Health and indoor air quality concerns from gas stoves are a hot topic these days. Research from a 2022 Harvard T.H. Chan School of Public Health study found that homeowners with gas stoves may be exposing themselves to air pollutants, including benzene, xylene, and hexane, which can increase the risk for health problems including asthma and cancer. In April 2023, New York became the first state to ban installation of gas stoves in new construction buildings by 2026, with other areas following suit.

One way to improve indoor air quality in your home is to install a range hood above the stove to improve ventilation in the kitchen. These chimney-like appliances help keep the air in a kitchen safe and fresh by removing smoke, heat, moisture, fumes, oil, and cooking odors from the room. The range hood’s fans draw in the air directly above the stove up into the hood. So how do you properly operate and maintain a range hood? Let’s address this and some other common questions.

1. When should we turn on our range hood?

Range hoods should be turned on right before cooking begins to be as effective as possible in preventing odor, improving circulation, and capturing particles from grease and burnt food on the stove. Running the fan for several minutes before firing up the stove can help create suction and get the venting system going.

Do not wait until halfway through or after cooking is done to turn on the range hood because that will minimize its ability to get the job done. It is also important to remember that the low speed should be sufficient when using just one or two burners. If all the burners are on, then choose the high setting to maximize ventilation.

2. How long should we leave the hood on?

Let the range hood run for 10 to 15 minutes after you’re finished cooking to clear out any additional smoke, exhaust, and strong odors. Some exhaust fans have an auto-shutoff feature that turns off the hood after about 10 minutes. Do not run it much longer than that because long and frequent use can put a strain on the motor and wear it down more quickly.

Overall, do not leave the fan on for more than an hour or two while cooking. For those who cook for long periods of time, it is recommended to choose a high CFM range hood with a top-notch motor.

3. What’s the best way to clean a range hood?

With all that grease and grime splattering, it can seem like a challenge to keep the range hood nice and clean. As range hoods are often designed to be an attractive centerpiece in the kitchen, keeping a range hood clean helps it run smoothly as well. It is recommended to clean the range hood on a monthly basis.

To clean the range hood, first make sure that the stovetop and range hood are off. Invest in a degreasing cleaner and regularly wipe the inside and outside of the hood. Warm water and mild detergent can also be used with a cloth. Rinse well with water and dry immediately. While stainless steel polish can also help keep the range hood looking shiny, make sure to follow the manufacturer’s cleaning directions.

4. How do we clean the vent and fan?

It’s essential to keep the vent and fan clean. Check the vent leading from the hood to the outside on a regular basis since grease can build up inside that area. Build-up can prevent the vent from functioning properly and can even be a fire hazard.

On occasion, check the fan motor and bearings to make sure they have not been damaged by excessive humidity and grease. The blower wheel, which often collects dirt and grease, can be removed and cleaned with a degreaser. If this does not work, it may be time to replace the motor. If you are unsure about cleaning the vent and fan yourself, consider hiring a professional to clean the vent properly.

5. How do we maintain the filter?

Filter maintenance is a priority to keep the range hood functioning since the filter removes particulates and smoke from the air before pushing it outside the house or recirculating it. There are two kinds of filters: metal and charcoal. Metal filters can be removed easily and should be cleaned about every 3 months.

Just slide or pop out the metal filter. Then, place it in a container filled with enough degreasing solution to cover it completely. Scrub it with warm, soapy water or baking soda, and dry it completely before reinstalling. Keep in mind that some filters are dishwasher safe. Charcoal filters, on the other hand, can’t be cleaned. They should be replaced annually.

6. How can we minimize grease buildup?

The best way to keep grease under control is to prevent it from splattering while cooking. This helps reduce airborne particles and cooking smells. Use a splatter screen that contains a carbon lining to absorb bothersome odors. Most screens can be washed in the dishwasher or hand washed with a sponge and hot soapy water. Always check the manufacturer’s directions before using cleaning products on a screen.

7. How can we adjust the ducts for better airflow?

If the ductwork connected to the range hood is not working properly, there could be problems with airflow. To ensure that the suction power is adequate, try the following:

  • Check for leaks in the ducts.
  • Make sure there are no obstructions in the ducts like debris or nests.
  • Upgrade to a larger ductwork size to boost airflow.

