• Outdoor PCB
Troubleshooting and repair:
Shut off the power supply and
turn it on 2 minutes later.
Is it still displaying
the error code?
YES
Replace the indoor main
PCB(E0/EA/EH 00/EH 0A)

Note: For certain models, outdoor PCB could not be removed separately. In this case, the outdoor electric
control box should be replaced as a whole. This pictures are only for reference, actual appearance may vary.
Troubleshooting and repair of compressor driven chip EEPROM parameter error and communication error
between outdoor main chip and compressor driven chip are same as EC 51.
