I have a couple of 1 HP Teco vfd's the one on a Grob band saw was speeding up and slowing down on its own up and down about 20 cycles but seems to be behaving lately, now the one my Bridgeport is becoming erratic . They are both about 10 years old . Any options beside replacing them, is this a common old age fault ?
