It steps down 120V line voltage to the 24V signal used by your thermostat, control board, gas valve, and all low-voltage controls. When the transformer fails, the entire control circuit goes dead — you'll see a blank thermostat, no ignition attempt, and no response from the furnace whatsoever. Replacing it restores full low-voltage function and is one of the most reliable, cost-effective repairs in HVAC service.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e Primary Input: 120VAC | Secondary Output: 24VAC | VA Rating: 40VA | Frequency: 60Hz | Connection Type: Wire Leads | Mounting: Foot-mount | OEM Part Number: HT01BC116 (superseded by HT680054)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e OEM transformers are wound and tested to exact factory VA and voltage tolerances.
