A system for controlling the heat produced by a heater provided on a glass pane 3 of a refrigerator door 1. The system is arranged to cause heat to be generated at a high level when the door 1 is opened so as to remove or prevent condensation forming on the inner surface of the inner glass pane. The system is further arranged to maintain the high level of heat for a predetermined period of time following subsequent closure of the door whereafter the level of heat is gradually reduced to a relatively low level. |
