Description
The Trane CNT6628 Control (commonly superseded by part number CNT06628) is a genuine OEM power supply control board used in many Trane and American Standard HVAC systems to regulate the 13.8 V DC supply that powers low‑voltage controls and circuits within the unit. It ensures that sensitive electronics receive stable power, protecting components and supporting reliable operation of your heating and cooling system.
