The transformer steps line voltage (120V) down to the 24V signal required by your thermostat, contactor coil, gas valve, and control board. When this component fails, the entire control circuit loses power — nothing responds to thermostat calls, and the system goes completely dead. It is often one of the first components to inspect when a unit shows zero activity despite confirmed line voltage.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 40VA rated | 120V primary \/ 24V secondary | OEM part number HT01BC116 | Factory-matched output tolerance for reliable low-voltage control\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e OEM transformers are wound to Carrier's exact VA and voltage specifications.
