NER NOT WORKING Burner ignition spark not working A faulty spark system is one that does not light the burner at all If the burner is being lit temporarily but fails to stay alight then the problem is in the flame sensing not spark ignition Refer Burner flame not being sensed following Firstly determine if spark is being generated Remove the front service panel and turn the thermostat on to initiate a heating cycle Look through the round viewing holes next to the electrode assembly and look for spark generation at the end of the electrodes If spark is heard but not visible turn off isolate gas supply and remove electrode assembly With gas supply off turn thermostat back on again with electrode assembly suspended in air A correctly functioning ignition system should show sparking visible across spark and earth rod ends If spark is not seen at electrode ends or sparking is erratic this indicates that there is a high voltage short breakdown between the ignition box and the electrode ends Possible causes to investigate are as follows inspect and correct as necessary Spark gap too large see the following section Cracked spark rod ceramic or carbon build up HT leads to spark electrode and earth broken deteriorated HT leads between ignition electrodes and ignition control box broken deteriorated No spark from ignition box refer ignition box faulty Spark gap setting With spa
