OEM Carrier 40VA Control Transformer 208/230V–24V (HT01CN241) for Model PF4MNA060000AAAA

This OEM Carrier control transformer (part number HT01CN241) is the factory-specified replacement for the Carrier PF4MNA060000AAAA fan coil and air handler unit. The transformer steps down line voltage from 208/230V to 24V AC to power the low-voltage control circuit — the backbone of your system's thermostat, contactor coil, and safety controls. When this transformer fails, nothing in the system responds: the thermostat goes blank, the blower won't start, and the unit sits completely dead despite having line power present.

  • Specs: 208/230V Primary | 24V Secondary | 40VA rated | OEM part number HT01CN241 | Factory-matched Basler Electric construction
  • OEM vs Generic: This is a genuine Carrier OEM transformer built to exact voltage and VA tolerances. Generic transformers can run undersized or out-of-spec, causing erratic control board behavior, nuisance tripping, or premature contactor coil failure.
  • Install difficulty: 2/5 — Always disconnect power at the disconnect box and breaker before servicing. Tools needed: flathead and Phillips screwdrivers, wire stripper, multimeter to verify 24V output after install. Photograph all wire connections before removal. Confirm primary voltage tap matches your supply voltage (208V or 230V).
  • Warranty: 1-year OEM manufacturer's warranty. In stock — ships same business day when ordered by 5 PM local time.

Compatibility: Designed for the Carrier PF4MNA060000AAAA fan coil/air handler. Verify your unit's data plate shows a 208/230V primary and 24V secondary control circuit before ordering. This transformer is also used across multiple Carrier, Bryant, and ICP-family products sharing the same control circuit spec. Need fitment confirmation?

Frequently Asked Questions

Does this Transformer fit my Carrier PF4MNA060000AAAA?
Yes. This is the factory-specified OEM transformer for the Carrier PF4MNA060000AAAA. It is a direct drop-in replacement that fits without modification. Always verify the model number on your equipment nameplate before ordering.
How do I replace the transformer on my Carrier PF4MNA060000AAAA?
Difficulty: Medium (30–45 min)
Step 1: Turn off breaker. Step 2: Photo wiring connections. Step 3: Disconnect wires from old transformer. Step 4: Remove mounting hardware. Step 5: Install new transformer, reconnect wires matching voltage ratings. Step 6: Verify 24V output with multimeter.
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?
Many Carrier parts are cross-compatible with Bryant and Payne since all three brands are manufactured by Carrier Global Corporation. 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.
How fast does National HVAC Parts ship?
