The position of the other switch 29 consequently has no effect on the cooling of the evaporator 16 and thus of the normal refrigerator compartment. The Siefkühlfaoh, however, is always cooled when the compressor eats switched on by means of one of the two switches 29 or 30 , so that the freezer compartment is still cooled even if its thermostat fails.
