The transformer steps down 120V line voltage to the 24V signal required by your thermostat, contactor coils, gas valve, and control board. When this component fails, the entire control circuit goes dead — your system will appear completely unresponsive, with no thermostat communication and no call-for-heat or call-for-cooling response whatsoever.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 40VA rating | 120V primary input | 24V secondary output | Factory-matched OEM replacement | Part number HT01BD236\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This OEM Carrier transformer is wound to exact factory VA and voltage specifications.
