The transformer steps down 120V line voltage to the 24V signal required by your thermostat, contactor coil, gas valve, and all low-voltage controls. When it fails — due to a shorted control wire, failed component, or age — nothing in the system will respond: the thermostat goes dark, the contactor won't pull in, and the unit sits completely dead with no call for heat or cool.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 40VA rated | 120V primary \/ 24V secondary | Replaces OEM part number HT01BD236 | Factory-matched for Carrier packaged unit control boards\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e The OEM HT01BD236 transformer is wound and potted to Carrier's exact VA rating and insulation class.
