What To Do When Microwave Fan Won’t Turn Off
Ever find yourself scratching your head because your microwave fan won’t turn off? Let’s chat about it in simple terms. Microwaves are a kitchen superhero for quick meals, but that never-ending fan buzz can be a bit much. This article is your guide to figuring out why.
First, it might be an easy fix – perhaps you’ve been giving your microwave too much action. Even machines need a break sometimes! Or, it could be a case of the thermostat or control board acting up.
Your kitchen might be getting too hot, making the microwave feel a bit stuffy. Just like us when it’s too warm! And if there’s gunk blocking the air or grease filters, that might be the reason for the fan frenzy.
Oh, and sometimes the fan motor just throws a little tantrum. It happens to the best of them. The good news? You’re not alone in this microwave mystery.
Let’s figure out why your microwave fan won’t turn off and give it the breather it deserves.
Reasons Your Microwave Fan Won’t Turn Off
The microwave might be overused.
Sometimes, if your microwave fan isn’t working well, it might be because you’re using the microwave too much. Microwaves have a kind of internal thermostat that turns off the fan when everything inside cools down. It’s like giving your microwave a break to cool off. This is especially important if you’ve been using it for 5 to 10 minutes or more. If you keep heating things up one after another without a break, your microwave might need more time to cool down properly. So, it’s a good idea to let it take a breather.
The microwave could be overheating from problems with the control board or thermostat.
Microwaves have a temperature controller inside called a thermostat. This thermostat makes the fan stop when the microwave cools down enough. But, if this thermostat isn’t working right, the fan might keep running even when the microwave is cool.
Now, there’s also a thing called the control board, which is like the brain of the microwave. It controls the fan and sits inside with the buttons you press on the outside. If the connections in this control board aren’t good, the fan might not stop when it should or even turn on when you open the microwave door.
If your microwave feels too hot, even after a short time, it could be a sign of a problem with the thermostat or control board. When things like this happen, it’s best to get help from someone who knows about fixing appliances. They can figure out what’s wrong and make your microwave work properly again.
If the kitchen is too hot or the microwave doesn’t have proper ventilation, the microwave may not be able to cool.
If the oven has been on for an extended period, with several pots cooking on the stove, the overall temperature in the kitchen will rise. This can pose a challenge for the microwave to cool down after use, leading to the microwave fan automatically turning on or running for an extended time.
It’s also essential to take into account the microwave’s placement in the kitchen. Microwaves benefit from having small gaps between their back, top, and sides and the surrounding walls or cabinets, allowing proper airflow through the microwave air vents.
In some instances, over-the-range microwaves might be installed too close to the stovetop. When the stove or oven produces heat, it may rise and activate the fan beneath the microwave. The International Residential Code recommends a 30-inch distance between the top of the microwave and the stovetop, though manufacturers may provide different installation instructions.
Clogged air or grease filters can keep a microwave fan running.
Microwaves above the stove usually have two filters: one for smells and one for grease. If these filters get dirty, your microwave might not work as well, and the fan could run more.
The air filter, often under the top vent, is usually made of mesh or charcoal. And the grease filter, found at the bottom, helps stop gunk from building up. You can take both filters out and clean them with soap and water. For the grease filter, using warmer water can help if there’s a lot of oily stuff. If cleaning doesn’t work well, you might need to get new filters.
The fan motor could be malfunctioning.
If your microwave fan just won’t stop, it might be because the fan motor is acting up. This motor is what makes the fan go round. Sometimes, it can have issues, but a repair technician might be able to fix it. If the motor is too damaged, you might need to get a new one to solve the problem.
An appliance repair technician can take care of microwave issues.
If your microwave is acting up, like the fan not turning off, there are some things you can try, such as letting it cool down or cleaning the filters. But, if it’s a tricky problem inside, it’s best to call a local appliance repair person. They’re experts at fixing parts that might be causing issues.
Microwaves usually last about seven years, but if you use them a lot or don’t take good care of them, they might not last as long. An appliance repair person can help determine if your microwave can be fixed or if it’s time for a new one. So, don’t hesitate to reach out if you’re having problems with your microwave.
How Do You Reset The Fan On A Microwave
- Manually Turn Off the Fan: Look for buttons like “Options” or “Control Setup” on your microwave. Press these buttons and find “Vent Fan” in the menu. Turn it off and wait for about 30 minutes before turning the fan back on.
- Give Your Microwave a Clean: Sometimes, all your microwave needs is a good cleaning. If you don’t clean it regularly, the fan may overwork. Clean it up, especially the air vents, and see if that solves the problem.
- Unplug and Reset: If the fan still won’t stop, try unplugging your microwave for about 30 minutes. Plug it back in; this simple action might reset the fan and let your microwave cool down.

Fans of microwaves from brands like Bosch, Kenmore, Samsung, GE, Whirlpool, Frigidaire, Maytag, and LG can sometimes act up. But don’t worry; the steps mentioned above can help, no matter what brand. If problems persist, it might be a good idea to seek help from a professional.
In conclusion, troubleshooting a persistently running microwave fan, especially when the “Microwave Fan Won’t Turn Off,” involves practical solutions such as giving it a break, making manual adjustments, or thoroughly cleaning it.
