Dryer Airflow Checker. Be sure to keep the clear hose clean and dry. Moisture or debris may give a false reading. See below for operation instructions.
1. Place the clear, kink-resistant hose into the drum (away from hinges and door strike) and close the door on the clear, kink-resistant hose.
2. Press and release the power button. Wait until the power light stops flashing (~10 seconds)
3. Assure that the dryer is empty and that the link screen is clean. Start the dryer on air cycle.
4. Wait less than 90 seconds for one of the airflow indicator lights to illuminate solidly. (Lights may flash while airflow checker is taking the reading)
