OEM Carrier Control Transformer 208/230V 40VA (HT01CN241) for Model PF1MNC030T00AAAA

This OEM Carrier transformer (part number HT01CN241) is the factory-specified 40VA control transformer for the Carrier PF1MNC030T00AAAA fan coil and air handler system. The transformer steps down the 208/230V line voltage from the primary circuit to a safe 24V signal used to power the control board, thermostat wiring, and all low-voltage components. When this transformer fails, the entire control circuit goes dead — your thermostat shows no response, the system won't call for heating or cooling, and no faults can even be logged. Replacing it restores full system communication and operation.

• Specs: 208/230V primary | 24V secondary | 40VA power rating | Direct OEM drop-in replacement for Carrier HT01CN241
• OEM vs Generic: This is a genuine Carrier Factory Authorized Part built to exact OEM tolerances. Generic transformers often carry imprecise VA ratings that can overload the secondary circuit, trip breakers, or damage connected control boards over time.
• Install difficulty: 2/5 — Disconnect all power before beginning. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter (to verify 24V output after install). Label all low-voltage wires before removing the old unit. Installation typically takes 20–40 minutes for an experienced DIYer.
• Warranty: 1-year OEM manufacturer warranty. In stock and ships same business day from our warehouse.
