What should I do if my microwave oven won't start?

Check that the power cord is plugged in tightly — unplug it and plug it back in after 10 seconds. Also verify that the fuse has not blown or the circuit breaker has not tripped, and test the outlet with another appliance to confirm it is working. Additionally, make sure the door is closed properly, as the oven will not start if the door is not fully shut. (Page 15)
