OEM Carrier Control Transformer 208/230V 40VA — HT01CN241 for Model PF4MNB061T00ABAA

This OEM Carrier transformer (part number HT01CN241) is the factory-specified 40VA step-down transformer for the Carrier PF4MNB061T00ABAA fan coil and air handler series. Its job is critical: it steps line voltage (208/230V) down to the 24V signal used by your thermostat, control board, and all low-voltage components. When this transformer fails, absolutely nothing in your control circuit responds — the thermostat goes blank, the system refuses to start, and you may blow a control-circuit fuse. Replacing it with the correct OEM unit restores full system function immediately.

  • Specs: 208/230V Primary | 24V Secondary | 40VA rating | Direct OEM drop-in replacement for Carrier HT01CN241
  • OEM vs Generic: Factory Authorized Parts meet exact Carrier® Corporation specifications for terminal placement, VA rating tolerance, and insulation class — ensuring seamless integration without the risk of underrated generics overheating your control circuit.
  • Install difficulty: 2/5 — Shut off all power to the unit before beginning. Tools needed: flathead and Phillips screwdrivers, wire stripper, multimeter (verify 0V before touching wires). Label all low-voltage wires before disconnecting. The transformer typically mounts to the blower compartment panel with two screws and connects via quick-disconnect or screw terminals.
  • Warranty: 1-year OEM manufacturer warranty. In-stock units ship same business day from our warehouse.

Compatibility: Engineered as the direct OEM replacement for the Carrier PF4MNB061T00ABAA fan coil unit.

Frequently Asked Questions

Does this Transformer fit my Carrier PF4MNB061T00ABAA?
Yes. This is the factory-specified OEM transformer for the Carrier PF4MNB061T00ABAA. 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 PF4MNB061T00ABAA?
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?
