Diagnostics and Remedies
Symptom
If the dryer will not run
The dryer cycles by itself
or runs constantly
The dryer makes a loud
noise and does not run
for a complete cycle
The dryer runs but air
stream is low pressure
and/or low velocity
Symptom
If the dryer will not run
The IR sensor only "sees"
close range objects
The air stream is low
pressure and velocity

Corrective Actions for Initial Installation Failures
First ensure that the breaker supplying the dryer is operational. If it is,
disconnect the power and remove the dryer cover. Taking 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 there is no obstruction on or in front of the IR sensor. Clean
any dirt or debris off the sensor lens. If problem persists, replace sensor.
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 unit
rating label and correct supply as required. If CBM has been damaged,
replace CBM, IR sensor module.
Ensure that the supply voltage is correct. Dryer will run weakly if the
input voltage is too low. Verify voltage requirement on unit rating label
and correct supply as required.
Corrective Actions for In-Service Failures
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 IR sensor module or disconnect heater element from circuit;check
resistance (Ω) of element with multimeter. If Ω is off-scale infinitely
large then replace element. If Ω is between 25 and 30 then check
motor brushes for wear and replace them if remaining graphite is
≤ 25/64" [10 mm ]. If after reassembly and testing there is stil no motor
function then replace motor. Taking suitable precautions to avoid
shock hazard, reconnect the power and check for Voltage at the
terminal block.
Ensure that there is no obstruction on or in front of the IR sensor. Clean
any dirt or debris off the sensor lens. Check VR for sensor range setting. If
problem persists, disconnect the power and remove the dryer cover and
replace CBM, IR sensor module.
Check the output nozzle for obstructions. If none are present, disconnect
the power. Remove the dryer cover. Remove any dust/lint buildup from
intake vent slots. Check VR for speed setting. Disassemble the blower-
motor/fan housing. Check the motor brushes for worn condition (≤ 25/64"
[10 mm] graphite remains) and replace them, if necessary.
