Range Hood Common Questions

These common questions about range hoods are the ones our experts hear the most often from our customers.

When you’re ready to make a repair, searspartsdirect.com has the part you need, no matter where you bought your range hood.

Why doesn’t my range hood work?

If the range hood doesn’t work at all, check whether the house circuit breaker has tripped; if so, reset it. A break in the power supply wiring also would prevent the range hood from powering up. 

If the range hood has power, the problem could be with the electronic control board or the selection switches. 


Why don’t the range hood lights work?

If the range hood lights don’t come on but the fan works, check whether the light bulbs are burned out. If the light bulbs aren’t burned out, the vent hood may need a new electronic control board or light switch. A wiring failure can also cause this problem. Check the wiring connections.


Why doesn’t the range hood fan work?

If the range hood fan doesn’t work but the lights come on, remove the filters and check the fan blade to see if it's jammed or blocked. If you can manually rotate the fan blade, the fan blade could be defective. 

If the fan motor isn’t being activated, the problem could be with the control board or fan switch. 

A failure in the wire harness could also prevent the fan from running.

Can my range hood be vented into the attic?

Range hoods can’t be vented to the attic. Range hoods should be vented to the outside of your home through a proper exhaust vent duct system. Most models can be configured to recirculate the exhaust air through a charcoal filter and back into the kitchen space. Venting the range hood to the attic or similar space inside the home isn’t recommended because the exhaust air is laden with flammable grease and odors.


How do I clean the range hood grease filter?

Clean the range hood’s grease filter by washing it in warm water and a mild detergent. You can also wash most grease filters in your dishwasher. Rinse the grease filter well and let it dry completely before reinstalling. Refer to your owner’s manual for more guidelines.


Can the range hood charcoal filter be washed?

The range hood’s charcoal filter can’t be washed. Replace it every 6 months to 1 year. Replace the charcoal filter immediately if it becomes clogged with grease or residue.


Why is the range hood fan noisy?

Range hood fan noise can be caused by loose installation mounting screws in the range hood. Tighten any loose screws in the brackets and body of the range hood that fasten the range hood to the back wall and upper cabinet. Also tighten loose screws or bolts that secure the fan motor to the fan mounting bracket. An unbalanced or loose fan blade can cause vibration noise. Check the fan blade for damage or looseness. Tighten or replace the fan blade if necessary. 


What type of cleaner can I use on the range hood?

Range hoods should be washed regularly with a clean cloth, warm water and mild detergent. Rinse well with clean water and dry immediately.  Use manufacturer-recommended stainless-steel polish on stainless-steel range hoods. Refer to your owner’s manual for specific guidelines on cleaning the range hood.


What are sones?

A sone is a standard unit of loudness. The sone rating is used to compare the noise output of range hoods when the exhaust fan is running. One sone is approximately the equivalent of a small desk fan. Normal conversation is about 4 sones. 


Can the downdraft vent system be installed behind a range?

The downdraft system is designed to be installed behind drop-in cooktops. The downdraft vent system isn't designed to be installed behind slide-in or drop–in ranges. 


What is the airflow rating (CFM) of my downdraft vent system?

The downdraft vent system with a self-contained blower is typically rated at 500 CFM. Downdraft models using an external blower can vary between 600- 1500 CFM depending on your choice of external blower.


Why does the downdraft blower motor vibrate?

Check and tighten the 3 blower motor mounting nuts and rubber isolators for damage. Check for loose panel mounting screws and tighten. If the 3 motor mounting nuts are tight then the blower wheel is likely out of balance, replace the blower wheel. See our How to Replace the Blower Motor repair guide section for assistance in accessing the components in the downdraft vent system.


Why does the pop-up vent go up and down continuously?

The up/down activation switch and bracket assembly is adjusted too high, causing the switch to be continuously depressed. Remove the fan control cover from the right side of the vent. Use the 2 adjustment screws located behind the fan control cover to loosen and lower the fan control switch and bracket assembly. Loosen the 2 adjustment screws from the fan control bracket and then slide the bracket down and retighten the screws.


A defective or misadjusted limit switch can also cause the vent to continuously go up and down. Check for a damaged limit switch assembly.


Why won't the downdraft pop-up vent raise?

Check to see if the power cord is plugged into the receptacle. Unplug the downdraft power cord from the receptacle. Plug a small lamp or other small electrical device into the receptacle and confirm the receptacle has power. If the receptacle has power, check that the up/down button pad is contacting and pressing on the up/down activation switch when pushed. If it’s not, the switch needs adjusting. The installation instructions will have instructions for accessing and adjusting the up/down activation switch. If the up/down button pad is contacting and pushing the up/down activation switch, check the up/down switch and wire connections. Check the two limit switches and adjust them if needed. The cam should activate only one switch when the vent is in the down position.


Why won't the downdraft blower motor come on?

Check the fan control switch located on the right side of the vent. Make sure the fan control is switched to the ON position. Turn the fan control switch clockwise to turn the fan ON. If the blower will not come on when raised, one of the limit switches is not likely closing and completing the wire circuit to the blower motor. 


Can the downdraft blower discharge be repositioned?

Yes, you have an option to change the vent discharge from the bottom to the left or right side if your floor joist, plumbing or wiring interferes with the installation of the venting. See the installation instructions for changing the discharge position.


What is the maximum length of ductwork for my downdraft vent?

The vent system will operate most efficiently when ductwork does not exceed 40 feet of equivalent duct. Keep in mind that transitions and elbows restrict airflow and must be included when adding up the length of ductwork. The installation instructions will have an image of the transition and elbow and how many feet of ductwork its equals. For example, a 6-inch round elbow equals 6 feet of a straight run of a 6-inch vent pipe. 


How long is the power cord on my downdraft vent?

The power cord on the downdraft vent system is 2 feet long with a 3-prong plug. When planning the installation, keep in mind that the wall outlet can't be located on the back wall of the cabinet. 


How often should I clean the filters on my downdraft vent?

Soak and then agitate the aluminum mesh grease filters in a mild detergent and hot water or place the filters in the dishwasher once a month, depending on the amount of usage. Use a nonphosphate detergent or discoloration of the filter may occur. Discoloration will not affect the grease filters. Never operate the downdraft without the grease filters in place.
