What Indoor Air Quality (IAQ) LED
actually means.
Monogram's pyramid hoods with Air Quality Sensors carry an LED that changes color as the air near the hood changes. The sensor stays inactive until the hood is commissioned to Wi-Fi through the SmartHQ app. Monogram presents the reading as a general sign of change, not a measurement.

What to do when Indoor Air Quality (IAQ) LED shows on the range hoodKind of codeHeat and grease sensors
A sensor inside the canopy has stopped telling the control a believable story: the heat sensor that starts the fan when the air above the burners gets hot, or on some hoods a sensor that reads grease or steam to set the speed. One that reads hot all the time keeps the blower running with the burners long cold; one that reads nothing leaves the automatic mode doing nothing. The sensor, its wiring and the canopy around it are checked at the visit.

Testing the sensor that starts the fan by itself when the burners get hot, so the hood starts when it should and stops when the heat is gone.
Shows up asReading a Range Hood Error Code or Blinking Light
A range hood error code may appear as letters and numbers on a display, a light that blinks in a pattern, a filter reminder that will not clear, or a beep with the fan refusing to start.

Before you book,
in this order.
Each step comes from Monogram's own guidance for Indoor Air Quality (IAQ) LED on its range hoods. Follow it to the end: the last card says whether this is a visit.
If the LED is dark, connect the hood: hold FAN for 3 seconds and complete setup in SmartHQ.
If the color moves with nothing cooking, look for other sources such as candles or an open bottle of wine.
Run the fan if the kitchen smells; otherwise no action is needed.
If the hood is online and the LED never changes, book a visit.

What not to do
A color change is not an error code and says nothing about the blower or filters. A dark LED on a hood that was never connected is expected.

Heat and grease sensors on other makes
Wall-mount range hood
The chimney hood fixed to a bare stretch of wall above the burners, its canopy catching the rising smoke while a telescoping cover hides the duct that climbs to the ceiling.
Under-cabinet range hood
The slim hood screwed to the bottom of the wall cabinet over the burners, venting up through that cabinet or back through the wall, or cleaning the air and returning it to the room.
Island range hood
The hood that hangs from the ceiling over burners set into a kitchen island, open on all four sides, with its duct and wiring hidden inside a chimney that drops from above.
In Monogram's own words

Still showing Indoor Air Quality (IAQ) LED?
Three things make the booking useful: the letters or blink pattern exactly as they showed, the full model number from the label behind the filters, and whether the fan still moves air on every speed. With those, the technician arrives with half the answer already worked out.
