OEM Carrier Control Transformer 40VA 208/240V to 24V for Model PY3PPA060130NB

This OEM Carrier control transformer (part #HT01BD209) is the factory-specified replacement for the Carrier PY3PPA060130NB packaged unit. The transformer steps down the 208/240V line voltage to the 24V signal used by the control board, thermostat, contactor coil, and every other low-voltage component in the system. When it fails, the entire control circuit goes dark — you'll see a blank thermostat, no response to calls for heating or cooling, and potentially a tripped 5A fuse on the board from a shorted secondary.

  • Specs: 208/240V Primary | 24V Secondary | 40VA capacity | 50/60 Hz | Direct OEM replacement for HT01BD207, HT01CN232, and 9076-00
  • OEM vs Generic: This is a genuine Carrier OEM part, wound to factory VA and voltage tolerances. Under-spec'd aftermarket transformers run hot, trip thermal cutoffs prematurely, and can damage control boards by delivering unstable voltage.
  • Install difficulty: 2/5 — Shut off all power at the disconnect and breaker before beginning. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter (verify 24V output after install). Always photograph the existing wiring harness before disconnecting leads.
  • Warranty: 1-year OEM factory warranty. Ships same business day from our warehouse.

Compatibility: Designed for the Carrier PY3PPA060130NB packaged unit. Verify your existing transformer's primary voltage and VA rating on the unit's data plate before ordering. Cross-references OEM part numbers HT01BD207, HT01CN232, and 9076-00. Questions about fitment? Our team verifies compatibility before you order — contact us today and we'll ship it out fast.

How do I replace the transformer on my Carrier OEM Carrier Control Transformer 40VA 208/240V–24V — PY3PPA060130NB?
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.
