OPERATING PROBLEMS
Before calling for service, check these simple things:
Why is the rangehood not working?
- has the electricity been interrupted?
- was the rangehood on?
- is the power plug disconnected and/or damaged?
Why is the rangehood working poorly?
- was the rangehood turned on at a sufficient speed to extract the fumes and vapours generated?
- is the kitchen sufficiently ventilated to allow for good air intake?
- do the grease filters need to be cleaned?
- do the carbon filters need to be replaced (in the case of a recirculating rangehood)?
- after 10 minutes of uninterrupted operation at the fourth speed, the rangehood automatically goes to the second
speed unless a timer was activated (energy savings).
Why did the rangehood suddenly turn off?
- was there a sudden interruption of the electricity?
- is the power plug disconnected and/or damaged?
- after 5 hours of uninterrupted operation, the rangehood automatically turns off (energy savings)
