OEM Carrier Transformer 40VA 120V/24V for Model HP13PR06000GAKAA

This OEM step-down transformer (part number HT01AW229) is the factory-specified replacement for the Carrier HP13PR06000GAKAA heat pump system. The transformer converts 120V line voltage down to the 24V signal voltage that powers the entire control circuit — including the thermostat, contactor coil, and control board. When this part fails, the system goes completely silent: no thermostat response, no contactor energizing, and no system operation whatsoever. A blown fuse on the secondary side or a measurable loss of 24V output at the control board terminals are the two most common diagnostic indicators.

• Specs: 40VA rating | 120V primary / 24V secondary | Compatible with standard R-410A heat pump control circuits | Factory-matched output tolerance for reliable low-voltage signaling
• OEM vs Generic: The OEM HT01AW229 transformer is wound and rated to Carrier's exact VA and voltage specifications. Generic alternatives often use lower-grade core materials that run hotter and degrade faster, risking repeat failures and secondary board damage.
• Install difficulty: 2/5 — Disconnect power at the breaker before servicing. Tools needed: flathead and Phillips screwdrivers, multimeter, wire nuts or spade connectors. Label all wires before disconnecting the old unit. Verify 24V output with a multimeter before restoring full system power.
• Warranty: 1-year OEM factory warranty. Orders placed before cutoff ship same business day from our warehouse.

Compatibility: Designed for the Carrier HP13PR06000GAKAA heat pump. Always verify your existing transformer's VA rating and primary/secondary voltages against your unit's data plate before ordering. If you're unsure about fitment, our parts specialists can confirm compatibility before you buy — just reach out before placing your order.
