OEM Carrier Control Transformer 208/230V 40VA (HT01CN241) for Model PF1MNC024T00AAAA

This OEM Carrier transformer (part number HT01CN241) is the factory-specified 40VA step-down transformer for the Carrier PF1MNC024T00AAAA fan coil / air handler unit. The transformer steps line voltage (208/230V primary) down to the 24V AC signal that powers your thermostat, control board, and all low-voltage switching circuits. When this transformer fails, the entire control circuit goes dead — the thermostat loses power, the system won't respond to any calls for heating or cooling, and in some cases a tripped internal fuse or burnt winding is visible on inspection.

• Specs: 208/230V Primary | 24V Secondary | 40VA rated | Direct OEM drop-in replacement for Carrier PF1MNC024T00AAAA | Factory ±3% voltage tolerance
• OEM vs Generic: OEM transformers are wound and potted to Carrier's exact VA and insulation specifications. Generic units may underperform at rated load, leading to brownouts on the 24V circuit, nuisance lockouts, or premature contactor coil failure.
• Install difficulty: 2/5 — Disconnect power at the breaker before starting. Tools needed: flathead and Phillips screwdrivers, multimeter (to verify 24V output post-install), and wire nuts or spade terminals. Always verify primary voltage at the line side before energizing.
• Warranty: 1-year OEM manufacturer warranty. In stock and ships same business day from our warehouse.

Compatibility: Engineered as a direct OEM replacement for the Carrier PF1MNC024T00AAAA air handler. This transformer also fits other Carrier, Bryant, and ICP family units specifying the HT01CN241.
