The fan sounds the same, the lights work, and the only evidence is a film that starts appearing on the cabinet doors next to the range and a kitchen that smells of last night. Monogram’s line covers wall-mounted pyramid chimneys in 30, 36 and 48 inches with air quality sensors, island hoods, 36 and 48-inch professional hoods, and custom inserts including the brass and titanium Designer pieces — a range of shapes over one basic job. ### Three places airflow goes missing **The filters.** Baffle filters lose throughput long before they look dirty, and over a grill or a griddle they load fast. **The duct.** Every elbow costs airflow, and the roof or wall cap at the end of it has a damper that can stick shut, seize with corrosion in salt air, or become a bird’s nest. **The make-up air.** A powerful hood in a tightly sealed, air-conditioned house is trying to remove air that nothing is replacing. That is not a problem in the appliance, but it is why the appliance is not working, and it is common in newer construction here. ### Air quality sensors, and the problem that is not one The current chimney hoods sense the air and run themselves. It is a genuinely useful feature and it generates a specific false alarm: an owner who has left the hood in automatic reports that the fan does not come on, when the hood has decided it does not need to. Before anything else, run it manually at the top speed and see what happens. ### Before you book Model number, whether the lights work, whether the fan runs at all, and when the filters were last cleaned. If you know where the duct goes and roughly how long the run is, that is worth telling us too — on this appliance the installation is very often the diagnosis.

Airflow is lost in three places and only one of them is the hood. First the filters: baffle and mesh filters lose a startling amount of their throughput before they look bad, and they are dishwasher-safe on most of these. Second the duct: a run that is long, full of elbows, or terminating at a roof cap whose damper has stuck shut will strangle a perfectly healthy blower. Third the make-up air — a tight modern house with the doors shut and the air conditioning on cannot supply what a 1200 CFM professional hood wants to remove, and the hood simply cannot pull against it. ### The lights work and the fan is dead. Then power is reaching the hood and the problem is downstream of the control: the blower motor, its capacitor or the speed control. On models with an air quality sensor there is one more possibility worth knowing — the automatic mode can be holding the fan off because the sensor believes the air is clean, which reads exactly like a dead fan. Try it on manual at full speed before you book. ### How often should the filters really be cleaned in this climate? More often than the manual assumes, and much more often over a professional range with a grill or a griddle. Grease plus humidity is a worse combination than grease alone: it stays tacky, it collects dust, and it migrates past a saturated filter into the blower housing and the duct, where cleaning it is a job rather than a chore. Every few weeks through the dishwasher for a heavily used hood is not excessive here. --- **[Read full article: Range hoods](https://monogrammiami.support/appliances/range-hood/)**
