The simplest answer is don't try and do it yourself- get a marine (LPG) Gas Safe engineer to do it. Though a rather grey area, DIY work on a gas system is to be avoided- unless you have a bubble tester fitted or a proper LPG ratedanometer to check the gas soundness, you might think you have cured the leak when in fact there is still pressure loss.
Gas fridges are notorious is presenting problems and servicing themselves is not a good idea. Isolate the fridge and/or entire gas system until a professional has taken a look at it. It is better to be safe than sorry.
We generally cannot suggest that, apart from leak detection via a bubble tester (highly recommended) that you do any work in a gas system- one of the few (if only) areas of boat maintenance that should be left to fully trained (and insured) professionals. Note that DIY gas system work may invalidate your insurance.
I am sure Rupert will comment on this question shortly as he is a BSS Examiner.

As Mark says; only attempt work on any gas system if you are a "Competent Person", this is the wording in the regulations and the HSE definition of a competent person is one who is "Gas Safe" registered.
Leak detection fluid is used to find leaks by brushing or spraying onto joints and looking for bubbles, (you can use washing up liquid mixed with a small amount of water, but do wash it off afterwards as it is mildly acidic). It is only by testing with a manometer or bubble tester that you can be sure that there are no leaks.
If you choose to isolate the fridge, make sure that the pipe is capped properly.
By the way I will be happy to examine your boat if it is in Cheshire, North Staffordshire, or on the Peak Forest Canal.