8. How do we choose the best cookware to reduce smoke and steam?

Cookware can affect the amount of smoke, steam, and splatters in the stove area that the range hood then needs to address. Some tips to reduce these include:

  • Avoid dented, warped, damaged, or uneven cookware that can trap grease and smoke.
  • Use lids to prevent steam from escaping.
  • Choose a lower heat setting
  • Do not overcrowd the cooktop.

9. What do we do if the fan is too noisy?

If the fan noise is driving everyone crazy, there may be a problem that needs to be addressed. The screws are usually the culprit of the racket. Tighten any loose screws or bolts that secure the fan motor to the mounting bracket and the ones that fasten the range hood to the back wall and upper cabinet.

10. How do we keep the lights working?

Range hood lights can easily go out since they are so close to high heat. If the lights stop working, there are a few solutions to keep in mind. First, try changing the light bulbs. If that doesn’t help, then check the wiring and connections for any loose parts or short-circuit issues.

Another option is to take a look at the electricity supply through a multimeter to confirm that the reading matches the voltage requirements. If the lights still don’t turn on, it may be time to replace the entire range hood.

11. What do we do if smoke and odor linger in the kitchen?

If the range hood is running but the kitchen is still a bit smoky and smelly, there may be a problem to address. Check for an obstruction in the ductwork, damaged fan blade or blower wheel, faulty fan motor switch, defective blower motor, or dirty filter. Once you are able to pinpoint the culprit, it can often be fixed. If you are unsure about how to fix it or unable to figure out the problem, consult with a professional.

12. How do we prolong the life of the range hood?

Given the investment needed for a new range hood, it is beneficial to know some tips and tricks for prolonging the product’s lifespan. Follow these suggestions to extend the life of a range hood:

  • Run the hood at lower speeds to preserve the motor.
  • Regularly check the vent to keep air flow unrestricted.
  • Clean or replace the filter regularly.
  • Clean fan blades occasionally to prevent buildup of grease and grime.
  • Wash the exposed metal often with warm, soapy water.

Common range hood issues

A well-functioning range hood is an essential component of any modern kitchen, effectively whisking away cooking odors, smoke and grease. However, when you find the range hood not working, it can lead to frustration and concern. Understanding the common failures that occur with vent hoods, such as no power at all, fans refusing to spin or struggling to pull air, or lights that simply refuse to illuminate, fear not. You may be able to fix the range hood yourself as we delve into the potential problems and solutions.

Why Won’t My Range Hood Won’t Power Up?

If you find the range hood is completely dead, start with the obvious by ensuring the power cord is plugged into the electrical outlet. If it’s plugged in but not working, try checking the outlet by unplugging the range hood and testing the outlet with a hair dryer or night light. If the outlet is dead, check and reset the house circuit breaker, then recheck the outlet. If it’s still not working, you’ll need to contact an electrician for assistance.

If the outlet is working, you’ll likely need to have a Sears Technician diagnose and repair the range hood.

Why Doesn’t My Range Hood’s Fan Work?

Fan Doesn’t Turn On

When the blower fan doesn’t even turn on but the lights work, a failed electronic control board, faulty user interface, bad fan switch, wiring failure or failed fan motor can keep a range hood fan from running.

If you’re confident that you can troubleshoot the problem yourself, follow these steps:

  1. Unplug the range hood and check the wire harness connections between the control and the fan motor. Reconnect any loose wires and repair any damaged wires. With the range hood still unplugged, check the electronic control board for burn marks that indicate a control board failure and replace the control board if you find burn marks on the circuit board.
  2. If your range hood uses a user interface control to start the fan, you may need to replace the user interface if it isn’t sending signals to the electronic control board when you press the fan button. A user interface control is a keypad and display panel that sends signals to the electronic control board through a ribbon wire cable when you press its selection buttons. DIY testing of the user interface control isn’t available for most range hoods. If the electronic control board doesn’t activate the fan when you press the fan button on the user interface control, you’ll likely need to replace the electronic control board. If the fan still doesn’t work after replacing the electronic control board, you’ll likely need to replace the user interface control.
  3. If your range hood uses a switch to activate the fan motor, test the fan switch for continuity using a multimeter (with the range hood still unplugged) to see if the switch allows current to flow to the fan when you turn the switch on. Replace the fan switch if you measure no continuity through the switch with the switch turned on. If the switch or the electronic control board sends current to the fan motor but the fan motor doesn’t run, you’ll likely need to replace the fan motor (if the wires between the switch and the fan are good).

