Question

Dometic rm7401 works on 12v and 240volt bit on gas it clicks then you hear a woosh noise then it starts to click again and does not work Help!

Answer

It would appear that the gas burner needs cleaning. There is a gas build up before ignition and this has the effect of blowing out the flame. (whoosh) The spark being generated is not capable of lighting the gas and this is normally caused by debris on the burner. (May be a fly or a spider). The fridge will need to be removed from its location to access the burner.
