Solution
No airflow even when hands are
inserted.
Do the display indicators light
up?
Is the power switch on?
Are you putting your hands all
the way into the dryer to activate
the sensors?
Check the main circuit breaker and also the fused spur to
make sure there is power to the hand dryer.
Make sure you cover both sensors with your hands when
using the hand dryer.
The dryer continues to operate
even after hands are removed
and eventually shows E2.
Is there any dirt or obstruction in
front of the sensors?
Turn off the power switch and then clean the inside of the
hand dryer paying particular attention to the sensors located
near the LED lights. When finished turn power back on.
The airflow is cold.
There is a built in heater in the
hand dryer, Check to see if the
heat switch is turned on.
Check to see if the fuse in the
terminal block or inline fuse to
the element is blown.
Check to see if there is any dirt
or obstruction on the heater
element.
Check to make sure there is
continuity through the element.
Turn off the power switch and check the heat switch, if it is
off then turn it on.
Check the fuse; if it is blown replace it with one of the same
size and type. Check the element for continuity, dirt, or
obstructions.
The airflow is not fast enough.
Check the air speed switch.
If the switch is on low then change it to high.
If the above solutions do not solve the problem, turn off the power to the hand dryer and call your installer or the ATC Technical
Department for advice.
