How do I Fix a Microwave Oven Power Problem. That will not turn on?


Oct 18 2019


The microwave is an essential everyday appliance that serves several purposes in the kitchen and helps us not only to cook but also to heat. It is a device that is used several times a day and, due to this constant use, may begin to show signs of wear or damage from time to time. If you are someone who faces the problem of lack of energy in the microwave and does not work, you must first understand the possible reason behind this and then find a solution.

Below are some ways to fix the problem of microwave stopped working/No Power

  • Door Switch
  • Ceramic Fuse
  • Thermal Fuse
  • Door Latch Assembly

Door Switch:

If your microwave does not start, you may have a problem with a door switch. The door switches often referred to as primary or secondary interlocking switches provide power to the various components in the microwave when the door is in a closed position and interrupt power when the door is open. Sometimes it is possible that when a door switch fails, the screen and controls may appear normal, but the oven does not work. The interlocking switches are located inside the cabinet and are activated by hooks or latches on the door. Unplug the unit and remove the cabinet. Interlock switches will have wires connected to terminals that are marked as common and normally open. You can check the continuity of the switches with a multimeter. With the actuator button pressed, you should see continuity between these terminals. If there is no continuity, it will be necessary to replace the switch. You should also verify that the door hooks fit properly in the switch actuator when the door is closed and adjust or replace it if necessary.

Ceramic Fuse:

The other problem that the microwave stopped working could be the ceramic fuse. If the microwave is not starting and the display is also blank, the ceramic fuse may be defective. This is the part responsible for protecting other parts from fluctuations and when it fails, and then the microwave also fails. Unplug the microwave and then access the fuse from inside the cabinet that is near the power cord. To verify the continuity of the ceramic fuse, use a multimeter. If continuity is not observed, you may need to replace the fuse.

Thermal Fuse:

A problem with the thermal fuse or cut could be the reason why your microwave does not turn on. Thermal cuts, also known as thermal fuses, help prevent the oven from overheating. When the thermal cuts fail, your microwave will not turn on as a safety measure to prevent it from getting too hot. Take this opportunity to also verify that the cooling fan is working and is not causing the microwave to overheat when the airflow is cut.

Door Latch Assembly:

If your microwave does not turn on, you may have a problem with the door latch assembly. The door latch assembly generally consists of two hooks that protrude from the door and fit into the door switch bracket that is mounted on the microwave frame. The hooks will contact the door switches to provide power to the controls and will also be attached to the support to keep the door closed. The latch assembly is usually made of plastic and generally has a spring connected to provide downward tension to keep the hooks engaged. If any of the hooks are broken or have no spring tension, the switches may not be activated. If this happens, the oven will not turn on and you may need to replace the assembly. Unplug the unit and remove the inside door panel to access the door latch. The inner panel is normally held by plastic pins and care must be taken to remove it.
