Microwave oven stopped working. Timer works and counts down but micro wave does not turn and turn

Question

Timer works and counts down but micro wave does not turn and turn table does not spin. Fan works. Light works. Is this common? Can it be fixed? Should I buy a new one?

Microwave oven does not work and fan does not run, but clock, timer and ligh operate. Door contacts seem to be OK and fuse seems OK since or light and clock operate.
