OEM Carrier Transformer 460V Pri / 230V Sec / 1564VA for Model PH4GEXA36000AA

This genuine OEM Carrier transformer (part number HT01BC701) is the factory-specified power transformer for the Carrier PH4GEXA36000AA packaged heat pump unit. Unlike a standard 40VA control transformer, this is a high-capacity 1,564VA step-down transformer that converts 460V primary power to 230V secondary for powering critical internal loads within the unit. When it fails, the result is immediate and unmistakable: complete loss of power to downstream components, a dead thermostat, or the system failing to respond to any command. Buzzing, burning smells, or tripped breakers are also common indicators of transformer failure.

  • Specs: 460V Primary | 230V Secondary | 1,564VA Rating | 60Hz | OEM Part # HT01BC701 | Cross-reference: RC6800182 / BE33426001
  • OEM vs Generic: This high-VA transformer operates at factory-engineered tolerances critical for protecting downstream loads. Off-brand substitutes with loose VA or voltage ratings risk under-powering components or causing premature failure of motors and control boards.
  • Install difficulty: 3/5 — This is a line-voltage (460V) transformer replacement. Always lock out/tag out power at the disconnect before servicing. Tools needed: multimeter, insulated screwdrivers, wire stripper, and torque driver. Verify primary and secondary voltages before energizing. Recommended for qualified HVAC technicians.
  • Warranty: 1-year OEM factory warranty. Ships same business day from our warehouse.

Compatibility: Designed as the direct OEM replacement for Carrier model PH4GEXA36000AA packaged heat pump units. Verify your unit's primary voltage (460V) and VA requirement against your data plate before ordering. Cross-references include RC6800182 and BE33426001. Our technical team is available to confirm fitment before you order — call or chat today.

How do I replace the transformer on my Carrier OEM Carrier Transformer 460V Pri 230V Sec 1564VA — PH4GEXA36000AA?
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.
