OEM Carrier 40VA Transformer 208/230V to 24V — Model PF1MNC061T00AAAA (HT01CN241)

This is the genuine OEM replacement transformer for the Carrier PF1MNC061T00AAAA fan coil and air handler systems. The transformer steps down 208/230V line voltage to the 24V AC signal that powers your entire control circuit — thermostat, relays, reversing valves, and the control board all depend on it. When this transformer fails, nothing responds: the thermostat goes blank, the system refuses to start, or the 24V fuse blows repeatedly with no other apparent cause. Replacing it with the correct OEM unit (Part No. HT01CN241) restores the full control circuit immediately.

• Specs: 40VA power rating | 208/230V primary input | 24V AC secondary output | Basler Electric model BE28316007 | Factory-matched OEM tolerances
• OEM vs Generic: OEM transformers are wound to exact VA and voltage tolerances specified by Carrier engineering. Undersized or off-tolerance aftermarket units can cause erratic thermostat behavior, nuisance fuse blowing, and premature control board failure.
• Install difficulty: 2/5 — Power down the unit and confirm zero voltage at the primary terminals before disconnecting. Tools needed: multimeter, flathead and Phillips screwdrivers, wire nuts or quick-connect terminals. Photograph all wire connections before removal. The 24V secondary circuit must be checked for shorts before energizing the new transformer.
• Warranty: 1-year OEM manufacturer warranty. In-stock orders ship same business day from our warehouse.
