  If the stage 3 fans are not running on your Airstream Controller, make sure the wiring is correct and replace the fuse if the stage's fuse is open. Also, be sure the display board interconnect cable is firmly plugged in. Check if the fan motor or heater is defective by connecting it to an alternate power supply. Listen to see if there is a clicking sound when the stage or heater-mist pilot light turns on, as the controller might be defective.
