OEM Carrier Control Transformer 40VA 208/240V to 24V — HT01BD209 for Model PY3PPA060130AB

This OEM Carrier transformer (part #HT01BD209) is the factory-specified replacement for the Carrier PY3PPA060130AB packaged HVAC unit. The transformer steps down 208/240V line voltage to the 24V signal used by your thermostat, control board, contactor coil, and all low-voltage safety circuits. When it fails, the entire control circuit goes dark — the thermostat shows no response, the system won't call for heating or cooling, and no safety faults are logged because the board itself has no power.

  • Specs: Input 208/240V | Output 24V secondary | 40VA power rating | 50/60 Hz compatible | Factory-matched to Carrier PY3PPA060130AB electrical requirements
  • OEM vs Generic: The OEM unit is wound to exact Carrier VA tolerances, ensuring the coil voltage delivered to the contactor and control board stays within spec under full load. Generic transformers often run underrated VA, causing thermal shutdowns and nuisance lockouts during peak demand.
  • Install difficulty: 2/5 — Disconnect all power at the breaker before starting. Tools needed: multimeter (verify 0V before touching terminals), flathead and Phillips screwdrivers, wire stripper, and wire nuts or quick-connects. Label all low-voltage wires before removal. Confirm output voltage (24V ±10%) after installation before closing the panel.
  • Warranty: 1-year OEM factory warranty. In stock and ships same business day from our NationalHVACParts.com warehouse.

Compatibility: Designed for the Carrier PY3PPA060130AB packaged unit. Verify input voltage on your unit's data plate (208V or 240V single-phase) before ordering. Cross-references include HT01CN232 and HT01CN233. Not sure it fits? Contact our fitment team before you order — we verify compatibility on every transformer sale.

Frequently Asked Questions

Does this Transformer fit my Carrier PY3PPA060130AB?
Yes. This is the factory-specified OEM transformer for the Carrier PY3PPA060130AB. 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 PY3PPA060130AB?
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?
Orders placed before 3:00 PM CST ship the same business day. Standard delivery is 2–5 business days anywhere in the continental United States. Express shipping available at checkout. We ship from Houston, TX to all 50 states. 30-day return policy on all parts.
