Diagnostics and Remedies
If the dryer will not run
The dryer cycles by itself
or runs constantly
The dryer runs but air
stream is of low pressure
and/or low velocity
Ensure that there is no obstruction on or in front of the IR sensor. Clean
any dirt or debris off the sensor lens. If the problem persists, contact the
distributor for assistance.
First ensure that the breaker supplying the dryer is operational. If it is,
disconnect the power and remove the dryer cover. Take suitable
precautions to avoid shock hazard. Reconnect the power and check for
voltage at the terminal block. Verify that connections are made correctly.
Ensure that the supply voltage is correct. Dryer will run weakly if the
input voltage is too low. Verify voltage requirement on the unit rating label
and the correct power supply as required.
The dryer makes a loud
noise and does not run
for a complete cycle
Ensure that the supply voltage is correct. Dryer will make a loud
humming noise if the input voltage is too high. Verify voltage requirement
on the unit rating label and the correct power supply as required.
If the problem persists, contact the distributor for assistance.
Symptoms Corrective Actions for Initial Installation Failures
Symptoms Corrective Actions for In-Service Failures
If the dryer will not run
The IR sensor only sees
close range objects
" "
The dryer only blows cold
air during a full cycle
First ensure that the breaker supplying the dryer is operational. If it is,
disconnect the power and remove the dryer cover. Replace the CBM
and the IR sensor module. Take suitable precautions to avoid shock
hazard. Reconnect the power and check for voltage at the terminal block.
Disconnect the power. Remove the dryer cover and disassemble the
blower-motor/fan housing. Test the thermostat for open circuit. Check
the heater element for signs of burning or breakage. Damaged element
must be replaced.
The heater gets hot but
no air stream is produced
or the air stream is of low
pressure and velocity
Disconnect the power. Remove the dryer cover and disassemble the blower-
motor/fan housing. Replace the fan motor.
1.Ensure that there is no obstruction on or in front of the IR sensor. Clean
any dirt of debris off the sensor lens.
2.Remove objects under the sensor if any. Disconnect power and
reconnect it to reset the auto-detecting sensing range.
3.Check the VR for the sensing range setting.
4.If the problem persists, contact the distributor for assistance.

Check if the LED light cable is connected with the circuit board of the
dryer body under the counter.
LED light indication is not
