F9- outdoor EE error
Explanation of
error
Cause:
Many parameters need to be preset for the running of the external 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 main
external control panel can only work after reading the data stored in EE and if
not read, the alarm "outdoor EE error"
is
reported and
sent to
the internal
machine. 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:
main external control panel.
Tools required
for inspection
None.
Frequent
problematic part
Bad contact of EE, main external control panel.
Inspection
procedure and
key points
1. Replace the main external control panel directly.
