In order to enable a two-door refrigerator with a freezer and a fresh food compartment to operate under low ambient air temperature, by using the lamp (2) in the fresh food compartment when the door is closed, to prevent the inner temperature of the said compartment from falling below a determined level. In this case the lamp functions as an illuminator and a heater. On one of the two branches connected in parallel to each other, there is a diode (1) connected in series to the heater position switch (4) and on the other branch is only one illumination position switch (5). This circuit is connected in series to the lamp (2) and is located before the lamp (2). The lamp (2) is used for heating purpose when the refrigerator door is closed and the heater position switch (4) is on. |
