If your fan isn't working, the first thing you should do is check to see if it's plugged in. Sometimes people assume a fan is broken when it's actually just not turned on. If the fan is plugged in and still not working, you may need to replace it. Fans come in different sizes, so make sure you get the right size replacement fan for your model. You can usually find this information on the manufacturer's website or on the fan itself. Once you have the right size fan, follow the instructions that came with your new fan to install it properly. Be careful not to pinch any of the wires or cables while installing the new fan. And always turn off power to the appliance before
There are a few potential problems that could be causing your fan to not work. The first thing you should do is check the fuse in the plug. If it's blown, then replace it. If the fuse is okay, then the next step is to check the power supply. Unplug the fan and plug something else into the outlet to see if it's getting power. If it is, then you know there's a problem with the fan itself and you'll need to replace it. If you're not comfortable doing this yourself, or if you're not sure how to go about it, then I would recommend taking it to a professional who can help you get your fan up and running again.
