How to Test and Replace a Microwave Ceramic Fuse
Tools:
mmeter
Along with glass fuses, ceramic fuses are among the most commonly used fuses in household electrical appliances. This includes microwave ovens. A microwave oven is prone to short circuiting caused by severe voltage fluctuations.
Presence of a ceramic fuse ensures that an electrical surge is unable to harm the inner components of the microwave. Unlike glass fuses, ceramic fuses are filled with a special filler material. Usually, this is sand. When a violent electrical current tries to surpass the fuse, the overheated sand within the fuse breaks through, breaking the electrical circuit. This is because sand is a very poor conductor of electricity. Further, sand-filled ceramic fuses have a higher breaking point since sand can sustain the extra heat to a greater extent. However, while protecting the microwave oven, a fuse tends to get blown or it melts. Such a ceramic fuse needs replacement. This can be easily done using the following information.
Step 1 - Getting Started: Basic Precautions and Locating Ceramic Fuse Holder
Get started by wearing rubber gloves. Ensure the surface around the microwave is completely dry. Remove all the connecting power cords of the microwave. Ideally, you should turn off the main electrically supply. If the room is a bit dark, use a flashlight. Turn the microwave oven so that its rear is accessible. Here, you are likely to find a metallic plate secured with screws.
Some of the older models might have a dedicated fuse box located just below the bottom plate of the microwave. Use a screwdriver to loosen these screws and remove the back-plate. Trace the power cord that will lead you to the main electrical connections. Usually, the microwave fuse holder is located in vicinity of where the power cord is attached internally.
mmeter. This is necessary for ceramic fuses since they don’t develop a blackened appearance like blown, glass fuses.Step 3 - Procuring New Microwave Ceramic Fuse
Some of the fuses may not carry a voltage or amperage labeling. This makes it difficult to decode the appropriate replacement. It is better that you take the blown fuse to an electrical supply store to get an exact replacement. Ideally, you should buy a couple of extra fuses for the near future.
Step 4 - Replacing Microwave Ceramic Fuse
You don’t need tools to install the new fuse. Simply insert it within its dedicated slot in the fuse holder. If the fuse doesn’t seem to fit in its slot, clean the fuse holder and fuse slots. For this, use a dry cloth wrapped around the tip of a flat head screwdriver. Use the covered tip to gently scrape the fuse surfaces. Re-insert the replacement fuse. Secure the microwave back cover and tighten its screws.
