The transformer steps down the incoming 120V line voltage to the 24V AC signal that powers your thermostat, gas valve, inducer relay, and every other low-voltage control component in the system. When this part fails, the entire furnace goes silent — no fan, no ignition attempt, no thermostat response — because the control circuit has lost its power source. A blown fuse on the secondary side is often the first clue; if the fuse keeps blowing, the transformer itself is the likely culprit.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 40VA rating | Primary: 120V AC | Secondary: 24V AC | Foot-mount configuration | Wire-lead connections with insulated female connectors\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine OEM-grade Carrier replacement (current ship part HT680054, direct successor to HT01BC116). OEM units are wound to exact VA and voltage tolerances, preventing under-voltage faults that damage thermostats and control boards.
