4.3.2.4 Fan speed operation
Note
For safety reasons, a switch is built into the door. The switch prevents the fan from
operating if the door is not installed. With the door removed, the appliance's control
board will remain powered, enabling programming of the mobile app.
For fan speed defaults and ranges, see the table below:
