The transformer converts 120V line voltage down to the 24V AC signal that powers the control board, thermostat circuit, gas valve, and all low-voltage safety controls. When this transformer fails, the entire low-voltage control circuit goes dead — your thermostat loses communication, the furnace won't respond to any call for heat, and nothing works. It is one of the most fundamental components in the entire system.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 40VA rating | 120V primary | 24V secondary | 60Hz | Single-phase | Replaces OEM part# 322666-701 (superseded by HT680054)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e OEM transformers are wound to exact factory VA and voltage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 voltage fluctuations.
