Dream Cheeky will help you know How To Fix Overheated Microwave 2022: Things To Know
A computer technician brought this to my shop and explained that this microwave oven gets over heated. I had to ask, what do you mean by overheating? The best way was to show me what is really happening with it right there in my shop. He powered on the device and it was working fine. Then suddenly, it hit me; the fan was not working, I usually hear the sound of fan running but at this time, I could not hear it. I powered off the device and took it apart.
It is a medium size microwave oven and as you can see, it is Graetz made.
On the inside, it is just like any microwave oven although it says on the back it was made in China.
This is an outside view of the back of device where the fan sits. I just wanted to make sure that the air flow was not blocked with dirt. This fan is supposed to take and direct the flow of air from outside to inside to cool off the magnetron.
I took the fan out along with its plastic holder to test the coil on it.
As I was about to test the coil of this fan when I noticed the breaking of the coil windings and that was enough indication for me that the fan is out of order and it has to be replaced with a new one.
The parts of the microwave oven are hard to find. The only way to get them is from an old microwave oven that is usually found in the junk yard. I made a habit of collecting such parts in my workshop. When a microwave oven comes to my shop and the owner finds it too expensive to repair, I just buy the whole thing and then take them apart.
I sometimes get them for free. I throw away what is bad and keep what is good which saves me a lot of hassle driving the whole way to the junk yard and of course make more money of it.
I mounted the new fan on the plastic holder and then I attached to the body of the microwave oven. I turned the microwave oven on and at this time, the fan was running and the air was flowing smoothly from outside to inside keeping the magnetron cool and nice.
I did some testing on it and it passed with high stars. Mission accomplished.
