Cause: Many parameters need to be preset for the running of the indoor
unit of the air conditioner and such parameters are placed in a data
storage 8-feet chip, which is called "EEPROM" or "EE" for short. The
motor on the Indoor Unit main PCB can only work after reading the
data stored in EE and if not read, the failure code "Outdoor EE Failure"
will be indicated and raised in the indoor unit. Reasons for data not
being read are as follows:
1. wrong EE chip data format;
2. EE chip is broken;
3. bad contact of EE or fault of EE reading circuit;
4. backward installation of EE chip.
Inspection path: Indoor Unit main PCB.
