microwave oven problem and solution

The most important appliance that every kitchen need is a microwave oven. A useful appliance for reheating food quickly and conveniently. But along with lots of advantages of microwave ovens, there are some downs and problems in it. In this article, we will deal with different common problems along with solutions that you can face with time. So let’s dive into the detail.

Not heating food 

One of the common microwave oven problems is not heating food properly. Scientifically, the microwave oven produces electromagnetic waves that penetrate food and result in cooking. However, if your microwave does not heat food properly, the reason behind this problem is Magnetron, capacitor, or diode. They are responsible parts for the generation of microwaves inside the oven. If any of these parts fail, the microwave will not be able to heat up food. So, it is good to deal with this problem on time to prevent further damage. 


If your microwave does not heat food properly then look for the following things to fix.

  1. Check the oven door and fully close it, because it may be one of the reasons.

So the first step is to identify the main reason. 


As we already mentioned the reason, Some of the possible solutions to the problem are given below:

  1. Check the power source, whether it is a plugin or not, and whether the circuit breaker is not tripped. 
  2. Then try to reset the oven by unplugging it for a few minutes and then plugging it back. If the issue still persists then the third one is the reason.
  3.  The third reason is faulty components like a control board, blown fuse, or loose connection. Identify the component, and repair or replace it.   

The microwave shuts off after a few seconds

Another common error faced by many users is Shutting off the oven after a few seconds.

Microwave ovens are a convenient and time-saving appliance in any kitchen, but they can experience problems like any other electronic device. This can be caused by a variety of factors, including a faulty door switch, a defective thermal cut-out, or a malfunctioning control board.


Now its time to solve this problem, The following are the solutions

  1. The first step to deal with this issue is to check the door switch. A faulty door switch can cause the microwave to shut off as a safety measure. Make sure the door is properly closed and the switch is functioning properly.
  2. The second reason is the defective thermal cut-out. The thermal cut-out is a safety component that shuts off the microwave if it overheats. Check if the thermal cut-out needs to be reset or replaced.
  3.  If the control board is malfunctioning, it can cause the microwave to shut off prematurely. Try resetting the control board by unplugging the microwave for a few minutes and plugging it back in. If the issue persists, then it needs to repair the control board.   done

The door not closing properly
