We just had a brand new furnace installed In November 09. Shotly after we noticed a vibration. The upper motor (induction motor) is mounted on a plastic box and as the motor runs the box vibrates. I place my hand on the box, vibration stops, I place side pressure on the motor vibration stops. All mounting screws are tight. Is it likely the motor has an imbalancd problem?:confused
