Hi ALL I need advice again with my Fanmaster 2000 space heater electronic gas ignition system. I have traced the fault to what seems to be a micro switch that is placed in what I think is some kind of igniter box if I depress the igniter / control knob nothing happens however if I press down as usual an press the micro switch on the box then it lights ok and I can use the control as normal, however the green LED does not light up, When I realise the micro switch the LED flickers for a split second can I strip the box to get at the microswitch or buy a new box any advice will be greatly appreciated
