OEM Carrier 40VA Transformer 208/230V–24V for Model PF1MNC036T00AAAA (HT01CN241)

This OEM Carrier transformer (part number HT01CN241) is the factory-specified 24V control circuit transformer for the Carrier PF1MNC036T00AAAA fan coil and air handler unit. The transformer steps down the 208/230V line voltage to the 24V AC signal that powers every low-voltage control function in your system — including the thermostat, contactors, and control board. When this transformer fails, the entire control circuit goes dead: the thermostat goes blank, the system refuses to start, and no low-voltage components respond. Replacing it with the correct OEM part restores factory-spec voltage regulation and ensures stable, reliable operation.

  • Specs: 40VA capacity | 208/230V primary voltage | 24V secondary output | 60Hz | Factory OEM part number HT01CN241 — direct plug-in replacement with no modifications required
  • OEM vs Generic: OEM transformers are wound to exact Carrier tolerances for consistent 24V output under load. Generic alternatives often exhibit voltage sag under peak demand, causing erratic thermostat behavior, nuisance lockouts, or premature control board failure.
  • Install difficulty: 2/5 — Shut off power at the breaker and confirm zero voltage with a multimeter before beginning. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter. Photograph all low-voltage wiring connections before disconnecting. Secure all wire nuts fully after reinstallation and verify 24V output before closing the unit.
  • Warranty: 1-year OEM manufacturer warranty. In stock and ships same business day from our warehouse when ordered by 3 PM local time.

Compatibility: Engineered as a direct OEM replacement for the Carrier PF1MNC036T00AAAA fan coil/air handler. Verify your unit's data plate shows a 208/230V primary and 24V secondary requirement before ordering. Our technical team is available to confirm fitment — contact us before you buy if you have any questions.

Frequently Asked Questions

Does this Transformer fit my Carrier PF1MNC036T00AAAA?
Yes. This is the factory-specified OEM transformer for the Carrier PF1MNC036T00AAAA. 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 PF1MNC036T00AAAA?
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?
