Troubleshooting: Failed Range Hood Parts

Range hoods are a critical part of a modern kitchen, serving to keep the kitchen's air clean and dry, but common range hood problems plague us all. If your range hood is not working, you may want to try to fix it yourself before you make a service call. But how to fix a range hood? The experts at Appliances Connection have compiled this list of common range hood problems that you may be able to fix by yourself.

Your Range Hood Won't Turn On

If your range hood won't turn on, the first step is to check and reset the circuit breaker that's connected to it. If the breaker hasn't been tripped, unplug the range hood and check for any obvious wiring issues, or anything blocking the fan or motor. Fixing the problem could be as simple as replacing the switch.

The Fan Doesn't Clear Air From Your Range

There are a lot of mechanical and electric issues that can cause poor air suction in your range hood. First, unplug the range hood and inspect the fan blades. If the fan blades are bent, broken, or missing, you'll have to replace the fans. Also check the fan motors to make sure they're connected properly, and make sure to clean your range hood's ducts to get rid of any blockages that may be reducing the flow of air inside it.

If everything in your range hood is working properly, and you still aren't getting enough suction power, you may need a range hood with a higher CFM (cubic feet of air per minute) rating.

Your Range Hood Is Accumulating Moisture

One of the primary functions of a range hood is to help keep the air in your kitchen dry by sucking moisture away from you as you cook. If you get a mini rainstorm in your kitchen every time you boil water, something is definitely off with your range hood! The primary culprit here is lack of insulation around your range hood's venting. If you can replace or shore up the ducting with proper insulation, you'll have a much drier cooking experience. You should also check the dampers of your range hood to make sure they are operating as intended.

Your Range Hood Makes Strange Noises

If your range hood is making strange noises when you turn it on, the first step in troubleshooting the issue is to unplug the range hood. Then check the fan to make sure that nothing is blocking it. While you're at it, you should also clean your range hood's filter, as blockages in the filter can cause air flow to back up and choke the fan. Finally, check any belts or gears in your range hood to make sure they can move smoothly, without stopping.

This is often one of the easiest common range hood problems to fix. If your range hood has a replaceable bulb, check that to make sure it hasn't burnt out. You can also check the control board for signs of overheating (such as burn marks or melted spots). Always make sure to unplug the range hood before you take a look at any parts or replace the bulb!

Related Questions

Do range hoods have fuses?

Most range hoods have thermal fuses that trip if their temperature gets too high. You can test the status of this fuse using a multimeter, or call a service professional to check it out.

How often should a range hood be replaced?

Range hoods are incredibly robust and long-lasting appliances. In general, they can last more than 10 years of regular use.

How can I make my range hood more powerful?

While there's no way to increase the CFM rating of your range hood without replacing it, you can keep your range hood well-maintained and its ducts and fan blades clean. This increases airflow throughout your range hood and improves its suction power. On the flip side, several brands such as Thermador and Faber sell blower kits separately from select models. That means if you're fairly certain about the CFM you need and it turns out to be wrong, you can potentially swap it with a weaker or stronger blower.
