When the microwave oven power does not work fault, should be in accordance with the following overhaul process for detection:

1, detection of the protective device, the protective device is mainly a fuse, thermostat, door switches, monitoring with the linkage switch, etc., such as the discovery of the above components have been damaged, it should be replaced in a timely manner.

2, test the control device, in the case of the protection device is normal, the microwave oven still can not enter the working state, most of the cases is the control device failure. As the microwave oven control device has a mechanical and computerized two, therefore, should be analyzed according to the actual failure.

Mechanical control devices only need to detect the timer and its bracket can be, while computerized control devices need to control circuit components, microprocessor detection.
