A grinding or rumbling turntable on an M2240SC is usually the roller ring rather than the motor, and it is one of the few microwave complaints an owner can investigate safely: the tray and ring lift straight out. A ring with a cracked or missing roller makes exactly that noise, and replacing it is inexpensive. If the ring is sound, the coupling or motor is next in line.
