The transformer's critical job is to step down line-voltage (120V) to the 24V AC signal that powers your thermostat, control board, gas valve, and every other low-voltage component in the system. When it fails, absolutely nothing in the control circuit responds — the thermostat goes blank, the furnace won't call for heat, and the system appears completely dead. A blown transformer is often caused by a short in the 24V circuit, so always check for downstream wiring faults before installing the new unit.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 40VA rated | 120V primary \/ 24V secondary | Direct OEM replacement | Part number HT01BC116 | Factory-matched output tolerance for reliable low-voltage control\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This OEM unit is wound to Carrier's exact VA and voltage specifications.
