  • The outdoor unit is not turned on.
  • When the network of indoor/outdoor operation line was wired, the (SHORT) setting of the terminal resistor switch on the outdoor control PC board was set on multiple units (four or more).
  • When the power was turned on after auto address setting was completed, the number of indoor units had been changed.
  • Forgot to turn on the indoor unit.
  • The CHK pin and/or TEST pin on the indoor unit’s control PC board are shorted.
  • Forgot to install the nonvolatile memory (EEPROM) when replacing the indoor unit control PC board.
  • Mistakenly set the indoor unit address to Not Set in the remote control’s detailed setting mode.
  • When indoor unit addresses are duplicated.
  • There is a short, open, wrong contact or grounding of the indoor/outdoor operation line.
  • There is an error in the receiving circuit on the signal output PC board (optional control PC board).
  • Malfunctions of the outdoor unit High voltage was applied (over AC200V) in the indoor/outdoor operations line circuit.
  • The thermistor inside the indoor unit is grounded.

2. Error Diagnosis

1
Power Source
1-1 Is/was the power to the outdoor unit cut off? Yes After turning the power on, wait three minutes
No 1-2
1-2 Is the indoor unit powered off? Yes Power on

2-1 Is the indoor/outdoor operation line shorted, opened, grounded or has a wrong contact? Yes Correct the wiring
No 2-2
2-2 When the network of indoor/outdoor operation line was wired, was the (SHORT) setting of the terminal resistor switch on the outdoor control PC board set on multiple units (four or more)? Yes Normally the (SHORT) setting is just one unit.
No 2-3
2-3 Was a high voltage (over AC200V) applied in the indoor/outdoor operations line circuit? Yes 3-2
No 3-1
3
No. of Indoor Units
3-1 Was the number of indoor units increased or decreased after auto address setting was complete? Yes 3-2 
No 3-3
3-2 Conduct checks prior to auto address setting.
3-3 Check the indoor unit addresses from the remote control’s detailed settings mode.
Is it Not Set (99), or is the indoor unit’s address duplicated?
Yes 3-2
No 4-1
4
Indoor unit control PC board
4-1 Are the CHK pin and/or TEST pin on the indoor unit control PC board short-circuited? Yes Remove the short
No 4-2
4-2 Is the wireless remote controller and/or optional control PC board connected to on the indoor unit’s control PC board? Yes  4-3
No 4-5
4-3 Disconnect the connector mentioned above on the control PC board of the indoor unit control PC board, and see whether the E04 goes off after several minutes. (When doing so, if two remote controllers are being used and the wireless remote controller is the main remote controller, set the other remote controller as the main.) Yes 4-4 
No 4-5 
4-4 Replace all optional control PC board and/or wireless remote control parts including wiring.
4-5 Is the LED on the indoor unit control PC board blinking? Yes 4-6
No 4-7 
4-6 The nonvolatile memory (EEPROM) on the indoor unit’s control PC board is either not installed, improperly installed or the nonvolatile memory is faulty. Correct this or after replacing the nonvolatile memory, write model data to it in the remote control detailed settings mode.
4-7 Are all the remote controllers of the other indoor units connected to that outdoor unit displaying E04? Yes Replace the outdoor unit control board
No Replace the indoor unit control board
  • The ‘/’ in the table indicates the DC motor’s indoor unit board/AC motor’s indoor unit board.
  • There is no TEST pin on the AC motor’s indoor unit board.
  • Regarding the remote controller check, refer to the Reference Materials.
  • For information on the procedures for replacing the nonvolatile memory (EEPROM) of the indoor unit and/or replacing the indoor unit’s control board, refer to the manual that is packaged with the indoor unit service board.
