Carrier Infinity Series AC Error Codes



Status Codes

Table 6 shows the status codes flashed by the amber status light. Most system problems can be diagnosed by reading the status code as flashed by the amber status light on the control board. The codes are flashed by a series of short and long flashes of the status light. The short flashes indicate the first digit in the status code, followed by long flashes indicating the second digit of the error code. The short flash is 0.25 seconds ON and the long flash is 1.0 second ON. Time between flashes is 0.25 seconds. Time between short flash and first long flash is 1.0 second. Time between code repeating is 2.5 seconds with LED OFF. Count the number of short and long flashes to determine the appropriate flash code. Table 6 gives possible causes and actions related to each error.

EXAMPLE: 3 short flashes followed by 2 long flashes indicates a 32 code. Table 6 shows this to be low pressure switch open.
