Baumatic fridge freezer

hi my Baumatic (its about 4yrs old) fridge freezer has stopped cooling and freezeing,the motor runs all the time and you can hear gas running through the system,any ideas? cheers guys

Usual is a loss of gas,IF (big if) the leak can be found a repair might be possible but time for an engineer to check it out.

thanks for that,i'll keep an eye out for a new one :(
