Range Hoods Maintenance
 Wipe the exterior and interior of the range hood regularly. When you need to give it a thorough scrub, use a solution of hot water, dishwashing detergent, and ammonia to cut the grease; wear rubber gloves.
Clean metal mesh filters when they are dirty, and replace the filters on nonvented range hoods every six to nine months or as often as the manufacturer recommends.
- Interior cleaning
Warning! Be sure the unit is turned off before you clean it. Also avoid spraying cleaner directly onto the light bulb or light bulb socket.
Clean the interior of the range hood with a standard household degreaser/cleaner.
- Exterior cleaning
Clean the exterior of your range hood with a degreaser/cleaner or a non-abrasive cleanser.
- Fan motor care
Most range hood fan motors don't need any maintenance. Over time, the motor and bearings may become stiff because of the constant heat, humidity, and grease to which they're subjected.
Also 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 need to replace the fan motor.
- Cleaning the Grease Trap
You can clean the grease trap(s) in your range hood by soaking it in a degreasing solution until all the grease is dissolved and then washing it with warm, soapy water.
Note: If your unit contains charcoal filters, these will need to be replaced. They cannot be cleaned.
Use of the range hood
Turn on the range hood before turning on the gas range.
- Both motors must be turned on when the range is set at high heat for stir-frying.
- When decocting Chinese medicinal herbs, make the range hood operate at a lower speed for 3-5 minutes every hour to prevent the plastic lamp covers and oil cup from softening and deforming.
- After cooking, keep the range hood rotating for 3-5 minutes before turning it off.
How far from the Cook top should the Range Hood be mounted?
Specific standards exist that set the minimum distance from the hood to cook top. 650mm for an electric cook top minimum 750mm for a gas cook top minimum. However it is always important to consult the instruction manual that comes with the cooking products, as manufacturers specifications may vary.
It doesn't work at all
- No power to the range hood
Make sure there's power getting to the range hood. Check for a tripped circuit breaker or a blown fuse. Check the wall socket (unless the hood is hard wired) for power with a voltmeter or by plugging something else in.
- Range hood fan switch
If your range hood only has a fan and no light or any other features, it won't start with a broken fan switch. Replace the switch if found defective.
- Range hood fan motor
If your range hood only has a fan and no light or any other features, it won't start with a broken fan motor. Replace the motor if found defective.
