One of the most used appliances in your kitchen is a microwave oven. When it stops working, or working incorrectly (like the display panel is flickering), we recommend you to fix the appliance. In some cases you can repair your microwave by yourself, without calling a technician, if you will be careful. When the display panel is flickering, you must check the microwave fuse. You can use a multimeter to test the part for continuity. A continuity test will determine if a continuous electrical path is present in the fuse. Before you begin, make sure the microwave is unplugged, but since high voltage capacitors used in microwaves may retain a charge even after the oven has been unplugged, it is recommended to discharge the capacitor before servicing.
If you determine that the fuse is faulty, the next step is to replace the part. As with testing, be sure that the microwave is unplugged before beginning the repair. The first step of the procedure will depend on your model of microwave. If your fuse is located behind the control panel or vent grille, you may be able to access it without removing the microwave from its installation. You will need to remove the grille or control panel to access these fuses. If you cannot access the fuse you need from behind these panels, you will first need to uninstall the appliance. This can usually be achieved by removing 2 or more screws from the top of the microwave, then lowering it and lifting it off a mounting bracket. Set it on a sturdy surface, and then you’re ready to continue. Next, you will need to remove the outer cover to reach the internal components. Fuses are located in many places inside the microwave, including the top, side, and behind the vent grille. Using the wiring diagram can help you locate the appropriate fuse. Once you have located the fuse, remove any necessary wires and fasteners to free it from the microwave. To replace the fuse, connect any necessary wires to the new part, and secure it with any clips or fasteners if necessary. Replace the panels or covers and secure them with the screws. If applicable, carefully place the microwave on the mounting bracket, then align it with the cabinet, making sure the power cord is accessible through the top. Secure the screws, plug the microwave back in, and test the appliance to make sure it's working properly.
Process is done! Now your microwave oven must work as should. If you can’t fix the microwave alone, give us a call and appoint a visit at a convenient time!
