OEM Carrier Control Transformer 60VA 115/208/230V for Model PH13NR02400GACAA

This is the genuine OEM factory-authorized replacement control transformer for the Carrier PH13NR02400GACAA heat pump system. The transformer steps down high-voltage line power (115/208/230V primary) to 24V AC for the low-voltage control circuit, powering the thermostat, contactor coil, and all control board logic. When this transformer fails, the entire control circuit goes dead — the thermostat goes blank, the contactor won't energize, and the system will not respond to any call for heating or cooling. If your system shows absolutely no 24V output at the control board terminals and you've ruled out a tripped breaker, this transformer is almost always the culprit.

• Specs: 60 VA rating | Primary voltage: 115/208/230V AC | Secondary voltage: 24V AC | Foot-mounted configuration | OEM Part Number: HT01AW229
• OEM vs Generic: This is a genuine Carrier Factory Authorized Part (FAP), engineered to exact VA capacity and thermal limits for the PH13NR02400GACAA platform. Generic substitutes are often under-rated in VA, causing thermal trips under full control-circuit load and premature failure.
• Install difficulty: 2/5 — Shut off all power at the breaker before starting. Tools needed: flathead and Phillips screwdrivers, multimeter, needle-nose pliers, wire nuts or spade connectors. Label and photograph all wiring before disconnecting. Verify 24V output at secondary terminals after installation before restoring full system power.
• Warranty: 1-year OEM factory warranty. In stock — ships same business day from our warehouse.

Compatibility: Direct OEM replacement for Carrier PH13NR02400GACAA heat pump systems. Always verify your existing transformer's VA rating and primary voltage configuration against your unit's data plate before ordering. Our team is available to confirm fitment prior to purchase — don't guess on control circuit components.
