Question

I have just purchased a Liebherr pull out larder fridge to replace the one I already had, I am having problems getting the door seal to stay in place at the top of the fridge. When I push it closed firmy, the seal touches the metal surround of the fridge but as soon as I let go the top of the fridge door pulls away from the actual fridge by about 1 cm thus allowing warm air into the fridge. It was a really expensive fridge but I chose it because I liked the pull out design-am now starting to regret it-Help!! What can I do-it's brand new but don't think it will last long if warm air continually getting into it-many thanks Jean
