Sounds to me the thermopile (thermocouple) is at fault, it's a safety device to detect if the pilot flame is alight or not. If the pilot should go out for any reason, the thermopile will detect this & shutdown the gas valve (ie the unit will cease to operate). A new thermopile should solve your problem. It's not a task I would attempt yourself if you are in any doubt.
I see....does the pilot flame look ok, ie. is the jet completely clear?
it only needs the smallest obstruction to cause a weak flame that can be extinguished when the main burner kicks in.I see....does the pilot flame look ok, ie. is the jet completely clear? it only needs the smallest obstruction to cause a weak flame that can be extinguished when the main burner kicks in.
