The LED will display error code EI and the zone number that lost communication. Operate the fan without cooling until the frost disappears.Į1: Loss of communication between the CCC 2 thermostat and an individual system power module board. Table 6 gives possible causes and actions related to each error.Ġ0,01,11,12,04,05 02,03,14,15,17,18,19,07,08Ĭarrier Window Room AC Error Codes Carrier Window Room AC Error Codes Count the number of short and long flashes to determine the appropriate flash code. Time between code repeating is 2.5 seconds with LED OFF. Time between short flash and first long flash is 1.0 second. The short flash is 0.25 seconds ON and the long flash is 1.0 second ON. The short flashes indicate the first digit in the status code, followed by long flashes indicating the second digit of the error code.

However, the check codes are not deleted even if the power supply is turned off because they are stored in the fixed memory.Ĭause of operation: Short-circuit or disconnection of the room temperatur sensor (TA sensor).Ĭause of operation: Being out of place, disconnection, short-circuit, or migration of heat exchanger sensor (TC sensor)Ĭause of operation: Lock of indoor fan or trouble on the indoor fan circuitĬause of operation: Trouble on other indoor P.C.

After servicing by the check code, turn off breaker of the power supply, and turn on breaker of the power supply again so that memory in the microcomputer returns the initial status.

After servicing, push the button to return to the normal mode.

The check codes can be confirmed on the remote controller for servicing.

When item B and C, and item B and a part of item E occur concurrently, priority is given to the block of item B.

The contents of items B and C and a part of item E are displayed when air conditioner operates.
