Samsung Microwave Blows the Fuse [How to Fix]

If your Samsung microwave blows the fuse repeatedly, there is something really wrong with it. It’s better to attend to the problem first before replacing the fuse. In this article, we are going to show you what to do when your Samsung microwave blows the fuse and how to replace it.

Samsung Microwave Blows the Fuse When Door Opens – Causes

Before we get into how to check and replace the fuse in a Samsung microwave, let us talk about the causes.

The Outlet

The reason your Samsung microwave blows the fuse may be because of a bad outlet. To check whether this is the case, unplug the microwave from the outlet. If you see that around the outlet looks a bit melted, call an electrician to check and replace the outlet. After replacing the outlet, plug the microwave back and use as you normally do. If it doesn’t work, read on. Note that if the blown fuse hasn’t been changed and you fix the outlet and the other problem we will get to, the microwave still won’t work.

Door Interlock Switches

This is another cause of a blown fuse. To check and replace the door interlock switches, do the following…

Step 1: Unplug the microwave.

Step 2: At the top of the microwave, there will be two screws (one on the right and one on the left), take them out using a screwdriver.

Step 3: Open the microwave door and remove the front grille.

Step 4: Afterwards take out the three screws at the right (there will be one at the top right, one in the middle, and the last one below that).

Step 5: Next, raise the control panel up and gently pull it out. You will see three switches at the left side of the microwave.

Step 6: At the top left there will be the first switch with something yellow sticking out of it. Below that, there will be a white switch, and the last switch will be a black one.

Step 7: Disconnect the three switches. As you disconnect them, remember what color goes where because connecting a different type of switch in a different place could cause problems.

Step 8: Test each switch by pressing the little button on top. If there is a strong click when you press each one, the switches are good, if not, you will need to replace the bad switches. When getting new switches, ensure that the one you buy is the same type as the bad one.

Step 9: After buying a switch, connect it to the place the previous one was.

Step 10: Screw back the control panel.

Step 11: Assemble the microwave back.
