Possible reasons
Refer to the outdoor unit trouble
shooting
list
1. For the indoor failure,only running LED ON remote receiver will indicate.
2. For the outdoor failure,timer LED and running LED will indicate.timer LED of remote receiver stands for ten's place,and running LED stands for one's
place.timer LED will flash firstly,2 seconds later,running LED will flash too. Afer that,4 seconds later,they will flash in turns again.Flash times equals to the
failure code of outdoor plus.
20.For example,failure code of outdoor is 2,the indoor unit should display 22.As a result,timer LED flashes twice firstly,then running LED flashes twice.
3.To get much more details of outdoor unit failure,Please refer to the the outdoor unit trouble shooting list.
