Then hold a sheet of kitchen paper against the filters with the fan on full — it should hold there. If it falls, the hood is not moving air and the filters are the first place to look. ### What it usually means, by the kind of Monogram appliance Monogram sells one appliance in several forms, and the same behavior points at different things on each of them. A built-in side-by-side and an integrated column are not the same service situation, and a dual-fuel range and an induction range fail in different halves. - **Chimney hoods with air quality sensors** — Automatic mode can hold the fan off because the sensor believes the air is clean. Run it manually at full speed before assuming anything. - **Professional hoods over a 48-inch range** — Serious airflow, and therefore serious dependence on the duct and on make-up air. These are the installations where a tight house shows up first. - **Island hoods** — No wall to help them and a duct run that goes up through a ceiling, so more of the resistance is out of sight. - **Custom inserts** — The blower and the lighting are ordinary; the chimney around them belongs to a cabinetmaker, and the access is decided by the joinery. ### The quietest failure in the kitchen Nothing tells you a hood has lost half its airflow. The fan sounds the same and the lights still work. The evidence is a film that starts appearing on the cabinet doors beside the range and a kitchen that smells of last night — and by then it has usually been going on for a year. Loaded filters Baffle and mesh filters lose a startling share of their throughput before they look bad. Most are dishwasher-safe. Grease in the blower housing What gets past a saturated filter, and it is a job rather than a chore once it is there. The duct run Elbows, crushed sections and length. Each costs airflow permanently. The termination outside A damper stuck shut, corroded in salt air, or taken over by birds. Invisible from inside. A powerful hood in a sealed air-conditioned house cannot remove air nothing is replacing. The blower or its capacitor When the fan is genuinely not running rather than not pulling. Run it manually at full speed Automatic mode is the first thing to eliminate. Do the paper test A sheet held against the filters should stay there. Take the filters out and look Then run them through the dishwasher. Crack a window and try again If it suddenly pulls, the house is the problem and not the hood. The fan runs and the kitchen still smells What it usually means Filters lose airflow long before they look dirty The termination outside is invisible from inside A sealed house cannot supply the air Run it manually at full speed first On the current hoods, automatic mode decides for itself and a hood that will not come on may simply have concluded the air is clean.

More often than the manual assumes, and much more often over a grill or a griddle. Grease plus humidity stays tacky and collects dust. Every few weeks through the dishwasher for a heavily used hood is not excessive. ### What is make-up air? The air that has to come into the house to replace what the hood sends out. In a tight, air-conditioned house there is nowhere for it to come from, so the hood is pulling against a vacuum. Cracking a window while it runs is a free test. --- **[Read full article: Range hood not pulling air](https://monogrammiami.support/symptoms/range-hood-not-extracting/)**
