Angry Fridge relay

Hi
I own a 59 plate ducato Suntor 590RS the fridge works well on gas and 240v but if you switch to 12v engine running code 10 (engine not running) comes up and the blue light flashes.I have checked the fridge fuse so I think the relay is the problem ,but it does not tell you the location of the relay in the handbook and no one seems to know the hiding place not even Swift
Has anyone had this problem or do you know the hiding place ?
Cheers

Are you getting this warning when the engine is running? 12 volts is only supplied to fridge cooling when the alternator is producing.

Regarding the relay, post a photo of your engine compartment and hopefully someone will guide you to the relay.

I'm daft and proud of it.

Not familiar with Swift electrics, but on vans equipped with Schaudt controllers the function to supply fridge is via that unit.

Maybe yours will be similar and nothing to do with the actual fridge but where the supply for it comes from.

If it has a Sargent supplied PSU some are linked to an EM50 control box that has a fridge relay combined, unfortunately it's on a PCB and not like a normal relay. Sargent have good customer service so it might be worth contacting them.

A bit more info about your Power Supply Unit etc may help someone give a more helpful response.

Good luck.

Have a look above the engine in a black box (in ours it is behind the scuttle and the air filter) in the box there are two fuses and two relays, one for the step which should operate when the engine goes on to retract the step and the other to supply power to the fridge.

Worth having a look there,that was my original reason for joining MHF about 12 years ago and like you I had been unable to get an answer even from the dealer, but MHF members gave me the location in less than 30 minutes.....

Good luck, it is worth checking both fuses there first before touching the relays, ours is a 2003 Swift Kontiki 615 so a much less sophisticated fridge etc. so that may not be the answer BUT.... worth looking.

That is EXACTLY one of the things to do from the manual that we Haagen when there may be a Sargent issue apparent. We have had to do it twice when odd things have suddenly happened and weird noises have started with displays that made no sense and the unit would neither switch on or off.

I had the same problem more or less and put in my own relay bypassing the regular controller, kind of a fun project.

If you have questions about touring, living, driving, etc in Italy message me.

Sounds like you may have a loose joint in the system, possibly behind the panel, or a dodgy fuse.
