OEM Carrier Control Transformer 40VA 208/240V to 24V for Model PY2PNB060115AA

The Carrier HT01BD209 is the factory OEM step-down transformer for the PY2PNB060115AA gas furnace. Its sole job is to convert high-voltage line power (208/240V) down to the 24V signal that powers your thermostat, control board, and every low-voltage component in the system. When this transformer fails, the entire control circuit goes dark — the thermostat goes blank, the system won't respond to any call for heat or cooling, and nothing in the unit will initiate a cycle.

  • Specs: Input 208/240V | Output 24V | 40VA power rating | 50/60Hz | OEM Part # HT01BD209 | Direct factory replacement
  • OEM vs Generic: OEM transformers are wound and insulated to exact factory tolerances, ensuring stable 24V output under load. Generic units can drift in output voltage, causing nuisance lockouts, erratic board behavior, or premature control board failure.
  • Install difficulty: 2/5 — Shut off power at the breaker and confirm zero voltage with a multimeter before touching any wiring. Tools needed: flathead and Phillips screwdrivers, wire stripper, multimeter. Photograph all wiring connections before disconnecting. Mount securely and verify 24V output before reassembling the panel.
  • Warranty: 1-year OEM factory warranty. In stock and ships same business day from our warehouse.

Compatibility: Verified fit for Carrier model PY2PNB060115AA. Always confirm the existing transformer's input voltage and VA rating on your unit's data plate before ordering. Our parts specialists are available to verify fitment — reach out before you order if you have any questions.

Frequently Asked Questions

Does this Transformer fit my Carrier PY2PNB060115AA?
Yes. This is the factory-specified OEM transformer for the Carrier PY2PNB060115AA. 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 PY2PNB060115AA?
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?
