The transformer steps down 120V line voltage to the 24V AC signal that powers your thermostat, control board, gas valve, and every other low-voltage control circuit in the system. When it fails, the entire control system goes dark — no thermostat response, no ignition sequence, and no heat. A failed transformer is one of the most commonly misdiagnosed furnace faults; always verify 24V output at the secondary terminals with a multimeter before condemning the control board.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 120V primary \/ 24V secondary | 40VA rated | Foot-mount chassis | OEM part number HT01BC117 (supersedes HT01BC117A) | Cross-references: Basler Electric BE161840GDD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine Carrier Factory Authorized Part wound to exact VA and voltage tolerances.
