OEM Carrier Control Transformer 60VA 115/208/230V–24V for Model PH13NR036000AFAA

This is the factory OEM replacement control transformer for the Carrier PH13NR036000AFAA heat pump system. The control transformer steps down high-voltage supply power (115, 208, or 230 VAC) to the 24 VAC signal that powers your thermostat, contactor coil, and all low-voltage control circuits. When this transformer fails — due to a shorted control board, failed contactor coil, or simply age — the entire control circuit goes dead: the thermostat goes blank, the system won't respond to any commands, and no heating or cooling is produced. Replacing it with the correct OEM unit restores full system operation immediately.

• Specs: 60 VA power rating | Primary voltage: 115 / 208 / 230 VAC | Secondary voltage: 24 VAC | Foot-mount design | 50/60 Hz operation | OEM Part Number: HT01AW229
• OEM vs Generic: This is a genuine Carrier Factory Authorized Parts (FAP) transformer wound to exact VA and voltage tolerances. Generic transformers often run undersized VA ratings, causing overheating and nuisance trips when multiple control loads are present. OEM protects your compressor contactor and control board investment.
• Install Difficulty: 2/5 — Disconnect all power before servicing. Tools needed: flathead and Phillips screwdrivers, multimeter, wire nuts or spade terminals. Always verify primary and secondary voltages with a multimeter before reconnecting. Check for shorted loads that may have caused the original failure before powering up.
• Warranty: 1-year OEM manufacturer warranty. Ships same business day from our warehouse — order by 3 PM local time for same-day dispatch.
