Reasons and Solutions: Why Does My Range Hood Fan Keep Running?

As we have narrowed down the highest probable reasons, it’s time we check out the solutions. So get your handyman belt/box on the ready and keep on scrolling. 

1. The Switch Is Broken

Every home has a range hood from the beginning. And chances are you’ve been using it for many years and it’s serving you well. 

As it has been running for a long time, the switch tends to wear off. It’s a natural process of using something. 

Solution: If you have any electrical knowledge, you can replace the switch with ease. Turn off your range hood and proceed on removing it. Take it with you to the electrical accessory shop or home depot for a perfect match. And then replace it. 

If you don’t have any idea, we suggest you call your expert handyman. 

2. The Circuit Board Is Damaged

The more serious matter is your hood circuit board getting destroyed. But it is not uncommon. As the hood takes up all the heat, grease, and fume, it is understandable. Also, moisture buildup can also damage the circuit. 

Solutions: Even if you have some electrical knowledge here and there, it is best to leave it to the pro. As it requires taking apart almost the whole range hood, it will be a frustrating process. Not to mention the digital volt meter checks, taking out the old circuit and replacing it with a new one, and finishing up by putting it together. So call the professional on this one. 

3. The Fan Motor Is Unresponsive

A range hood is exposed to a lot of dust, fume, humidity, and grease. These sometimes overheat the fan motor or even cause the circuit to malfunction. And no matter how many times you turn the switch on and off, it won’t just turn off. 

Solution: Unplug your range hood immediately. As this can be the fan’s motor or the circuit itself at fault, calling a professional to inspect is the best move. 

4. Wiring Problem From the Factory

Although today most of the factories are automated, and there is a very low chance of error, it still happens. Light-fastened, improper shouldering wires can be a silly mistake in some range hood units. Which ends up with your fan not turning off. This happens for newly bought products most of the time.

Solution: Most appliances come with a service warranty which is free. We suggest you contact the manufacturer and claim it. If there isn’t any, you always have the handy guy a call away. 

Pro Tips:

• Clean your range hood at least once every 3 months.
• Remember to clean the switch, the fan, and the lights accordingly. 
• Grease buildup can cause the switch, circuit board even the fan to malfunction. 
• Always be cautious while working with electrical components and remember to turn off your main circuit breaker.
