The transformer steps line voltage (120V) down to the 24V signal used by your thermostat, gas valve, inducer relay, and all low-voltage control components. When this part fails, the entire control circuit goes dark — the furnace will not respond to the thermostat, will not attempt ignition, and may blow a 3A or 5A fuse repeatedly. Replacing the transformer is one of the quickest, most cost-effective repairs in HVAC service.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 120V primary | 24V \/ 12V secondary | 40VA power rating | OEM part number HT01CN001 | Also supersedes HT01CN001A, HT01BJ115, 19EA41612, 19EA42612\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e OEM transformers are wound to exact VA and impedance specs.
