OEM Carrier 60VA Control Transformer HT01AW229 for Model PH13NR02400GAHAA

This is the factory OEM control transformer for the Carrier PH13NR02400GAHAA heat pump system. The transformer steps down high-voltage line power (115, 208, or 230V primary) to the 24V AC signal that drives the entire low-voltage control circuit — including the thermostat, contactor coil, and any connected zone controls. When this transformer fails, the entire control system goes dark: the thermostat loses power, no signals are sent, and the system will not heat, cool, or respond in any way. A failed transformer is often mistaken for a bad thermostat or control board, making correct diagnosis critical before replacing other components.

• Specs: 60 VA power rating | 115/208/230 VAC multi-tap primary | 24 VAC secondary | 50/60 Hz | Foot-mount configuration | OEM Part No. HT01AW229
• OEM vs Generic: This is a genuine Carrier Factory Authorized Part. OEM transformers are wound to exact VA ratings and insulation class, ensuring stable 24V output under full load. Generic alternatives frequently underperform under high-demand conditions, causing nuisance lockouts or premature failure of downstream controls.
• Install difficulty: 2/5 — Disconnect power at the breaker before beginning. Tools needed: flathead and Phillips screwdrivers, wire stripper, multimeter (to verify 24V output post-install). Label or photograph all wire connections before removal. The multi-tap primary must be wired to match the actual line voltage present at the unit.
• Warranty: 1-year OEM factory warranty. In stock and ships same business day from our warehouse.
