When the transformer fails, the entire control circuit loses power — the result is a furnace that's completely unresponsive: no ignition attempt, no inducer start, and a blank or unresponsive thermostat.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 120V Primary | 24V \/ 12V Secondary | 40VA Rating | OEM Part Number HT01CN001 | Replaces legacy part numbers HT01BJ115, 19EA41612, and 19EA42612\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine Carrier Factory Authorized Part.

Tools needed: flathead and Phillips screwdrivers, wire stripper, multimeter. Label all low-voltage wires before disconnecting. A multimeter test on the secondary (expect ~24–26V AC at no load) confirms the new transformer is good before buttoning up the panel.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWarranty:\u003c\/strong\u003e 1-year OEM factory warranty included.
