(5) Trouble Shooting
Ignition/Flame
Cause Actions to take
Noise in the drum
① contact between drum and front plate (maintain a space of
1.5~2.0mm)
②Insufficient access of grease to the bearings in the drum
vibrations, noise
① Check if volt and nut are loosen
② Disassemble service pipe and discharge pipe of exhaust and
cooling bro and part and dust accumulated in the inside of case
like wing
③ Check oil in the gear head of drive motor and tension of V belt
Cause Actions to take
Location of the high
pressure sensor
① After turning the burner switch ON, confirm that sparks are flying at a
high intensity from the nozzle of the high pressure rod (maintain a space
of 3~5mm)
② After igniting, confirm that the sparks are reaching the heat sensor
(maintain a space of 5~7mm)
③ Confirm that there is no movement of the high pressure, sensor,
breakage to the insulator, grazing or disconnection of wires, etc.
Temperature display
error
There must be no damage, breakage, dislocation or presence of foreign
matter in the sensor, and no errors due to malfunction of the
temperature adjuster
Flame
① Scale accumulation on the upper cap of the nozzle
② Distortion in shape of nozzle hole due to over-aggressive cleaning
(LPG Ф0.65, LNG 1.0)
③Confirm that gas type is identical with gas type indicated on the name
plate
Flying sparks
① Occurs due to insufficient oxygen supply because exhaust damper is
set too low, etc.
②There must be no debris such as coffee grounds or other waste in the
exhaust conduit path
