Every kitchen these days is dependent on one appliance and that is the microwave. A microwave does several tasks that you would have otherwise done on the flame or gas. Thus it makes things easier for you by cooking or heating food through microwaves or electricity. But in some cases, your microwave may stop working but still have power. In such situations, you may need to check the main cause or reason and then approach the problem with a suitable solution. The following are the main causes of microwave not working but has power.
1. Problem with the line fuse
The first and main cause of microwave not working but has power is an issue with the line fuse. If more than required current flows through the microwave circuitry then the line fuse will blow. To find out whether this is the main cause, you can make use of a multimeter for continuity. If there is no continuity then you will need to replace it. You will also need to find out the reason why the fuse blew in the first place. It is better to contact a professional if you wish to replace the fuse or any other part for that matter.
2. Problem with the main control board
Another potential cause of microwave not working but has power is a problem with the main control board. Sometimes the main control board may become defective but before you check the main control board, you will have to check all the other parts first. Once you have made sure that the connections, wirings and other parts of the microwave are working fine, only then should you check the main control board. The board can be checked by first accessing it and then using a multimeter. If it comes out to be defective, you can replace it.

3. Problem with the thermal fuse
Another problem that can come up in a microwave is problem with the thermal fuse. The thermal fuse cuts off power to the appliance when it gets overheated. If you wish to find out whether the thermal fuse has blown or not, you can use a multimeter. If you find that there is no continuity, then you may need to replace it. However if there is continuity, you may have to check for other potential cause or reason.

Now that you know the main causes of microwave not working but has power, you can replace the part at fault so that the appliance starts working again. But one must remember that even after unplugging the microwave, a lot of volts of electricity still remains inside and trying to replace parts can lead to electric shock or current.
