OEM Carrier Control Transformer 40VA 208/230V–24V for Model PY3GPAA60130AA

This genuine OEM Carrier control transformer (part #HT01BD209) is the factory-specified replacement for the Carrier PY3GPAA60130AA packaged unit. The transformer steps down 208/230V line voltage to 24V AC to power the low-voltage control circuit — including the thermostat, contactor coil, gas valve solenoid, and control board. When this transformer fails, the entire system goes dark: the thermostat loses power, nothing responds to calls for heating or cooling, and no fault codes appear on the board. A failed transformer is often misdiagnosed as a board failure, making correct identification critical before ordering.

  • Specs: 208/230V primary | 24V secondary | 40VA rating | 50/60 Hz | Part # HT01BD209 | Also replaces HT01BD207, HT01CN232, and 9076-00
  • OEM vs Generic: This is a genuine Carrier OEM transformer, wound to exact factory VA and voltage tolerances. Undersized or off-spec generic transformers can overheat, trip internal breakers, or cause nuisance faults on sensitive control boards.
  • Install difficulty: 2/5 — Turn off power at the disconnect before starting. Tools needed: flathead and Phillips screwdrivers, wire nuts or spade connectors, multimeter. Label all wire connections before removal. Verify 24V output with a meter after installation before closing the panel.
  • Warranty: 1-year OEM factory warranty. Ships same business day from our warehouse — get your system back online fast.

Compatibility: Fits Carrier model PY3GPAA60130AA packaged units. Verify input voltage (208V or 230V) on your unit's data plate before ordering. Cross-reference part numbers HT01BD207, HT01CN232, and 9076-00 are confirmed factory supersessions. Questions about fitment?

Frequently Asked Questions

Does this Transformer fit my Carrier PY3GPAA60130AA?
Yes. This is the factory-specified OEM transformer for the Carrier PY3GPAA60130AA. 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 PY3GPAA60130AA?
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?
