Yip Dave thanks for the info / help and yip a new electrode is ordered , but obviously with holidays it will not be here until new year , lets hope that is the problem as i have noticed that the spark / electrode part at the end is able to rotate and drop down onto the top of the burner thus reducing the 4mm gap between the electrode and the burner to like 1mm.I refer you to my previous reply:
"Thetford fridges don't use a thermocouple, they use flame rectification to detect combustion. Once the flame is lit the ionized has in the flame conduct to earth from the electrode. The reason yours is still sparking once kit is that the flame failure circuit has failed. This might be due to a dirty electrode or the burner itself may be partially obstructed causing the flame to not hit the electrode, if none of the above them it's likely to be the main pcb which is about £150 or so."

Its like the wire that runs up through the middle is no longer fixed to the center of the unit and is allowed to turn inside the unit.
