OEM Carrier Control Transformer 208/240V to 24V 40VA for Model PY2PPB060115AA

This OEM Carrier control transformer (part #HT01BD209) is the factory-specified replacement for the Carrier PY2PPB060115AA packaged unit. The transformer steps down high-voltage line power (208/240V) to the 24V signal that powers your thermostat, control board, and all low-voltage control circuits. When this part fails, the entire control system goes dark — your thermostat loses power, no call for heat or cooling is recognized, and the system becomes completely unresponsive. It is often the first component to check when nothing works at all.

  • Specs: 208/240V primary input | 24V secondary output | 40VA power rating | 50/60 Hz | OEM part number HT01BD209 | Factory-matched to Carrier PY2PPB060115AA
  • OEM vs Generic: OEM transformers are wound to exact VA and voltage tolerances required by Carrier. Undersized or off-tolerance aftermarket units can cause nuisance tripping, board damage, or premature failure of control circuits.
  • Install difficulty: 2/5 — Shut off all power to the unit before starting. Tools needed: flathead and Phillips screwdrivers, wire stripper, multimeter. Label all wires before disconnecting, and confirm primary and secondary terminal orientation before reconnecting.
  • Warranty: 1-year OEM factory warranty. In stock and ships same business day from our warehouse.

Compatibility: Designed as a direct OEM replacement for Carrier model PY2PPB060115AA. Verify your unit's primary voltage (208V or 240V) on the data plate before ordering to confirm this is the correct transformer. Have questions about fitment?

Frequently Asked Questions

Does this Transformer fit my Carrier PY2PPB060115AA?
Yes. This is the factory-specified OEM transformer for the Carrier PY2PPB060115AA. 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 PY2PPB060115AA?
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?
