Possible causes
Troubleshoot and solution
Fan wheel is broken
Damaged during
shipment
If the fan wheel is broken and your purchase is from
an authorized seller, contact Awoco to get a fan wheel
replacement. Changing a fan wheel is not difficult.
Fan wheel is stuck
or generates
strange noise
The fan wheel is
not seated
properly
Please follow the instruction to open the front cover.
Check if the fan wheels are touching something. And
open the side panel to reseat the fan wheels to the
correct positions.
The magnetic
switch isn’t function
correctly
sometimes.
The magnetic
switch is defective
or close to an
alarm sensor
Don’t place the magnetic switch close to an alarm
sensor. The alarm sensor magnet will interfere with it.
Remove the magnetic switch connection and test if
the magnetic switch is defective.
The air curtain
doesn’t turn on.
(Make sure your
power outlet is
220V or 240V
before plugging in.)
Circuit board
failure or no power
to circuit board
Toggle the front switch; hear if “Tic-Tac” sounds from
the relay on the circuit board. No sound means no
power to motor from circuit board. Please check if the
power cord has 220V or 240V to the L1 and L2
terminals.
Motor doesn’t run.
But if push the fan
wheel, motor slowly
rotates or rotates
reversely
Startup capacitor
is not connected
securely or
defective
Check if the 2 yellow/orange wires securely connect
to the capacitor under the motor.
After above
troubleshoot
processes, motor
still doesn’t turn on
Motor is defective
This chance is very low, but it might happen.
Use Ohm meter to measure the continuity between
motor’s white wire and the blue wire to check if it is
open. Open means defective.
