What's wrong with my fridge freezer?

[Feek]

I bought some sausages from a farm shop yesterday, they were in the fridge. Brought them home and then I put them straight in the freezer.

This evening, I opened the freezer to take something out and noticed that they'd iced up already. The package was sealed, I've opened it to take this picture. Now I've wrapped them in another bag and put them in the chest freezer outside.

I've noticed this before recently, stuff in the indoors fridge/freezer seems to be frosting up very quickly but this has been only about 24 hours. There's no visible build up of ice in the freezer itself.

The fridge/freezer is a Bosch Exxcel FrostFree (I don't know the exact model number) and it's around 13 years old.

Any idea what's likely to be causing this?

The door seal look OK, it’s not on fast freeze and although there’s a fair bit in there, it’s not overly full at the moment.

A thermometer seems a decent good first step. I don’t have one so will get one to see.

Is there much frost around the elements inside it? If so, would be worth defrosting it.

There's no visible frost in the freezer.

Is it running?....

Yes. Not continually, if that's what you meant.

Is the frost on the inside the clingfilm? If it is they were just packaged in a damp atmosphere or there is water coming out of the sausages themselves.

Yes, it's on the inside. I guess both are possible and if this were a one-off, that's what I'd put it down to but I've noticed this a lot more over the last few months, more stuff is getting frost on the inside of the packaging quite quickly.
