What Calibration button light blinks continuously
actually means.
BEST hoods with the IQ Blower System run a calibration after installation. A steady light at the end means it passed; a light that blinks without stopping means the duct run is too restrictive, and the blower sets itself to maximum intensity to make up what it can. BEST lists a stuck damper flap, too many elbows, undersized or crushed duct and flex duct as the usual causes.

What to do when Calibration button light blinks continuously shows on the range hoodKind of codeDamper and downdraft
Something along the path of the air has stopped moving as it should: a motorized backdraft damper that no longer opens when the fan starts, one that sticks open and lets cold air or rain in, or on a downdraft the lift motor and its limit switches that raise the vent behind the burners. A damper taped shut since installation or a pan handle dropped into a downdraft slot can bring on the same code, so the easy checks come first.

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 BEST's own guidance for Calibration button light blinks continuously on its range hoods. Follow it to the end: the last card says whether this is a visit.
Check the outside wall cap or roof cap for a flap that is stuck, painted over or blocked by a nest.
If you want to keep things as they are, press the calibration button once to accept the airflow; the blinking stops.
Book a visit if the duct needs changes, then have the calibration cleared with a 10-second press and run again.

What not to do
The blinking does not mean the blower motor is weak or failing. It also has nothing to do with the filter reminders, which appear on the speed or fan lights instead of the calibration button.

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.
