The system includes a memory device (110) and a processor (115) coupled in communication with the memory device. The memory device is configured to store a plurality of intensity readings from a flame sensor, wherein each intensity reading is associated with a time, and a plurality of past average intensities, wherein each past average intensity is associated with a past time interval. The processor is programmed to calculate (310) a plurality of current average intensities based on the intensity readings, wherein each current average intensity corresponds to a current time interval. The processor is also programmed to compare each current average intensity to a past average intensity associated with a past time interval corresponding to the current time interval associated with the current average intensity to create (320) a plurality of decay rates, and to estimate (330) a predicted flame sensor malfunction time based on the plurality of decay rate.",
