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 hood

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.

01

If the LED is dark, connect the hood: hold FAN for 3 seconds and complete setup in SmartHQ.

02

If the color moves with nothing cooking, look for other sources such as candles or an open bottle of wine.

03

Run the fan if the kitchen smells; otherwise no action is needed.

04

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.

Questions
about Indoor Air Quality (IAQ) LED.

Can I clear Indoor Air Quality (IAQ) LED myself?
If the LED is dark, connect the hood: hold FAN for 3 seconds and complete setup in SmartHQ. If it comes back, it needs a visit.
Why doesn't the air-quality light on my Monogram hood do anything?
It needs Wi-Fi. Until the hood is connected through SmartHQ, the sensor is not active.
My Monogram hood's air light changed while nobody was cooking. Why?
Household sources such as candles or wine can shift the reading. Monogram's advice is to run the fan if it smells and otherwise leave it.
Does the Monogram IAQ light turn the fan on by itself?
The manual describes it only as an indicator. The automatic fan behavior on Monogram hoods comes from the separate heat sensor on the professional models.

Back to your everyday

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.
