another carrier VFD failed, or is it? blower was not running on arrival, and I suspect the drive had a fault. I did not verify this and then found the fuses not blown. on reset, the drive started and ran. I decided in the end to bypass the drive to prevent another problem and wire in a contactor to control the motor.
