It converts 120V line voltage to the 24V AC signal that powers your thermostat, control board, gas valve, and all low-voltage control circuit components. When this transformer fails, the entire control circuit goes dark — the thermostat shows no response, the furnace won't call for heat, and no fault codes are generated because the board itself has no power.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e Input: 120V AC | Output: 24V AC | VA Rating: 40VA | Class 2 transformer | Factory-matched OEM replacement for part number \u003cstrong\u003eHT01BC116\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e OEM transformers are wound to exact factory VA and voltage tolerances, protecting sensitive control boards from undervoltage or overcurrent conditions.
