ABSTRACT:
A system and method of determining and displaying a failure in an electronic appliance control system employs diagnostic codes which indicate both a primary system where a fault occurs and a subsystem in fault. The diagnostic codes are displayed so that repair personnel may be able to more accurately replace only the faulty part, as opposed to replacing an entire appliance control system. The diagnostic codes are established to include a plurality of digits represented by a combination of letters and numbers. The electronic appliance control also preferably records a specific series of diagnostic steps taken to verify replacement of only an actual faulty component.
