Re: Servis fridge/freezer problem.
I don’t have the model number to hand BUT it is the latter of the 2 you mentioned with just a rotary knob numbered 0 to 5 and definately not electroic control.
I know what you mean when you say that I shouldn’t expect it to go off straight away but I normally leave it on level 4 and whenever I have turned it lower it would knock off and then back on as and when required. My fridge has been ‘On’ for the last 10 days non-stop – even on it’s lowest setting!!
