OEM Carrier 40VA Control Transformer 208/230V–24V for Model PF1MNC060T00AAAA

This is the genuine OEM replacement control transformer for the Carrier PF1MNC060T00AAAA fan coil and air handler system. The transformer is the heartbeat of your HVAC control circuit — it steps down line voltage (208/230V) to the 24V signal used by your thermostat, control board, contactors, and zone valves. When this part fails, the result is typically a completely unresponsive system: the thermostat goes blank, nothing clicks on, and no heating or cooling stage can be called. In some cases a failed transformer will trip a fuse on the control board before any visible symptom appears.

• Specs: 208/230V Primary | 24V Secondary | 40VA rating | OEM part number HT01CN241 | Direct factory-spec replacement
• OEM vs Generic: OEM transformers are wound to exact VA and voltage tolerances specified by Carrier's engineers. Undersized or off-tolerance aftermarket units can cause erratic thermostat behavior, nuisance fuse failures, or control board damage over time — making OEM the only recommended choice for this application.
• Install difficulty: 2/5 — Always shut off power at the breaker and confirm zero voltage with a multimeter before disconnecting. Photograph all wiring before removal. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter. Check and replace the 3A or 5A fuse on the control board while you have access — a failed transformer often takes the fuse with it.
• Warranty: 1-year OEM manufacturer warranty. In stock and ships same business day from our warehouse when ordered by 3 PM local time.
