Downdraft vents Cooktops and ranges
Jenn-Air brought downdraft venting to home cooktops: a fan under the cooktop pulls smoke and steam down instead of up into a hood. Grease builds up on the filter and the blower over time, and the fan gets louder while pulling less. On pop-up models, the vent that rises behind the cooktop has its own motor and switch.
Colby cleans or replaces what’s clogged and tests the blower motor and the vent’s lift.
