OEM Carrier 40VA Control Transformer 208/230V–24V (HT01CN241) for Model PF4MNA060000AAAA

This OEM Carrier control transformer (part number HT01CN241) is the factory-specified replacement for the Carrier PF4MNA060000AAAA fan coil and air handler unit. 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.

• Specs: 208/230V Primary | 24V Secondary | 40VA rated | OEM part number HT01CN241 | Factory-matched Basler Electric construction
• OEM vs Generic: 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.
• Install difficulty: 2/5 — 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).
• Warranty: 1-year OEM manufacturer's warranty. In stock — ships same business day when ordered by 5 PM local time.

Compatibility: Designed for the Carrier PF4MNA060000AAAA fan coil/air handler. 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?
