The transformer steps down line voltage from 208\/230V to 24V AC to power the low-voltage control circuit — the backbone of your system's thermostat, contactor coil, and safety controls. When this transformer fails, nothing in the system responds: the thermostat goes blank, the blower won't start, and the unit sits completely dead despite having line power present.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 208\/230V Primary | 24V Secondary | 40VA rated | OEM part number HT01CN241 | Factory-matched Basler Electric construction\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine Carrier OEM transformer built to exact voltage and VA tolerances. Generic transformers can run undersized or out-of-spec, causing erratic control board behavior, nuisance tripping, or premature contactor coil failure.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstall difficulty: 2\/5\u003c\/strong\u003e — Always disconnect power at the disconnect box and breaker before servicing. Tools needed: flathead and Phillips screwdrivers, wire stripper, multimeter to verify 24V output after install. Photograph all wire connections before removal. Confirm primary voltage tap matches your supply voltage (208V or 230V).\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWarranty:\u003c\/strong\u003e 1-year OEM manufacturer's warranty.

Verify your unit's data plate shows a 208\/230V primary and 24V secondary control circuit before ordering. This transformer is also used across multiple Carrier, Bryant, and ICP-family products sharing the same control circuit spec. Need fitment confirmation?
