OEM Carrier 40VA Control Transformer 208/230V–24V (HT01CN241) for Model PF1MNC048T00AAAA

This is the genuine OEM Carrier HT01CN241 control transformer — the factory-specified replacement for the Carrier PF1MNC048T00AAAA fan coil unit. The transformer steps down line voltage (208/230V primary) to the 24V secondary signal required to power the thermostat, control board, and all low-voltage switching circuits throughout your system. When this component fails, the entire control circuit loses power: your thermostat goes dark, relays won't energize, and neither heating nor cooling will operate — even if all other components are functioning perfectly.

• Specs: 208/230V Primary | 24V Secondary | 40VA rated | Direct OEM drop-in replacement | Part number HT01CN241
• OEM vs Generic: This factory-authorized OEM transformer is wound to exact Carrier specifications and tolerances, ensuring stable 24V output under full load. Aftermarket units frequently under-deliver VA capacity, causing intermittent lockouts, nuisance tripping of the control board fuse, and premature failure of low-voltage components.
• Install difficulty: 2/5 — Always shut off power at the breaker before beginning. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter (to verify 24V output post-install). Photograph or label all low-voltage wiring before disconnecting. Standard spade or screw-terminal connections.
• Warranty: 1-year OEM manufacturer warranty included. In-stock units ship same business day from our warehouse when ordered before cutoff.
