Hi… I am having problems diagnosing a fault on this whirlpool built in fridge freezer.. It is not installed correctly due to no ventilation in plynth but it has been there for 6 years. The fault is that the fridge is a bit warm… roughly plus 8 – plus10 degrees on average.. the freezer is ok and the evaporator is clear… i am suspecting that it is the flap thermostat by sald drawers… please can someone clarify or any other suggestions… many thanks. ❓
