How Do I Use the Turbo Vent?
The vent fan removes steam and other vapors from surface cooking and protects the microwave from too much heat rising from the cooktop below it. It automatically turns on if it senses too much heat. Press the Vent Fan Turbo/Hi/Low/Off button once for turbo fan speed, twice for high fan speed and three times for low fan speed or four times to turn the fan off. If you have turned the fan on, you may find that you cannot turn it off. The fan will automatically turn off when the internal parts are cool. It may stay on for 30 minutes or more after the cooktop and microwave controls are turned off. The Vent Fan will operate only in Hi/Low/Off mode while the microwave is working.
