OEM Carrier Control Transformer 60VA 115/208/230V–24V for Model PH13NR036000AAAA

This is the factory OEM replacement control transformer for the Carrier PH13NR036000AAAA heat pump system. The transformer steps high-voltage line power (115/208/230 VAC) down to the 24 VAC signal voltage that powers your thermostat, contactor coils, and all low-voltage control circuitry. When this transformer fails, the result is total control-circuit shutdown — the thermostat goes dark, the system will not respond to any call for heating or cooling, and in some cases a tripped 24V fuse is the only clue. Replacing with a genuine OEM unit restores factory-specified output voltage and protects every low-voltage component downstream.

• Specs: 60 VA power rating | 115/208/230 VAC primary (multi-tap) | 24 VAC secondary | 50/60 Hz | Foot-mount configuration | OEM Part Number: HT01AW229
• OEM vs Generic: OEM transformers are wound to Carrier's exact VA and voltage tolerances, ensuring stable 24V output under full load. Generic units frequently run hot under peak demand, shortening the life of contactors and control boards they power.
• Install Difficulty: 2/5 — Shut off power at the breaker and verify zero voltage before disconnecting wires. Tools needed: multimeter, flathead and Phillips screwdrivers, wire nuts or spade terminals. Label all wires before removal. Foot-mount design simplifies positioning.
• Warranty: 1-year OEM factory warranty. In stock and ships same business day from our warehouse.

Compatibility: Designed for the Carrier PH13NR036000AAAA heat pump. Verify primary voltage tap matches your unit's supply voltage (115V, 208V, or 230V) as shown on the equipment data plate before installation. Cross-references: HT01AW229A. Questions about fitment?
