20To check the operation of the electronic (module) controller (Type 537 ABC) you will require a digitalmultimeter with the functions to measure AC/DC voltage, continuity, resistance and micro-amps.It is critical that the appliance is earthed and that the active and neutrals are not reversed.Item No Check Action1 No ignition when appliance • Check 240 volts power to heater in incoming plugis turned on. connector.2 Power present but appliance • If there is power to the brown wire in the 8 waynot operating. switch connector the module may be in lockoutmode. To reset the module turn off the power supplyfor 10 seconds and then turn the power on again.3 After resetting the module • Check the internal 3.5 amp fuse in the module.and appliance is still notoperating.4 If the fuse is O.K. and still • Check other connections are in place.appliance not operating • If the last checks are correct the ignition electrodeshould spark at the same time as the gas controlsolenoid valves open. At this point the sparkelectrode will activate for up to 10 seconds maximum until the flame has been established. Terminal14 (white wire into the 8 way switch connector)will be energised as soon as the flame has beensensed.5 Confirm spark is produced • A blue spark can be seen when the heater ignitionwhen heater is turned on. process starts. Ensure spark is present betweenelectrode and burner.6 If no spark being produced • Check that spark lead is connected into module.• Check the continuity of the HT cable.• Check that there is no short circuit to earth andspark gap is correct. (Refer figure 28). A positivecheck is to use a jumper wire and connect one endof the earth and hold the other end with insulatedpliers 4mm from the spark generator on the module.If there is no spark to earth then change the module.7 Spark is being produced • Listen for cracking sound. The spark is misdirected.but not at burner. Check the spark ceramic insulator for signs ofcracks.8 Sparks, ignites on low flame • Check that the wall socket to the appliance hasthen extinguishes after 10 correct polarity. Do not use an extension cord. Checkseconds. Continues to spark polarity in the electrical supply lead to appliance.during flame presence. • Check that the sense electrode is in the flame.• Check that appliance is earthed correctly. A checkbetween the earth pin on the plug and an unpaintedpart of the appliance should see a resistance of0.1 ohms.Troubleshooting
