Abstract
This work presents a study and development of an innovative fault detection system for temperature sensors of household refrigerators. The proposed algorithm is based on the temperature difference between defrost and fresh food sensors and comparison with normal operating conditions. An experimental apparatus was designed to validate the fault detection method and a fault generation scheme was introduced to modify the temperature signal in accordance with different types of faults found in real world. A set of experimental tests in several ambient temperature conditions were performed suggesting efficiency and reliability of the fault detection algorithm.
