Range Vent Hood Maintenance Tips

Return to Appliance Maintenance Tips


Clean the metal mesh filters often. The thin, silvery screen is the grease filter (there may be more than one). The filter traps airborne oils and grease to keep them out of the blower and exhaust vent. To clean the filter, remove it and soak it in a degreasing solution until the grease is dissolved. Next, wash it with warm, soapy water to remove any traces of the degreaser. Then put it in the upper rack of the dishwasher and run it through a normal cycle. Most charcoal filters cannot be cleaned and replacement may be necessary.

Light Bulb

Use the manufacturers suggested replacement light bulb to avoid damaging the light lens cover and/or other components in the microwave.

Blower wheel

Over time, the blower wheel gets greasy and dirty, which can slow down the fan or cause vibration. Remove the wheel and clean it with a degreaser. Then, if the fan is still slow or if it vibrates, you will need to replace the fan motor.


Clean the interior of the vent hood with a standard household degreaser/cleaner. Be sure the unit is turned off before you clean it. Also avoid spraying cleaner directly onto the light bulb or light bulb socket.
