Truma Fuse Location

Hi, I have an 18 month old Swift caravan with a Truma blown air system. It appears that one of the internal fuses has blown as it works ok on gas but not on electric. Truma confirmed over the telephone that one of the fuses in the heating unit has probably blown. All the rcd's in the fuse box are ok.

There is a small removable panel on the top side of the Truma unit with a colour coded fuse within it which I've tested and is ok. I believe there is another fuse which is harder to get to. Does anyone know how to access this so I can test/replace it?

Many thanks in advance,

Andy.

    although this is a swift manual....it's all taken from the Truma site...

    you need page 14....fuses...

    Hi BoleroBoy,

         Thanks for the info. The trouble is the manual isn't very clear on how to access the 230v fuse. It just shows a diagram cut-out of where the fuse is. You can't access it via the electronic housing lid as far as I can tell.

    Cheers,

    Andy.

    I had this problem on our swift, have you tried the thermal cutout switch? It springs out and has to be pushed back in to reset it

    On page 114 labelled overheating protection 230 V

    Also note for the other 230V fuse:The fuse and the power supply lines must only
    be replaced by an expert!  

    By the way, if like ours, this will be facing the outside wall and you'll have a few inches clearance as the clever designers at Swift think it is more fun that way so be prepared to work upside down and back to front, a mirror will help. Good luck

    You have to remove the side panel below the top removable panel which if I remember correctly has screws at the top and lugs at the bottom. Due to limited clearance between the side wall and the combi this was not that easy. I then used a small mirror on a telescopic rod to see the fuse so I could remove it and fit a new one. This must be a 10amp slow acting fuse. You must disconnect the mains electric before changing the fuse.

    No worry.

    Coachman designers have the same idea.

    The on/off switch for my Truma looks like a domestic lighting switch and is located in the wardrobe where you would never find it except by accident. The service people have a habit of switching it off. Quite a challenge the first time it happened, however, I assume, that you have checked the obvious things like that.

    Hi, thanks for all your replies. I'll look for the reset switch and see if that works and then, perhaps, look for the second fuse. As the caravan is a fairly new model I don't believe it has a separate switch located in a cupboard. If anything this would probably isolate the whole unit and as the gas heating works I doubt this is the case.

    I have a swift dealership replacing the alko brakes next week as they were making an awful noise when braking due to substandard shoes which have scored the drums from new. I hope to fix this myself before it goes it for the warranty work so I know what to do if it happens again. 

    At least I have a fallback option if I don't succeed. :)

    Cheers,

    Andy.

    I've taken a look at the reset switch this morning and my findings are rather concerning. It looks like the casing hasn't been fitted properly restricting the reset switch ability to pop out. Hopefully this is simply restricting the spring which ejects the switch and the circuitry is still disabled. If not, this could prove a much bigger job to fix (see attached photo). 

    I've decided not to do any more investigations or take the side panel off so that the swift dealership can see the problem for themselves and there's no suggestion it was my fault for taking the panel off.

    It never rains... undecided

    Hi all, 

         Apparently the button in the picture above is not designed to pop out as such. A small screw driver is recommended in order to reset it. Could I suggest Truma think about a more friendly location to site the switch to help us caravan'ers reset it when required?

    You live and learn I suppose.

    Hi.

    I own a 2017 Bailey Pegasus fitted with the Truma combi 6E boiler and I discovered last week that mine had stopped working on 240V when I hooked up to the site mains. I suspected that the 240V fuse had blown but the advice from my dealer was to return the van to them for repair as the fuse is difficult to access and any resultant damage due to my intervention would invalidate the warranty.

    They replaced the fuse yesterday and while waiting in the workshop reception I had an interesting conversation with one of their staff who had previously worked for Truma. He advised me that to prevent a recurrence, prior to disconnecting the caravan from the 240V supply, the Truma operating panel should ALWAYS be switched off by holding the button until 'OFF' is displayed on the operating screen. The caravan 240V mains isolator can then be switched off and the mains cable safely disconnected from the caravan. This prevents any voltage spikes from blowing the fuse. It is a potential problem which should be brought to your attention when receiving a handover from the dealer but is typically overlooked. There's no mention of it in the Truma section of my caravan handbook either.

    Hope this helps
