Status Codes - Carrier Infinity 25VNA0 Service Manual

Status Codes

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.

repeating is 2.5 seconds with LED OFF.
Codes are easily read from Wall Control.
EXAMPLE:
3 short flashes followed by 2 long flashes indicates a 32 code.
