Microwave is essential everyday appliances which fulfils several purposes in the kitchen and helps us not just cook but also heat. It is one appliance that is used multiple times a day and due to this constant usage, it may start showing signs of wear and tear or damage once in a while. If you are someone who is facing the problem of no power in microwave and no working, then you must first understand the possible reason behind it and then find a solution. The following is a way to fix the problem of microwave stopped working, no power:

1. Problem with the door switch

One of the possible reasons for microwave stopped working and no power could be an issue with the door switch. A faulty door switch which is also often called as an interlock switch is the part which signals the other parts to turn on when the door gets closed and to stop when it is opened. To access the door switch, you will have to dismantle the cabinet but only after unplugging the appliance. There are two terminals which must be checked using a multi meter for continuity. If there is no continuity then the problem will be with the door switch and replacement might be needed.

Here are some of the recommended microwave door switches:

2. Problem with the ceramic fuse

Another cause of the problem of microwave stopped working, no power could be the ceramic fuse. If the microwave is not starting and display is also blank then ceramic fuse may be defected. This is the part which is responsible for protecting other parts from fluctuations and when it fails, then the microwave also fails. Unplug the microwave and then access the fuse from inside the cabinet which is near the power cord. To check the continuity of the ceramic fuse, make use of a multimeter. If no continuity is observed, you may have to replace the fuse.

We recommend following ceramic fuses for your microwave:

  3. Zephyr Slow Acting Ceramic Cartridge Fuse (Pack of 6) 5x20mm 250V (15 Amp)

3. Cut out or thermal fuse defects

If there is a problem with the thermal fuse, then this could be leading to no power in the microwave. Thermal fuses protect the appliance from overheating and to locate it you will have to remove the cabinet after unplugging the microwave. Disconnect the wires from the terminals and check the continuity using a multimeter. If no continuity is observed, replace the thermal fuse or cut out.

4. Problem with the door latch assembly

Another cause of the problem of a stopped microwave could be an issue with the door latch assembly. Door latch assemblies are made using plastic hooks which stick out of the door and signal other parts to power the appliance. If the hooks are not working or are damaged then the switch won’t latch properly and hence the microwave won’t turn on. Inspect the door latch and replace if the need be.
