Abstract:
A method of detecting an over-temperature condition in fresh food and freezer compartments of a refrigerator after a power interruption comprising:initializing, in a first variable set, values being defined by an interrupt temperature for each of the fresh food and freezer compartments; setting a second variable set as the value of the current sensed temperature for each of the fresh food and freezer compartments; detecting the power interruption and subsequent re-initialization of power to the refrigerator; sensing a post power interrupt temperature for each of the fresh food and freezer compartments; establishing the over-temperature condition if either the fresh food or freezer compartment post interrupt temperature exceeds the values established in either the first or second variable sets by respective predetermined amounts; and providing an indication when the over-temperature condition exists.
