At first, a microwave seems less important than a fridge or a washer. In fact, the owners understand the full nature of their loss when the microwave breaks down. It takes more time in the morning to make breakfast, no chance to heat something tasty up after a hard working day… A sad scenario! It doesn’t really matter what brand you use, all of them may break down one day. When a microwave won’t stop, there is a popular situation that can help you accurately diagnose the problem. If you open the microwave door and your microwave oven continues running the problem may be with your door switch. A door switch supplies the microwave with the power, and if the continuity should be broken once, the door is open. To test if you have a problem with the microwave door switch take off the cabinet and unplug the power cord. Use the multimeter to test the wires of the switch. There should be continuity when the door is closed, but not when it is opened. Most of the time you will have to replace the door switch in case it is broken. Unfortunately, the issue can concern other parts like a control board or control panel. While the switch is a little more difficult to recognize, it is easier to remove and replace than a control board. The most difficult part is reaching it and finding the screws that need to be removed in order to unmount it. Unlike the control board, if the microwave is running with the door open, it can only really mean a faulty switch so there isn’t really much need to test it. Of course, you may simply invite a technician to diagnose the appliance for you. It is a preferable way as a professional assistant will investigate the deal the most efficiently and help with purchasing and replacing the broken part. Take care of your appliance and conduct a regular maintenance visit in time.
