If you assume, you make an ass of u and me, is my personal maxim. I was told it's a 12v fridge by the seller, and separately by an engineer at the marina.

I'm looking at a blue box! 😄 It says 'charger' on it, tbh it's quite difficult to see, it's in a dark difficult to reach corner and there are lots of wires and such in the way. I am intrigued what the relationship is between running the engine and the battery - obviously running the engine charges the battery, but doesn't being plugged into the mains do the same thing? I've checked the physical mainline connection, and the 'Shoreline' and 'AC Available' lights are both on, so I'm pretty certain that isn't the problem, but does running the engine do something additional that the mains power doesn't do?

The battery says 'normal' and '14.4v' (it looks like anyway, kinda hard to see, but it's the highest), and I think it's quite new. The reason I ask about the compressor is because the fridge is very awkwardly situated (I know right, on a canal boat, who would have thought), and I don't want to keep pulling it out and pushing it back without a good reason, particularly when it's kinda, sorta, working again. I might try turning the engine on for 10 minutes just to see if it makes any difference to anything.

As far as I know, yes, although now you've got me worried. (in case you hadn't figured, I'm greener than Kermit).

Ah, ok, thanks. We're actually plugged into the mains at a marina at the moment, does that make a difference, would running the engine help? Is the compressor going to be at the bottom around the back of the fridge? Will it be obvious? I'm sorry for the noddy questions, but this really isn't my area, 'Learning about domestic electrics' is on my ever expanding to-do list that I never get around to. Right now I'm sat near the fridge, and it seems to be permanently 'humming' again, rather than doing nothing or 'stop starting' without me having done anything (of course, I have now just jinxed it so I'm sure it will go off again as soon as I post this).

We have a 12v fridge, over the last 6 months or so it's gone off on a couple of occasions, both times the problem was found to be a loose connector/plug shook unplugged type things. This morning I got up early, went to make tea and found that the fridge was off - the light comes on, but it wasn't cold in there, and everything in the freezer compartment is soggy. So I hope it's just another loose connector, I put on my man hat and go and start fiddling with wires, plugs, connectors etc. I check back on the fridge, and........nothing. Still not on. I pull the fridge out, fiddle with those wires too, and still, nothing. I leave it for a little while, and go and do something else. While doing said thing, I hear the hum of the fridge - it has come back on. Since then, this pattern has been repeating - I hear the fridge hum for a few seconds, and then nothing again. I'm ashamed to say that I have no idea whether this is normal. I never paid attention to it before when it was 'working', so now that I'm listening out for it, I have no recollection whether it used to come 'off and on' like this, or whether it was on all the time (ie making a constant noise). My feeling is that it always produced a quiet hum, but now when it's 'off', it makes no sound at all. Does anybody have any clue what this is/how worried I should be/what I can or should do about it? Thanks.
