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. Verify your unit's data plate shows a 208/230V primary and 24V/40VA secondary requirement before ordering. Have a fitment question?

My thermostat has no power. What failed?
Thermostat with no display = failed 24V transformer (or blown control board fuse). Check the 3A/5A fuse on the control board first ($1–$5 fix). If fuse is good but no 24V output from transformer, replace transformer.
Is this transformer compatible with Bryant or Payne too?

The same physical part is often used across brand labels with different model numbers. To verify: check your Bryant or Payne equipment service manual for cross-compatible part numbers, or email info@nationalhvacparts.com with your model number.
Should I use OEM or aftermarket for my Carrier transformer?
OEM recommended for reliability and warranty compatibility. OEM parts match exact factory specifications for proper fit, performance, and safety. While aftermarket alternatives cost less upfront, the risk of improper fit and reduced lifespan usually makes OEM the better value long-term.
