Phenomenon No spark on the ignition electrode and unable to ignite fuel
Power problems No power supply loose wiring blown fuse and input voltage deviating from the standard 220V
Solutions Check and fasten all wiring replace the blown fuse and install a voltage stabilizer if necessary
Ignition electrode problems improper electrode gap carbon deposition oil dirt damaged insulation corrosion and deformation
Solutions Adjust the electrode gap to 3 to 5 millimeters clean carbon and oil dirt with sandpaper and replace damaged electrodes
High voltage cable problems open circuit aging short circuit and poor contact
Solutions Check all cable connectors and replace damaged high voltage cables
Internal component damage burnout of step up transformer failure of rectifier diode and energy storage capacitor breakdown of discharge tube
Solutions Send the device for professional maintenance or replace the igniter
Ignition gun damp or water ingress especially used in outdoor and humid environments
Solutions Disassemble and dry the ignition gun and strengthen waterproof sealing protection
Phenomenon Thin dark red spark unstable intermittent spark and difficult ignition
Excessively large electrode gap or heavy carbon deposition causing electric leakage and scattered ignition energy
Solutions Adjust the electrode gap to 2 to 4 millimeters and clean surface carbon deposits thoroughly
Attenuation of energy storage capacitor capacity leading to insufficient ignition energy
Solutions Detect capacitor parameters and replace the capacitor if the capacity is lower than the rated standard
Aging cables and high contact resistance causing serious voltage drop
Solutions Replace aging high voltage cables and fasten all connecting joints
Low input voltage resulting in insufficient output energy of the igniter
Solutions Stabilize the input working voltage
Phenomenon The igniter shell heats up obviously in a short time and even becomes scalding hot
Overlong continuous working time single ignition time exceeds 30 seconds and frequent continuous startup
Solutions Control single ignition time within 30 seconds and keep an interval of more than 1 minute before restarting
Internal short circuit or electric leakage caused by component breakdown and aging insulation
Solutions Cut off the power supply completely check and eliminate all short circuit points
Poor heat dissipation caused by closed installation space and surface dust coverage
Solutions Clean surface dust regularly and reserve sufficient ventilation and heat dissipation space
Phenomenon The igniter starts ignition repeatedly without manual operation
False trigger of control loop caused by wrong wiring signal interference and relay adhesion
Solutions Inspect the control circuit eliminate external signal interference and replace faulty relays
Fuel leakage and abnormal fuel concentration causing safety interlock trigger
Solutions Troubleshoot fuel leakage points and ventilate and replace internal gathered gas
Phenomenon Blue spark and popping sound occur at the connection of high voltage cable and igniter
Poor contact caused by loose joints oxidation and surface dirt
Solutions Cut off the power supply clean the contact surface fasten the connecting nut tightly and replace the connector if severely damaged
Phenomenon The spark is normal but the fuel cannot be ignited successfully
Abnormal fuel conditions poor fuel atomization improper fuel pressure and insufficient fuel heat value
Solutions Adjust oil pressure or gas pressure to improve fuel atomization effect
Improper air distribution excessive air volume blows out the spark or insufficient air volume causes oxygen deficiency
Solutions Reduce auxiliary air volume during ignition and gradually increase air volume after successful ignition
Improper ignition position the spark is not in the effective combustible area
Solutions Adjust the insertion depth and installation angle of the ignition gun
Operation sequence Turn on the igniter first then supply fuel and stop the igniter immediately after successful ignition with single ignition time no more than 30 seconds
Intermittent working rule Work for 30 seconds and rest for 60 seconds to avoid long term continuous operation
Weekly maintenance Clean carbon deposits on ignition electrodes and check the tightness of cable joints
Monthly maintenance Detect insulation resistance working voltage and check the fastening of fixed bolts
Quarterly maintenance Calibrate electrode gap and test ignition energy stability
Environmental protection Avoid rain erosion humid environment and heavy dust install a protective box for outdoor equipment
First confirm the power supply is normal including voltage wiring and fuse status
Second observe the spark status No spark means check cables ignition gun and internal components Weak spark means check electrode gap and carbon deposition
Third clean the ignition electrode and adjust the gap to 3 to 5 millimeters
Fourth check the high voltage cable for damage and short circuit
Fifth check whether the ignition gun is damp and dry it thoroughly if necessary
Sixth send for maintenance or replace the igniter if the fault still exists after inspection
