OEM Carrier Transformer 460V Primary / 230V Secondary 1564VA for Model PH3GEAA42000AA

This genuine OEM Carrier transformer (part numbers HT01BC701 and HT01BD242) is the factory-authorized replacement for the Carrier PH3GEAA42000AA packaged unit. The transformer steps down incoming 460V primary power to 230V secondary voltage, delivering the correct operating power to essential control-circuit components throughout the unit. When this transformer fails, you'll typically see a complete loss of control power — the system will not respond to thermostat signals, no contactors will energize, and all downstream components will go offline. In some cases, a failed transformer may blow the low-voltage fuse or trip a breaker without any other obvious cause.

  • Specs: 460V Primary | 230V Secondary | 1564 VA Rating | OEM Part Numbers: HT01BC701 / HT01BD242 | Factory-matched electrical characteristics
  • OEM vs Generic: This is a genuine Carrier factory-authorized part, manufactured to exact design specifications for the PH3GEAA42000AA packaged unit. Generic transformers often deviate in VA rating or winding impedance, risking control board damage or nuisance tripping under load.
  • Install Difficulty: 3/5 — High-voltage wiring is present. Shut off all power at the disconnect and verify zero voltage with a multimeter before proceeding. Tools needed: multimeter, insulated screwdrivers, wire stripper, needle-nose pliers. Label all wires before disconnecting. Recommended for qualified HVAC technicians.
  • Warranty: 1-year OEM manufacturer warranty from date of purchase. In-stock units ship same business day from our warehouse.

Compatibility: Engineered specifically for the Carrier PH3GEAA42000AA packaged unit. Cross-references: HT01BC701 and HT01BD242 are interchangeable OEM part numbers for this application. Always verify primary voltage (460V), secondary voltage (230V), and VA rating (1564VA) against your unit's data plate before ordering. Our fitment team is available to confirm compatibility before you buy — just reach out before placing your order.

How do I replace the transformer on my Carrier OEM Carrier Transformer 460V Pri 230V Sec 1564VA — PH3GEAA42000AA?
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.
