Any ideas what should be expected?
Put bottle of water in mine and after about 5 hours driving with unit switched on, it was hotter than when it went in.
Is this a fridge or is it just a cool box that needs ice pack in it?

It is a fridge, mine will definitely have a cold drink after 5 bours Sounds like you have an issue, do you get the green light on the switch? 2010 defender utility

Yes, green light is on but only works when ignition is on.
Looks like back to dealer to sort?

Mine only works with the ignition on - but after a decent drive the drinks are cool

In the handbook it says not to leave switched on as it can drain the battery.

This implies that it should work with ignition turned off?

It's not a fridge in the true sense, it's a thermally insulated box with an attached heat sink and fan which is activated by the switch in the centre console. It's really a cool box, if the item goes in cold then it will maintain that coldness over a journey but it will not make things cold.

does having the AC on/off affect the box? ... - .- -.

Always keep a/c on.

The box managed to heat up the contents, the sides being quite hot.

Would have thought there should be some element of coldness, certainly not heat?

I think I may have an idea for LR......instead of something that cools and is of use on the odd hot day, why not have my system that can heat up your drink for the other 360 days of the year

Stick a cold brew in it. After the next 5 hours it'll be ready to drink  Is this where I put the car details and a bit about myself ?........

It uses a Peltier cooling device, so should cool the compartment down. If it is heating up, it is not out of the question that the power supply has been reversed!

I am 90% sure mine has cooled down drinks and not just kept them cool  2010 defender utility

Sounds like it's wired the wrong way. It uses a Peltier unit, much the same as heated/cooled seats do. Connect it up and it should get cold, but if the +ve and -ve are the wrong way it will heat up instead.
