Trying to locate a 20 amp battery fuse that feeds the fridge with 12v when driving. On a fiat Ducato.. tried several places and nothing:( online they start at 30 amp. Pic attached.

Yeah. They are midi link fuses.

Any idea why it blew? Might be worth taking a peek at the fridge control board. Look for smoked and melted connectors. It's a common issue.

Yes it was the fridge control board.. I have one on the way
 
I've not had to have dealings with midi fuses. I presumed they were sealed units. Do the lids prise off?
Same I was just checking for a reason the fridge wasn't cooling when engine running.. I didn't even realise it was a fuse I was just checking the supply with a volt stick.. power one end but not the other so I prized the cap off. don't think it will go back on :)
 
Worth checking the fridge 12V element too, it should have a resistance of about 1 ohm. If it's a lot more or a lot less then the element has failed. The reading is near the lowest ohms reading that the meter can do, but you should still be able to tell a good element from a shorted one.
 
Could it be that it is alongside the fridge relay. It appears to be on a 2006 autotrail. There are usually 2 relays, one for the fridge / step and one for the split charge.
