factory-matched for C50A202061 packaged units\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e OEM transformers are wound and tested to Carrier's exact VA and voltage tolerances.
