Bryant fault codes

39 documented codes for Bryant furnaces, each cited to the manufacturer's own manual. Bryant is a Carrier (ICP) brand and uses the same furnace control boards and the same status-code numbering as Carrier and Payne. A Bryant 926 flashes the same code numbers as the equivalent Carrier 58-series furnace..
