So what exactly is a fuse, and how important is it in a microwave? Let's find out.

What Is A Fuse And Its Function?

Fuses function like mini circuit breakers in appliances. Besides protecting the device, they act as security measures to avert any dangers to people. Fuses have a bit of wire strip that sends electricity, which dissolves when it notices an overcurrent.

Microwaves typically contain several kinds of fuses for secure function. The primary or line fuse cuts the electricity flow if too much current passes through it, while the thermostat fuse stops electrical flow if the fuse gets too hot.

The fuse is a conductor with a wire portion that quickly dissolves and breaks the connection with the circuit if there's a current overflow. The fuse operates as a wiring and apparatus protector if something goes awry.

Why Is A Thermostat Fuse Necessary For A Microwave?

The thermostat fuse's job is to safeguard microwaves from overheating. The microwave will stop functioning when overheating activates the thermal fuse. Don't ever disregard a microwave's fuse, because there's a big chance that you can set your microwave on fire.

How Do You Tell If A Fuse Is Blown?

You must look closely to check if your microwave's fuse has blown. Take the fuse out of the holder cap and examine the fuse wire. You should replace the fuse if you find a metallic or dark smudge inside the glass or a fissure in the wire.

What Happens If The Microwave Fuse Is Blown?

Microwave fuses blow for several reasons. The high-voltage capacitor inside may have shorted out, a screw may be loose, or the door switch could be defective.

When a fuse blows, your microwave usually won't heat food. It's likely that the light bulb or your entire microwave will not turn on.

How Do I Change The Fuse In My Microwave?

Changing a blown or broken microwave fuse is easy, but you must still exercise precaution. Here are the eight steps in changing your microwave fuse.

  1. Ensure that the microwave is unplugged from the power source.
  2. Unscrew the vent grille or access the fuse without uninstalling the microwave (it depends on the placement, make, and unit).  
  3. Unclip and remove the microwave fuse.
  4. Use a multimeter to test for the continuity of the microwave fuse.
  5. After verifying that the fuse is the cause of a non-working microwave, you need to replace it.
  6. Buy a replacement fuse that's similar to the damaged fuse you extracted.
  7. Reassemble, replug, and turn on the microwave's power.
  8. Check if the new fuse works by putting in a cup of water and microwaving it for thirty seconds.

If you continue to experience a blown fuse, you may have installed the wrong one or need to replace a different microwave part. We recommend you call a professional technician to further check and fix your microwave.
