10.2 Failure code
AP96NACAEA adopts operation panel+infrared control type, while AD96NAHAEA adopts wired
control type. If the air conditioner occurs failure, the failure code will be displayed on the wired
controller or the operation panel as the following chart:
Failure code Reason
E0 Indoor float switch abnormal
E1 Indoor ambient temp. sensor abnormal
