Microwave not working

  • Door switch
    There are many reasons why your microwave oven does not turn on, one of which can be a faulty door switch. A door switch, known as a lock switch, signals to other microwave components to start the power supply when the door is closed and stop when the door is opened. For this reason, everything else can appear in working order, but the microwave will not start to heat up. To access the door switch or the lock switch, turn off the microwave oven and remove the cabinet. The switches have terminals designated C for general and NO for normally open. Check each terminal with a multimeter to ensure continuity. If at the time there is, then it means that the switch is working. If there is no circuit, replace the switch. You can also take this opportunity to make sure that the door hooks work correctly.
  • Ceramic fuse
    If your microwave oven does not start and the display is empty and does not respond, the problem may be related to the ceramic fuse. This part protects other microwave components from power fluctuations and leads to a total loss of power when it fails, that is, your microwave oven will not work. To access the ceramic fuse located inside the cabinet next to the power cord, first turn off the microwave oven. Use a multimeter to check the integrity of the fuse. If you are aware of the cause of a fuse failure, such as opening or closing a microwave door, you can also check the door switch to make sure it works. If you do not know the cause of the fuse failure, you can test other microwave parts, such as a magnetron, a high voltage diode, a capacitor and a transformer.
  • Thermal fuse or cut-out
    The problem with a thermal fuse or cutout can be the reason that your microwave oven does not turn on. Thermoswitches, also known as thermal fuses, help to keep the furnace from overheating. When the heat outputs do not work, your microwave oven does not turn on as a precaution so that it does not heat up. To access the thermal switches, first turn off the microwave oven, and then remove the cabinet. After you find the thermal fuse, disconnect its wires from the terminals. Use the multimeter to check for continuity and replace the thermal cutouts if there is no continuity. Take this opportunity to also check if the cooling fan is working, or to cause the microwave to overheat, shutting off the airflow.
  • Door Latch
    Your microwave oven may not start due to a problem with the door latch. Most of the door latches are made of plastic hooks that stick out of the door and lock the door switch when the door is closed, signaling the rest of the controls to turn on the microwave. If the hooks are damaged or do not have tension due to worn springs, the switch will not click, which means that the microwave oven does not turn on. To gain access to the door latch, first unplug the microwave oven from the power source and remove the inner door panel that is held in place with plastic plugs. Inspect the door latch and replace it if it is damaged.
