Microwave wont turn ON
Microwave wont turn ON. Microwaves are one of the most commonly used appliances in many kitchens across the world. They can be used to cook pasta, soup, and even whole dinner plates.
You can also use them to make tea or instantly prep a hot breakfast. So, when your microwave breaks down, it’s only natural that you would want to try your hand at repairs.
However, you should be aware that microwaves are surprisingly complex machines, despite their small and affordable size.
There are many different ways that a microwave can go wrong, and each issue has multiple possible causes.
Therefore, it is often best to seek the help of an experienced appliance technician when it comes to replacing tightly packed electrical components within a microwave.
Microwave wont turn ON
We will discuss here the causes of not turning the microwave.
Ceramic Fuse
The ceramic fuse is a microwave part that can often cause a blank and unresponsive display.
This part is responsible for protecting other microwave components from power surges, and when it fails, it causes a loss of power which means your microwave won’t work.
If you know what caused the fuse to fail, such as opening or closing the microwave door, you can test the door switch to see if that is the issue.
If you’re not sure why your microwave’s fuse has blown, it’s a good idea to test other parts of the microwave such as the magnetron, high voltage diode, capacitor, and transformer.
By doing this, you may be able to pinpoint the cause of the problem and fix it.
Door Switch
One potential reason your microwave isn’t starting could be because of a malfunctioning door switch.
The door switch, sometimes called an interlock switch, sends signals to other parts of the microwave to start heating when the door is closed and to stop when the door is open.
If the door switch isn’t working, everything else might look like it’s in working order but the microwave won’t actually heat up.
Thermal Fuse
A potential reason your microwave isn’t starting up could be related to the thermal fuse or cut out.
These components, known as thermal fuses, help prevent the oven from overheating. If the thermal fuse fails, then your microwave won’t turn on to avoid the appliance getting too hot.
While you’re at it, you should also check if the cooling fan is running properly. If it’s not, then it could be causing the microwave to overheat by not allowing enough airflow.
FAQs
What should you do if your microwave suddenly stops working?
If your microwave isn’t working, one potential issue could be a blown fuse. To check if this is the problem, first unplug the microwave.
Next, locate the fuse inside the cabinet near the power cord. To test whether or not the fuse is continuity, use a multimeter. If there is no continuity, then you will likely need to replace the fuse.
How long does a microwave last?
The average lifespan of a microwave oven is around seven years, but this number goes down with heavy use and lack of proper maintenance.
If you have a large family that relies on the microwave to heat up food, you may find yourself replacing it every four or five years.
Conclusion
Microwaves are a convenience that we can’t live without, but that doesn’t mean they are immune to breaking down. It’s important to know how to fix a microwave if it should happen to stop working. A quick internet search will provide you with a few different solutions to try, but if you are still unsuccessful, it may be time to call a professional.
