A refrigerated appliance includes a power interrupt system for detecting an out-of-range temperature condition in a fresh food or freezer compartment after a power interruption. The power interrupt system includes a central processor including a memory storage module and a plurality of temperature sensors. In operation, the power interrupt system compares sensed temperature values with stored temperature variables. If, after a power interruption, a compartment temperature exceeds a stored temperature variable by a defined amount, an over-temperature flag is triggered. Preferably, a display unit flashes an indication of the highest temperature reached by each compartment intermittently with the current compartment temperatures and an indication that a power interruption has occured. In this manner, a consumer can make an informed determination whether food stored within the appliance has been exposed to temperatures high enough to cause spoilage.