Here’s a video that shows how to check continuity using a multimeter:

Fan Doesn’t Pull Much Air

When your range hood fan runs but it isn’t pulling much air, clogged air filters, air duct problems, a fan motor failure or a broken fan blade could be causing poor air suction.

Follow these DIY troubleshooting steps to resolve an air suction problem with your range hood:

  1. If your range hood exhausts some air to the outside of your home, check the condition of the grease filters. Wash or replace the grease filters if dirty.
  2. Check the air damper on the vent duct cap attached to the outside of your house. That air damper keeps outside air from flowing into your home when the range hood fan isn’t running. Repair or replace the air damper if it doesn’t open to allow range hood exhaust air to flow out of the exhaust duct.
  3. Examine the damper above the fan in the range hood to make sure that damper opens properly to allow air to flow out through the exhaust duct system. You can use the installation instructions for your range hood to access and check that damper.
  4. Check the fan blade for damage because a damaged fan blade won’t move air through the range hood properly. Replace the fan blade if damaged.
  5. A weak fan motor won’t turn the fan blade at the right speed to move air through the range hood. If the fan motor makes noise or doesn’t turn the fan blade at full speed when activated, replace the fan motor. If your range hood recirculates the air back into the kitchen (non-ducted installation) and uses a charcoal recirculation filter, a clogged filter can diminish airflow through the range hood. Replace the charcoal filter if you haven’t replaced it according to the guidelines in your owner’s manual. Next, check the condition of the grease filters and wash or replace the grease filters if dirty. Check the damper above the fan to make sure it opens properly so exhaust air can pass through the damper and recirculation filter. Repair or replace the air damper if it’s stuck closed. Check the fan blade for damage and replace the fan blade if damaged. If the fan motor makes noise or doesn’t turn the fan blade at full speed when activated, replace the fan motor.

If you get to a point where you need to have a professional diagnose and fix your range hood, schedule a Sears Technician to visit your home and repair the range hood.

Why Won’t My Range Hood’s Lights Work?

Failures such as a defective electronic control board, bad user interface control, broken light switch, bad light bulb sockets or a wiring failure can prevent the lights from working.

Follow these DIY troubleshooting steps to resolve lighting problems with your range hood:

  1. Unplug the range hood and check the wire harness connections between the light sockets and the control board or light switch. Reconnect any loose wires and repair any broken wires.
  2. If the light socket wiring is okay, check the electronic control board for burn marks. Replace the control board if you see burn marks because the burn marks indicate a control board failure.
  3. If your range hood uses a user interface control to control the lights, you may need to replace the user interface if it isn’t sending signals to the electronic control board when you press user interface buttons.
  4. DIY testing of the user interface control isn’t available for most range hood models. If the electronic control board doesn’t activate the lights, you’ll likely need to replace the electronic control board. If the lights still don’t work after replacing the control board, you’ll likely need to replace the user interface control.
  5. If your range hood uses a switch to control the lights, unplug the range hood and test the switch for continuity using a multimeter to see if the switch allows current to flow to the lights when you turn the switch on. Replace the switch if you don’t measure continuity through the switch when it’s turned on.
  6. With new light bulbs installed and the range hood unplugged, check for continuity through the light sockets with new light bulbs installed. Replace the sockets if you don’t measure continuity through the sockets with new bulbs installed.

Troubleshooting Your Range Hood Issues

These DIY troubleshooting steps will help you resolve problems in most types of range hoods installed over the range or cooktop. But if these steps don’t help you fix the problem, schedule an appointment with a Sears range hood expert to repair it.

What is the life expectancy of a range hood?

Depending on the model and how frequently you use it, the average lifespan of a range hood is 15 years. With proper care, some range hoods can last up to 20 years.

How can I improve my kitchen hood?

Keeping the range hood and filters is the single-most important factor in improving range hood performance. A clogged filter prevents airflow through the vent system and places undue strain on the fan motor. Grease splatters left on surfaces of the range hood could, over time, cause damage to the finish.
