Why does the fan on my microwave keep running?

Why does the fan on my microwave keep running?

All over-the-range microwaves have an automatic fan feature to help protect the electronic components, and also helps the cooking area get rid of excess heat. The built-in thermostat automatically turns the vent fan on if the unit is too hot, and will not turn off until the microwave is cool again.

How do you turn off the fan on a microwave?

How to Turn Off the Automatic Fan of a Whirlpool Over-the-Range MicrowavePress the microwave’s “Control Setup” or “Options” button so the microwave display enters setup mode.Scroll to the “Vent Fan” sub-menu and press “Enter/Start.”Select “Off,” then press “Enter/Start” a second time to turn the vent fan off.

What do you do when your microwave turns off?

You can try plugging something else into the outlet, like a night light, lamp, etc. If the outlet is getting power, the microwave may have overheated.

What happens when a magnetron fails?

Burned out terminals But if any damage happens to it will lead to the insulator breakdown. This insulator breakdown results in burning the terminal of the magnetron. It increases in every cooking cycle and leads to severer burnout.

Why does my microwave sound like a Geiger counter?

If your microwave is making noises like a Geiger counter, the sound is coming from the magnetron that produces the microwaves. The sound is normal and there’s no reason to be alarmed. If your microwave makes noises when it’s in standby that are somewhat loud or strange, something could be wrong with your fan run on.

Is a microwave magnetron dangerous?

Magnetrons can be incredibly dangerous, while you are safe from radiation when they are not powered, the ceramic insulators can contain beryllium oxide which can be fatal when inhaled. If Magneto is the enemy of the X-Men, the magnetron is the enemy of all lungs everywhere.

What happens if your microwave sparks?

Sparks in the microwave are usually caused by the microwaves hitting a metal object inside the appliance. Metals conduct electricity with lots of electrons which move freely. Sparks occur simply due to a build-up of charged particles which produce a concentrated electric field at the edge of the metal object.
