RCD tripping same time every night

[UNG]

Thanks so much, I'll get someone in to have a look at it!

Have you checked if there are any manufacturer recalls on the fridge / freezer wouldn't be the first time that an appliance batch had a faulty part fitted, an RCD tripping problem I was called to a few years ago was down to a fridge / freezer just out of warranty I found it was caused by a faulty auto defrost element after a few enquires I found that the part had been superseded as the original element was part of a faulty batch of auto defrost elements after contacting the manufacturer they repaired it
