The transformer steps down 120V line voltage to the 24V signal required by your thermostat, control board, gas valve, and all low-voltage control components. When this part fails, the entire control circuit loses power — the result is a completely unresponsive system: no thermostat display response, no inducer startup, and no heat. A blown fuse or burnt smell near the control board are common signs the transformer has failed or been overloaded.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 40VA rated | Primary: 120V | Secondary: 24V | OEM Part# HT01BC116 | Factory-matched output for stable low-voltage control circuit performance\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This OEM transformer is wound to Carrier's exact VA and voltage tolerance specifications.
