Before departure to our caravan holiday in Corsica some 3 weeks ago Dafydd tested the gas fridge, the gas hob, the 12v electric for the fridge, the 240v test and at the same time we had a new a 13 pin socket fitted to the car and caravan by 'the local garage mechanic, whom Dafydd holds in high esteem. Everything was working as it should. Now the fridge ignition won't work. Seeing the flame is not a problem, and when Dafydd presses the ignition button, the flame usually appears on the second application, and a gentle pop can be heard as it ignites. Now it does not ignite. This is the problem. Can anyone help please?
