The transformer steps down 120V line voltage to the 24V AC signal that powers your thermostat, control board, and all low-voltage relay circuits. When this component fails, the entire control system goes dark — the thermostat loses power, contactors won't energize, and neither heating nor cooling can be called. A failed transformer is often misdiagnosed as a bad control board, making this an essential first diagnostic check.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 40VA rated | 120V primary \/ 24V secondary | Class 2 control circuit transformer | Factory-matched OEM part number HT01CN236 | Includes built-in circuit breaker protection on most units\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This OEM unit is wound to Carrier's exact VA rating and insulation class, ensuring stable 24V output under full control load.
