    My dometic fridge does a good job of cooling but it can be a pig to light. I can gain some access if I take the bottom vent off.

    My question, if all else fails, does it work to hold a hand held spark lighter in the right place while somebody inside holds the switch in?

    When I ask the experts, because it is gas related, they back off for fear of getting into trouble.

    Because it is 'Gas related' I would take it my nearest Dometic service engineer.:BigGrin:

    I've got it booked in for two weeks hence; but it would be useful to know if a spark lighter will get me out of a fix if it turns off in hot weather.

    sounds to me like the spark probe has moved too far from the jet assembly leaving too large a gap to jump.

    or possibly the jet is partly blocked by fallen debris from the burner tube.

    I to have had problems lighting a dometic fridge, I used to use a gas lighter, the kind of lighter where the flame is at the end of a metal tube, that worked fine.

    I have also had other problems, one of which you can check yourself.....

    The HT Cable attachment at the sparking rod at the flame assembly get weak with the heat from the flame, the attachment is very similar to an open spark plug on your car, IE not plastic around it.

    The fitting starts to become intermittent or even falls off completely, if you can pull it off without any effort then gently close it up with a set of pliers and refit it.

    The other fault I have found is with the mode change switch, (if you have the manual model).
    The way to test this is to light the gas in the usual way and the have some one look at the flame and check its lit, after a wait to heat the thermocouple release the gas press button, if the flame goes out at this point then it could be the mode switch or the thermocouple.

    PS I doubt if the spark gun idea will work as you will not be able to get the spark into the gas outlet. Also I must add the there is a danger mixing gas and flames so think about it and take care.
