Frigidaire Professional Microwave W/no Power

A dishrag was heated in my microwave. Although it did not start a fire, it did smolder in the microwave for a while causing some smoke but no heat damage to the interior of the oven. It did not trip the circuit breaker. There is still power to the electrical outlet but there is no power going to the microwave. Could it have blown the interior fuse? Any help for me? Microwave is in excellent condition and this human error is the first problem in five years of service. PLEASE HELP!!!
