OEM Carrier 40VA Control Transformer 208/240V to 24V for Model PY3PNA060130NA

This OEM Carrier control transformer (part #HT01BD209) is the factory-specified replacement for the Carrier PY3PNA060130NA packaged unit. The transformer steps down high-voltage supply power (208/240V) to the 24V low-voltage signal used by the thermostat, control board, and all safety circuits. When this part fails, the entire control circuit goes dead — the thermostat goes blank, the unit refuses to start, and fuses in the low-voltage circuit may blow repeatedly. If your system shows zero response to thermostat commands, this transformer is one of the first components to test.

  • Specs: Input 208/240V | Output 24V | 40VA power rating | 50/60 Hz | OEM part number HT01BD209 | Factory-matched performance
  • OEM vs Generic: OEM transformers are wound to exact factory VA and voltage tolerances, protecting sensitive control boards from under-voltage or voltage spike damage. Generic units with loose tolerances can cause nuisance tripping or shorten board life.
  • Install difficulty: 2/5 — Turn off all power at the disconnect and breaker before beginning. Tools needed: flathead and Phillips screwdrivers, wire stripper, multimeter. Label all low-voltage wires before disconnecting. Confirm input and output voltages with a multimeter after installation before restoring full power.
  • Warranty: 1-year OEM factory warranty. In stock and ships same business day from our warehouse.

Compatibility: Designed for the Carrier PY3PNA060130NA packaged unit. Verify input voltage on your unit's data plate — this transformer supports both 208V and 240V primary configurations.

Frequently Asked Questions

Does this Transformer fit my Carrier PY3PNA060130NA?
Yes. This is the factory-specified OEM transformer for the Carrier PY3PNA060130NA. 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 PY3PNA060130NA?
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?
