The transformer steps down 120V line voltage to the 24V signal voltage required by your thermostat, control board, gas valve, and all low-voltage control components. When the transformer fails, the entire control circuit goes dead — your thermostat goes blank, nothing responds, and the system will not attempt ignition. If you have 120V at the furnace but 0V at the secondary terminals, this transformer is your fix.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 40VA rating | Primary: 120V AC | Secondary: 24V AC | OEM part number HT01BC116 | Replaces factory-installed unit exactly\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is the genuine Carrier OEM transformer wound to exact VA and voltage tolerances. Generic transformers frequently underperform under full load — powering a contactor, gas valve, and control board simultaneously — leading to voltage sag and nuisance lockouts. The OEM unit is built to sustain continuous 40VA draw without thermal degradation.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstall difficulty: 2\/5\u003c\/strong\u003e — Shut off power at the disconnect and breaker before beginning.
